 7. New MXG documentation rewrite is in progress.                       
                                                                        
    Yes, there will be new printed documentation, which will combine    
    the 1984 MXG Guide, the 1987 MXG Supplement, and the 700 pages of   
    MXG Technical Newsletters, plus the notes and text buried in the    
    various members of the MXG library.                                 
                                                                        
    No, the new books will not be completed in 1992. (In last 1991 we   
    re-printed both the 1984 MXG Guide and 1987 MXG Supplement to       
    ensure we do not run out of print until the new books are done!)    
                                                                        
    The complete re-write of MXG documentation began in the fall of 1991
    and is still in progress.  With over 1,000 MXG-built data sets and  
    over 40,000 variables, the new Chapter FORTY style documentation    
    would total over 4,200 printed pages, the equivalent of 6 books the 
    size of the 1984 Guide, just for data set documentation!  This brief
    analysis led to the following plan of attack.                       
                                                                        
    For each "Product" or "Data Source" supported by MXG, there is a    
    VMAC.... member which reads those data records and creates one or   
    more MXG data sets.  For each of these VMAC.... code members, there 
    will (eventually!) be an ADOC.... member that documents that data   
    source.  Each ADOC.... member will not only contain the data set    
    and variable descriptions now found in sections of Chapter FORTY,   
    but will also document the "Product" itself.  The ADOC.... format   
    is still being finalized, but each ADOC...  will contain several    
    sections:                                                           
                                                                        
    Product Information:  Vendor, vendor's manuals, how to create the   
                          data records, releases supported, etc.        
    Data Set Information: Contents of each data set created by MXG from 
                          this product, like existing Chapter FORTY with
                          alphabetic list of all variables.             
    Variable clusters:    Grouping of MXG variables by logical grouping 
                          (CPU, I/O, memory, response, owner, etc.). See
                          page 424 in the MXG Supplement for example.   
    Report mappings:      For important reports from the vendor (eg. IBM
                          RMF reports), a sample report showing which   
                          MXG variable name creates each report value.  
                          See page 454 in the Supplement for an example.
    PRINT/MEANS           An edited PROC PRINT of actual observations of
                          each MXG dataset shows the variable name, its 
                          label, and actual values, (which I personally 
                          think is the best way to understand datasets).
                          A PROC MEANS with minimum and maximum values  
                          of all numeric variables is also provided.    
    Technical reports:    Technical papers, discussions, or other useful
                          information relating to each product will also
                          be included in that products ADOC.... member. 
                                                                        
    Currently, 200+ "Products" have been identified, and thus there will
    be at least that many ADOC.... members.  As evidence of progress in 
    the documentation revision, twenty-five ADOCs now exits in MXG 10.1,
    although none yet contain all of the above sections.  As ADOCs are  
    completed, they are added to the next MXG PreRelease.               
                                                                        
    In addition to revising Chapter FORTY into the ADOC.... members, the
    other 41 chapters will also be revised, combined, and indexed, and  
    will be made available initially online in the MXG source library.  
                                                                        
    At this time, I envision the future MXG printed documentation will  
    consist of three separate (potentially multi-volume) "books":       
                                                                        
    a. A "Beginners Guide to MXG Software", subtitled, "What do I do    
       now that my boss just told me I am the MXG Technican?".  This    
       book will describe how to install, re-install, and use MXG and   
       will deal exclusively with MXG architecture, execution, etc.     
       The member NEWUSER is a start in this documentation.             
                                                                        
    b. A "Documentation of Products Supported by MXG", comprising the   
       above mentioned ADOC.... members.  The IMACAAAA member is the    
       best index of the product's that are supported by MXG, although  
       searching CHANGESS for the product name or abbreviation may be   
       needed due to product renames.                                   
                                                                        
    c. A new "Advanced Guide to CPE" text consolidating all of the      
       other forty-one chapters, plus additional new information.       
       Among my other dreams to be done, maybe, sometime.               
                                                                        
    ALL FUTURE MXG DOCUMENTATION WILL ALWAYS BE PROVIDED INITIALLY IN   
    MACHINE READABLE FORMAT AS PART OF THE MXG SOFTWARE.  Portions of   
    that online documentation will also be available in printed format. 
                                                                        
II.   MXG Technical Notes                                               
                                                                        
 1. Can I Execute MXG on a PC or a UNIX workstation?  An MXG Position.  
                                                                        
  A. The building of MXG "Performance Data Bases" must be done under a  
  mainframe version of SAS, at least for the short-term foreseeable     
  future.  There are several factors that inhibit the use of a PC or a  
  UNIX workstation to create MXG data sets from raw data records:       
                                                                        
   1. The current SAS compiler interprets INPUT statement informats     
      based on the execution platform.  On the mainframe, $CHAR expects 
      EBCDIC values, but under PC/VAX/UNIX, $CHAR expects ASCII values. 
      Similarly, PD4, PIB4, RB4, informats expect the data format of the
      executing environment; different platforms store binary data in   
      different formats, and using PIB4 in a PC program to read SMF data
      will produce incorrect numbers. (Some mainframe-specific informats
      like SMFSTAMP and RMFDUR do not yet exist on all SAS platforms.)  
      Additionally, sort orders, like input formats, are intrepreted for
      the execution platform; ASCII vs EBCDIC and ascending/descending  
      differences could render some MXG algorithms invalid.             
                                                                        
      This constraint will exist at least until a SAS Version 7 exists, 
      (years, not months) because removing it requires a significant    
      change to the design of the SAS System.  I have asked the SAS     
      Institute to remove this limitation, by providing an option that  
      allows us to specify the environment under which the DATA step    
      input formats, sort order, etc., are to be interpreted.  SAS      
      designers agree that the limitation should be removed, and are    
      evaluating implementation strategies for the future SAS version.  
                                                                        
      SAS does provide some mainframe informat names (eg, the S370xxxx  
      informats) that do interpret mainframe data values under PC SAS,  
      but their use requires source changes to all 400,000 lines of MXG,
      with more than just substitution - algorithms for nonexistent data
      formats require insertions in multiple locations per occurrence.  
      A separate MXG source library would be needed for each platform on
      which it would be executed, a maintenance burden for both of us!  
                                                                        
   2. A personal computer or departmental mini-computer is the wrong    
      place for performance data.  The performance/capacity/accounting  
      PDB is a strategic and tactical corporate information source and  
      corporate asset used by technicians, managers (operations,        
      software, technical support), their directors, company presidents 
      and often by corporate executives.  Asking them to walk down the  
      hall to your PC to look at the capacity graphs seems less         
      appropriate than having the PDB on a mainframe where they can all 
      view the single (and hence unambiguous) PDB information at their  
      own desk without a download and without bugging you to look over  
      your shoulder.                                                    
                                                                        
      Shared corporate data belongs on mainframes and personal data     
      belongs on personal or departmental machines.                     
                                                                        
   3. The volumetrics are wrong for personal or departmental computers. 
      The daily SMF volume for a mainframe is measured in hundreds of   
      megabytes.  500K CICS transactions are 200MB of raw SMF data.  At 
      9600 baud, it takes 24 hours to download 100MB! Even channel      
      attached PCs take hours per 100MB, and then more hours after the  
      download to create the SAS data libraries, which will need disk   
      volumes measured in hundreds of megabytes for the temporary       
      datasets while building the PDB.  Current mainframes are 40-80    
      times faster for "real data processing (i.e., lots of I/O)"       
      workloads than are current 486 PCs and UNIX workstations.         
                                                                        
                                                                        
      I believe that the MXG application at your site reads more input  
      data bytes per day than any other (and probably more than all     
      other) business applications on your mainframe processor!  Buying 
      a PC or a UNIX box for this kind of business application is a     
      misapplication of the present technology.                         
                                                                        
                                                                        
  B. Building MXG data bases in the future may be different.  Already we
  are testing MXG programs under SAS 6.07 and OS2 Release 2 on a 400MB  
  Model 95 PS/2 (soon with a 3480 IDRC tape drive!), not because we     
  think that is the way to go, but because we want to make sure that    
  when it does become feasible, and when the SAS limitations have been  
  removed or circumvented, MXG will be ready!  (Even then, I believe    
  mainframe SAS will continue to be the place to build your PDBs!)      
                                                                        
                                                                        
  C. Please note carefully that the limitations in preceding paragraphs 
  deal only with the BUILDING of large, shared performance data bases.  
                                                                        
  Once the "PDB" has been created on the mainframe, it can be completely
  appropriate to use a personal computer for personal analysis or for   
  development and testing of reports.  The PDB, consisting of many,     
  mostly small, SAS datasets, can be efficiently processed on today's   
  PCs.  Most sites with PC devices for color plotters and printers now  
  use SAS/GRAPH cooperatively between their mainframes (where they build
  the graph) and their PC (where they PROC GREPLAY the results).        
                                                                        
  It is possible to generate the graphs without a mainframe SAS/GRAPH   
  license, by downloading PDB datasets to a PC or workstation that then 
  does the PROC GPLOT to build graphs on the PC, but this may be a poor 
  choice and false economy, since a PROC GPLOT that takes only one      
  second on your 3090 can easily take one minute on your PC, not even   
  including the time to download the MXG dataset in the first place.    
  The savings in your time alone may well justify the costs for the     
  second SAS/GRAPH license, and you have the power and storage of a     
  mainframe to keep graphs available for replay.  The generation of     
  graphics is a CPU-intensive process; there are times when it should be
  executed on the mainframe, and there are times when it can be executed
  on the PC.  The best implementation is to have SAS/GRAPH available on 
  both platforms, and (eventually, in future SAS versions) let SAS      
  decide what runs where!                                               
                                                                        
                                                                        
 2. Will SAS 6.07's compress option help MXG?                           
                                                                        
  Because MXG has always used LENGTH DEFAULT=4 to minimize the size of  
  its datasets, the COMPRESS option cannot save as much DASD space      
  with MXG as it will with other SAS applications which use the SAS     
  default length of 8 bytes for numeric variables.  Nevertheless, it is 
  appropriate that we investigate the possible use of COMPRESS=YES.     
                                                                        
  One benchmark of BUILDPDB with 470MB input SMF data shows the cost to 
  compress all datasets: the CPU time increased significantly (65%, from
  535 to 883 seconds) but only reduced the WORK library size by 16% and 
  only reduced the PDB library by 20%.                                  
                                                                        
  A second run compressing only CICSTRAN and DB2ACCT datasets showed the
  CPU time increase was less but still appreciable (37%, from 472 to    
  645 seconds in the data step alone), but the CICSTRAN dataset was     
  reduced by 37% and DB2ACCT was reduced by 44%.  Thus, if you must put 
  these two datasets on DASD, compression will, at some CPU cost, save  
  appreciable DASD.  However, it has always been MXG's recommendation   
  to store large volume transaction datasets (like CICSTRAN and DB2ACCT)
  directly on tape to avoid contamination of DASD space, and SAS 6.07   
  does not support compression of tape data libraries!                  
                                                                        
  Compression does reduce the size of MXG datasets as shown, but the    
  CPU cost is appreciable.  These initial benchmarks suggest strongly   
  that the COMPRESS option will not likely be used by default in MXG,   
  but for sites that have large-volume transaction datasets that must be
  stored on DASD, the CPU cost of compression may be justified by DASD  
  savings.  MXG member IMACKEEP can be used to specify COMPRESS=YES for 
  specific datasets, and further enhancements to MXG will make it even  
  easier to specify individual options, such as COMPRESS, for specific  
  MXG datasets.                                                         
                                                                        
                                                                        
 3. How do I run the PDB if my data center runs only six days a week?   
                                                                        
   Sites which operate six days a week need to make only minor changes  
   to the architecture of BUILDPDB/WEEKBLD/MONTHBLD.  The PDB that would
   normally be built on Sunday morning and that would normally be copied
   into the SAT "day-of-week" dataset will not exist if your site does  
   not run BUILDPDB on Sunday.                                          
                                                                        
   If SAS would allow it, you could use  //SAT DD DUMMY but SAS Version 
   6, unfortunately, does not tolerate DD DUMMY for SAS data libraries. 
                                                                        
   You could modify MXG and remove all references to SAT in members     
   WEEKBLD and MONTHBLD and your JCL for BUILDPDB, WEEKBLD, and MONTHBLD
   and I once suggested that approach.  But here's Chuck's better way:  
                                                                        
   Create the SAS equivalent of DD DUMMY by allocating a one cylinder   
   SAS data library for your SAT or SUN PDB (or both, if you're a 5x24  
   instead of a 6x24 operations!).  You then execute                    
        OPTIONS OBS=0; PROC COPY IN=PDB OUT=SAT; RUN; OPTIONS OBS=MAX;  
   to build a valid zero-observations SAT or SUN PDB library.  You can  
   then use the normal MXG JCLPDB6 JCL, and your MXG tailoring will be  
   limited to MONTHBLD, discussed below.   However, there is another    
   big advantage of this implementation.  When you do grow up again to  
   operate 7x24, you simply create a new and larger dataset for that    
   seventh day that is being added, and you keep on trucking!           
                                                                        
   However, if you operate only six days a week, you must also alter the
   logic in MONTHBLD and in the logic that submits the MONTHBLD job:    
                                                                        
   The logic of MONTHBLD must be changed, because if the 1st day of the 
   month is a Sunday, then the monthly job must be executed on Monday   
   the 2nd day of the month.  These specific changes must be made:      
                                                                        
   MONTHBLD  -  These changes are required:                             
                                                                        
        a. replace   IF DAY(TODAY) NE 1 THEN DO;                        
           with                                                         
             IF NOT (DAY(TODAY) EQ 1 OR (DAY(TODAY) EQ 2 AND DAY='MON'))
               THEN DO;                                                 
                                                                        
        b. insert     IF DAY(TODAY) EQ 2 THEN TODAY=TODAY-1;            
           immediately before    LASTDAY=TODAY-1;                       
                                                                        
    SUBMIT logic.  The example on page 343-4 of the MXG Guide shows how 
      to use SAS to submit the monthly jobs from the daily BUILDPDB on  
      the first day of the month that is not a Monday using:            
        IF DAY=1 AND WDAY NE 'MON' THEN MONTHFLG=1;                     
      The text points out that if the first day of the month is a Monday
      the monthly job will be submitted by a "similar step attached to  
      the weekly job so that the monthly job uses the weekly dataset".  
      That "similar step" would contain only the second DATA _NULL_ step
      in the example, and (for seven day operation) it would contain:   
        IF DAY=1 AND WDAY EQ 'MON' THEN MONTHFLG=1;                     
                                                                        
      For six day operation, only that "similar step" tacked on to the  
      end of your weekly job needs to be changed to now read:           
        IF (DAY=1 OR DAY=2) AND WDAY EQ 'MON' THEN MONTHFLG=1;          
                                                                        
    Note that MXG architecture requires that the daily BUILDPDB job     
    complete before the WEEKBLD job is submitted on Monday, and that the
    WEEKBLD job complete before MONTHBLD is submitted.  This is easily  
    accomplished by letting the BUILDPDB submit WEEKBLD/MONTHBLD and    
    letting WEEKBLD submit MONTHBLD when the month starts on Sunday or  
    Monday.                                                             
                                                                        
    With six day operation, the data for Saturday and Sunday work will  
    be put in the SUN library with a ZDATE of Monday's date.  Since the 
    selection criteria for a month are the ZDATEs of the 2nd of last    
    month thru the 1st of this month (inclusive), the combined weekend  
    data will be put in last month's PDB when the month starts on Monday
    and the combined weekend data will be put in next month's PDB when  
    the month starts on Sunday.

IV.   CICS Technical Notes                                              
                                                                        
 1.CICS/ESA 3.3.0 was incompatibly changed by IBM.  New data fields were
   inserted in the middle of the records!  MXG 9.9 does not ABEND with  
   CICS 3.3.0 records (it does print "UNEXPECTED DATA FOUND" notes on   
   the SAS log as a warning that something is wrong), but the CICSTRAN  
   dataset is essentially trashed; transaction start/stop/response times
   are valid, but all resources (CPU time, File Control counts, etc.)   
   are completely wrong.  MXG 10.1 is REQUIRED for CICS/ESA 3.3 records.
                                                                        
 2.Omegamon V550 support requires installation tailoring.               
   a. MXG members IMACICOC, IMACICOL, and IMACICOB (for the BSC, DLI,   
      and DB2 additions to the transaction record) contains a comment   
      block which surrounds that actual code.  That comment block must  
      be deleted to enable processing of these three Omegamon segments. 
   b. MXG member IMACICDA controls which CICS APPLIDs have Omegamon data
      segments.  If only some CICS APPLIDs have Omegamon data, you must 
      add a DO group for those APPLIDs around the three %INCLUDEs for   
      the three members above, so they are only included for the correct
      APPLIDs.                                                          
   c. For CICS 2.2 or earlier (SMFPSRVR=3) you must tailor member       
      IMACEXCL to process the excluded fields in the basic transaction  
      segment.  You use macro _CICXLTR to name the APPLIDs writing the  
      Omegamon records, and you use macro _CICXCTR to specify _CICXCOM  
      so that the Omegamon exclude structure is used for those APPLIDs. 
      This step is not required under CICS/ESA, because Omegamon does   
      not exclude transaction fields under CICS/ESA.                    
   d. If MCTSSDRL=496 in the MXG VMAC110 error message, you must also   
      update member IMACPTF and in therein enable macro QOC0109.  This  
      note was added to the online member Aug 24, 1994.                 
                                                                        
V.    SAS Technical Notes.                                              
                                                                        
 1.BUILDPDB (with additional SMF record processing) under SAS 6.07 has  
   produced "NOTE: ADDITIONAL INTERNAL PASS WAS REQUIRED TO COMPUTE     
   CORRECT CODE SIZE. SPECIFYING OPTION CODEPCT=102 MAY REDUCE EXECUTION
   TIME.", but MXG's CONFIG07 member specifies CODEPCT=120! This appears
   to be a very minor SAS bug that is under investigation, that has no  
   effect on the MXG execution of BUILDPDB.  However, this note caused  
   me to benchmark a related compiler option, CODEPASS.  In theory,     
   specifying CODEPASS=2 for large programs should be faster, since SAS 
   is committed to a two-pass compile, instead of starting to one-pass  
   compile and finding a second pass necessary, but it did not have that
   effect on MXG's BUILDPDB with SASENTRY=SASHOST.   With CODEPASS=2,   
   the CPU time (exactly repeatable) increased by 1.04 seconds (from    
   49.15 to 50.19), or 2% increase, and the elapsed time was a wash     
   (down .63, 91.85 to 91.22 in one pair, up .36, 95.54 to 96.30 in the 
   second pair).  Since CODEPASS=1 is slightly cheaper, CODEPASS=2 is   
   not recommended for BUILDPDB.                                        
                                                                        
 2.SAS 6.06 Error 31-185, Format not recognized, occurs if the SAS      
   installer was sloppy and tried to create a Version 6 JCL Procedure by
   modifying your existing Version 5 procedure.  The Version 5 PROC has 
   a //LIBRARY DD DSN=&LIBRARY,DISP=(MOD,DELETE) statement that does not
   belong in Version 6.  Have your SAS Installer correct your problem by
   installing the Version 6 JCL Procedure provided by SAS Institute.    
                                                                        
 3.JCLTEST6 JCL 4MB REGION too small if MEMSIZE is limited by site.     
   Two sites have reported they could not successfully execute TESTIBM3 
   step of JCLTEST6 in a 4MB Region with MXG's CONFIG member default of 
   24MB; they had to increase the REGION JCL parameter to 6MB to run.   
   At least one of the sites had limited the amount of virtual storage  
   above the line to 16MB, and thus SAS could not get the 24MB MEMSIZE  
   MXG expected.  Increasing the REGION size is the only alternative if 
   you cannot get enough MEMSIZE above the line!                        
                                                                        
 4.SAS 6.07 INFILE processing of concatenated files is not perfect if   
   END=END is specified.  The JCFB= variable is incorrect and contains  
   the 2nd concatenation's DSNAME while still on the last record of the 
   1st concatenation.  Additionally, the SAS NOTE: describing the next  
   data set is printed too early on the SAS log (before messages from   
   the last record in the 1st concatenation).  Tracking 238735.  Only if
   you use the JFCB= variable (to capture DSNAME?) are you at risk.  MXG
   only uses the JFCB= variable initially to discern if the input data  
   is VSAM or BSAM, and thus this error poses no risk to MXG code.      
                                                                        
 5.SAS 6.06 and SAS 6.07 require BLKSIZE=23040 override to avoid error. 
   SAS 6.06 may still ABEND with the erroneous error message "DATA SET  
   IS NOT SORTED", indicating bit overlays in the WORK DDname.  These   
   errors have nothing to do with the SORT program, but were thought to 
   be mostly fixed by SAS Oct 1991 Maintenance.  There were still some  
   known exposures that could not be fixed by zap, that were thought to 
   have been fixed in SAS 6.07 (remember, 6.07 allowed SAS to corect at 
   source level, instead of by ZAP).  A circumvention for SAS 6.06 sites
   until they install SAS 6.07 has been to follow MXG's performance     
   recommendation of BLKSIZE=23040 for WORK DD because it appears that  
   the bit overlay error is eliminated by the larger block size (instead
   of the 6144 SAS default)!.  See page 35, MXG Newsletter TWENTY-ONE,  
   for the JCL example to override WORK DD.  One SAS 6.07 site reported,
   without confirmation, a similar failure that was seemingly also      
   eliminated by large blocksize for WORK DD.                           
                                                                        
 6.SAS 6.07 error in the CCHHR option causes VMXGVTOC to miss extents   
   and produce "CRITICAL ERROR IN VTOC PROCESSING" if there are more    
   than three extents.  SAS ZAP V6-SYS-FILE-4673 is available on the    
   June 1992 SAS Usage Notes Tape.  This error was apparently only in   
   the CCHHR option, and not the similar but different CCHHR= option.   
   This error did not affect the recommended alternative to VMXGVTOC,   
   the ASMVTOC/VMXGVTOF members which are faster, better, and do not use
   either CCHHR or CCHHR= options.                                      
                                                                        
 7.SAS 6.07 does not recognize the EPILOGC infile exit name, used to    
   processing Candle's (archaic) EPILOG compressed records, while SAS   
   6.06 did.  Fortunately, the current EPILOG V550 product writes data  
   to SMF records without compression, so few sites should encounter    
   this SAS error.                                                      
                                                                        
 8.SAS 6.07 may produce INVALID ALTER PASSWORD error message.  Two SAS  
   usage notes, V6-SYS-SASIO-4267 and -4147, discuss separate problems  
   related to the PROTECT option and Version 5 or 6.06 datasets.        
                                                                        
   One site had a SPIN library that had been originally created by SAS  
   5.18.  Their SAS 6.07 BUILDPDB failed when it started to write out   
   the new day's SPIN data sets, because that Version 5 SPIN library had
   been built with PROTECT enabled.  (PROTECT was removed in 6.06 but   
   apparently causes SAS 6.07 to unexpectedly fail!).  By creating a    
   6.07 SPIN library and using PROC COPY to copy the SPIN datasets to   
   the 6.07 SPIN library, this site's problem was circumvented with no  
   loss of data:                                                        
                                                                        
      //SPIN607  EXEC SAS607,CONFIG=MXG.SOURCLIB(CONFIG07)              
      //SPIN  DD DSN=OLD.SPIN.LIBRARY,DISP=OLD                          
      //NEWSPIN DD DSN=NEW.SPIN.LIBRARY,DISP=(,CATLG),...               
         PROC COPY IN=SPIN OUT=NEWSPIN                                  
                                                                        
   One site failed in WEEKBLD when it went to overwrite the WEEKly      
   library.  The PROC CONTENTS showed the ENGINE=TAPE, indicating the   
   library had been created with SAS 6.06's Tape engine, and usage note 
   4147 indicates that cannot be done without error under 6.07.  In this
   case, simply by scratching and re-allocating the WEEKly library      
   (since the weekly data had already been copied to tape) circumvented 
   the problem.                                                         
                                                                        
 9.SAS 6.07 copy from SMF VSAM file to BSAM VBS file creates invalid SMF
   records; error is fixed by SAS ZAP MV313550.  See Change 10.030.     
                                                                        
10.SAS 6.07 entry modules SASXA1 and SASXAL may ABEND with 0C4 at SAS   
   initialization.  The culprit appears to be IBM's IEBCOPY option      
   COPYMOD, used to build and re-block these "bundled" programs.  The   
   COPYMOD option seems to create double RLD entries (they can be seen  
   in an AMBLIST of the ABENDing module).  Using IEBCOPY option COPY    
   instead of COPYMOD did not create double RLDs and SAS did not ABEND. 
   The COPYMOD statement which needs to be changed is found in member   
   CPYBA2 of the SAS install library; see step BACOPY2 in SASUPDTE job. 
   This has hit two sites, and research is still in progress. The ABEND 
   only occurs in batch execution. Tracking 244913, still open.         
                                                                        
VI.   Installation, re-installation, and Space Requirements.            
                                                                        
    Over 20 Beta sites have been running MXG 10.1, some since mid May,  
    with no reported problems, either in execution or migration from    
    9.9.  There are no changes in the external (JCL) environment for MXG
    10.1, and the installation instructions are unchanged from MXG 9.9. 
                                                                        
    Sites migrating to 10.1 from an MXG version earlier than 9.9 must   
    read the compatiblity section of the installation instructions in   
    MXG Newsletter TWENTY-ONE.                                          
                                                                        
Always read comments in the CHANGES member for compatibility issues, as 
well as for any last minute changes added after Newsletter composition. 
                                                                        
The MXG Installation instructions are found in Chapter 32 of the MXG    
Supplement for both new installation and for version replacement, and   
those instructions, as modified herein, are still valid.                
                                                                        
The MXG tape is distributed as a Non-Labelled (NL) tape containing a    
single file with DCB=RECFM=FB,LRECL=80,BLKSIZE=32720.  The MXG tape is  
an unloaded Partitioned Dataset in IEBUPDTE format.  Note that the tape 
blocksize was changed to 32720 (it had been 6160 in prior versions). You
will receive I/O errors if you specify the incorrect blocksize.         
                                                                        
Under MVS use IEBUPDTE utility to build the MXG.SOURCLIB PDS library.   
Under CMS use TAPPDS   command to build the SOURCLIB MACLIB library.    
                                                                        
Allocate MXG.SOURCLIB for MXG 10.1 with SPACE=(CYL,(54,1,299)), using   
  DCB=(RECFM=FB,LRECL=80,BLKSIZE=23440) on 3380 devices, or             
  DCB=(RECFM=FB,LRECL=80,BLKSIZE=27600) on 3390 devices.                
                                                                        
Under CMS, approximately the same space (54 cylinders) will ultimately  
be required by the MXG SOURCLIB MACLIB, but during the CMS installation 
process you will need at least 108 free cylinders on your minidisk.     
                                                                        
MXG is tailored and extended by "Installation Macro" members (members   
beginning with IMAC....), and by "MXG Exit Facility" members (members   
beginning with EX....) that are copied and edited into the installation 
"USERID.SOURCLIB", the name of the "MXG Tailoring" library, that you    
create and concatenate ahead of MXG.SOURCLIB to the SOURCLIB DDNAME:    
                                                                        
  //SOURCLIB DD DSN=USERID.SOURCLIB,DISP=SHR --> site tailoring (yours) 
  //         DD DSN=MXG.SOURCLIB,DISP=SHR    --> never changed  (mine)  
                                                                        
If this is an MXG re-install, there should already be a USERID.SOURCLIB.
If not, then allocate one using the same attributes as the MXG.SOURCLIB,
with SPACE=(CYL,(1,1,99)).  Under CMS create an equivalent MACLIB.      
                                                                        
Tailor by editing members that you copy from my library to your library.
                                                                        
IMAC.... members are self-documenting, and member IMACAAAA indexes all  
IMAC members.  Most MXG sites have only a few tailoring members in their
USERID.SOURCLIB (typically, IMACACCT, IMACSHFT, IMACWORK).              
                                                                        
VMAC.... members contain the actual processing code, and normally should
not exist in your USERID.SOURCLIB, and should always be removed when you
install a new version of MXG.  However, if you have installed printed   
changes from an MXG Newsletter, you might have copied VMAC member(s)    
from MXG.SOURCLIB into your site's USERID.SOURCLIB and then modified the
VMAC member.  (Alternatively, you could have created an MXG.CHANGLIB in 
which you put those in-between-version changes.)  In either case, if    
you made temporary changes, they must be removed now.  Delete all of the
VMACs members from your USERID.SOURCLIB (or delete the MXG.CHANGLIB).   
Otherwise, your modified VMAC member would be used instead of MXG's.    
                                                                        
You should record all tailoring changes in your USERID.SOURCLIB so the  
next MXG technician will know what you have done.  You should create a  
member named CHANGES in your USERID.SOURCLIB, similar to member CHANGES 
in the MXG.SOURCLIB which documents all MXG changes.                    
                                                                        
If there are IMAC.... members in your USERID.SOURCLIB, you must look at 
the alphabetic list of changed IMACs in the Change Log, below, and must 
retrofit your tailoring on the new member in this library.  MXG 10.1    
changed IMACPDB to add TAPE3490 device count.                           
                                                                        
Whenever you install changes or test a new version of MXG (or even your 
own reports), be extra careful to look on the SAS log for any real error
conditions. Search for all occurrences of "ERROR:" and  "ERROR :"  and  
"UNINITIALIZED" and "NOT CATLGD", as they may indicate a serious error. 
                                                                        
A PROC PRINT and a PROC MEANS of each new MXG-built SAS dataset can help
you to understand their contents, and should be used to examine any     
unusually large, negative, or suspicious values.  Print all variables in
the dataset, and read the variable's descriptions in Chapter FORTY.     
                                                                        
                                                                        
 Summary of critical actions to be taken in installing new version:     
                                                                        
     a. All VMAC.... members in your USERID.SOURCLIB must be examined   
        and, in general, must be deleted.                               
                                                                        
     b. All IMAC.... members in your USERID.SOURCLIB must be compared   
        with the IMAC.... members that have been changed in this MXG    
        version (see alphabetic list at beginning of Change Log).  You  
        MUST start with the IMAC in this version and retrofit your      
        installation's tailoring. Member IMACAAAA indexes all IMAC's.   
                                                                        
     c. It is always wisest to PROC PRINT the first 50 observations of  
        important datasets, especially PDB.JOBS, which can be affected  
        by user tailoring in IMACPDB. A visual scan of that PROC PRINT  
        serves as an excellent validation of correct installation, and  
        will almost always detect any serious problems BEFORE you begin 
        your production MXG runs!

VII.  Important notes from prior Newsletters:                           
                                                                        
 1. SAS OPTIONS REQUIRED under version 5.18, 6.06, or 6.07.             
                                                                        
    Please read this section carefully.  MXG execution will fail if you 
    do not pay attention to these (potentially incompatible) changes:   
                                                                        
    SAS options that are MANDATORY with all SAS Versions:               
                                                                        
      NOIMPLMAC MAUTOSOURCE SASAUTOS=SOURCLIB ERRORABEND MACRO DQUOTE   
                                                                        
        NOIMPLMAC should ALWAYS be used; never use IMPLMAC.             
        MAUTOSOURCE and SASAUTOS=SOURCLIB are required by MXG to        
         resolve %MACRO references without extra I/O by using autocall. 
        ERRORABEND ensures SAS stops on any error condition.            
        MACRO enables SAS to recognize %MACROs.                         
        DQUOTE is needed to extract values of certain string %MACROs.   
                                                                        
    SAS options MANDATORY under SAS Version 5.18 (do not exist in V6):  
                                                                        
      MWORK=28000 GEN=0                                                 
                                                                        
        MWORK was needed in large %MACROs (like %ANALDB2R).             
        GEN=0 was needed to eliminate unnecessary I/O and CPU time, and 
        is discussed in the 1984 Guide (see Index).                     
                                                                        
    SAS options MANDATORY under SAS Version 6 (did not exist in 5.18):  
                                                                        
      MEMSIZE=24M                                                       
                                                                        
        Previously, MXG recommended MEMSIZE=12M, but programs that build
        many datasets concurrently (like BUILDPDB, VMACVMXA, etc.) will 
        need more of this virtual storage above the line, because of the
        new MXG recommended value for BLKSIZE='half-track'. The MEMSIZE 
        option only works under MVS/XA and MVS/ESA, and since it is not 
        a real resource, and only used when needed during the "building"
        phase in MXG processing, the new default of MEMSIZE=24M should  
        not cause any problem, and will avoid unnecessary ABENDs.       
                                                                        
        If you are using MXG and SAS 6.07 under MVS/370 or CMS/370, you 
        will have to reduce this MEMSIZE= parameter to no more than 6M, 
        and must reduce the BLKSIZE (try 4096, or the minimum 1024).    
        Small BLKSIZE will allow your program to compile, but the DASD  
        work space you will need will significantly increase, as will   
        the run-time, IOs, and CPU requirements for the same job.       
                                                                        
    SAS options STRONGLY RECOMMENDED for SAS 6.06/6.07 performance:     
                                                                        
      BLKSIZE=23040 BUFNO=2   -- for 3380's                             
      BLKSIZE=27648 BUFNO=2   -- for 3390's                             
                                                                        
      MXG now uses BLKSIZE(DASD)=HALF in CONFIG/CONFIG07 members to set 
      the blocksize for new permanent data sets, but that option will   
      not work if the BLKSIZE was specified in the JCL.  The //WORK DD  
      contains an explicit BLKSIZE=6144 parameter, which must either be 
      changed in your SAS procedure or overridden in your JCL, using:   
                                                                        
           //    EXEC MXGSASV9                                          
           //WORK DD DCB=BLKSIZE=23040                                  
                                                                        
      See "SAS Benchmarks" in Newsletter TWENTY for resource savings.   
                                                                        
    SAS options recommended with either SAS Version 5.18, 6.06 or 6.07: 
                                                                        
        FIRSTOBS=1 OBS=MAX                                              
        ERRORS=2                                                        
        NOSOURCE NOSOURCE2 NOMACROGEN NOMPRINT NOMLOGIC                 
                                                                        
    So how do you specify these recommended/required MXG options?       
                                                                        
    In Version 5.18, MACRO and MWORK=28000 must be specified on the EXEC
    statement, but all other options could be specified on an OPTIONS   
    statement right after your SYSIN DD * statement.  However, so you do
    not have to remember them nor type them, MXG member SASOPTV5 has all
    of the recommended options in an OPTIONS statement, so you need only
    %INCLUDE SOURCLIB(SASOPTV5);  as your first SAS statement:          
                                                                        
                                                                        
         //stepname EXEC SAS518,OPTIONS='MACRO MWORK=28000'             
         //SYSIN     DD *                                               
            %INCLUDE SOURCLIB(SASOPTV5);                                
             ... the rest of your program ...                           
                                                                        
    For SAS Version 6, options can be set with an OPTIONS statement, or 
    with the OPTIONS= JCL parameter, or (as is MXG's recommendation) via
    the CONFIG= JCL parameter on the EXEC statement.  MXG member CONFIG 
    contains the MXG required and recommended options for SAS 6.06, and 
    member CONFIG07 contains the SAS 6.07 recommendations.  The BLKSIZE 
    and MEMSIZE options were increased in MXG 9.9, and the new CONFIG07 
    member was added with new SAS 6.07 options.  (You could also supply 
    options by overriding the CONFIG DD in the SAS JCL procedure, but   
    using the CONFIG= parameter is safer and simpler.).                 
                                                                        
         // EXEC SAS606,TIME=10,                                        
         //            CONFIG='MXG.SOURCLIB(CONFIG)'                    
                                                                        
                                                                        
         // EXEC SAS607,TIME=10,                                        
         //            CONFIG='MXG.SOURCLIB(CONFIG07)'                  
                                                                        
    IF YOU DON'T HAVE THE RIGHT OPTIONS IN EFFECT, YOU WILL RECEIVE     
    RUDE AND INSULTING SAS ERROR MESSAGES, INCLUDING 180 ERRORssss!     
                                                                        
                                                                        
 2. Format libraries are different in MVS SAS Version 6 and Version 5.  
                                                                        
    The MXG-built "SASLIB" formats are built by the first step of either
    JCLTEST (for SAS 5.18) or JCLTEST6 (for SAS 6.06).                  
                                                                        
    Under SAS Version 5.18, formats are members of a PDS load library   
    which must be allocated as SPACE=(CYL,(3,1,99)).  SAS 5.18 formats  
    are always referenced using the DDNAME of SASLIB.                   
                                                                        
    Under SAS Version 6 formats are members of a SAS data library, which
    must be allocated as SPACE=(CYL,(1,1)). Note there is NO third SPACE
    parameter (for PDS directory blocks), because data libraries in SAS 
    Version 6 are physical sequential files.  SAS Version 6 format      
    libraries are always referenced using the DDNAME of LIBRARY.        
                                                                        
    In either version of SAS, the blocksize is set by the PROC FORMAT.  
                                                                        
    MXG always requires the appropriate DDNAME (SASLIB or LIBRARY).     
                                                                        
    You will fail with SAS 170 FORMAT NOT FOUND errors if you do not    
    have the correct format library pointed to by the correct DDNAME.   
                                                                        
VIII. Documentation of MXG Software.                                    
                                                                        
                                                                        
Member CHANGES always contains the version number of MXG Software, and  
it lists changes that were installed in that version.  The members named
CHANGEnn have the contents of CHANGES when that "nn" MXG version was    
created.  Description of enhancements will be found in the text of the  
Change description that made the enhancement (in those CHANGES and      
CHANGEnn members).  The CHANGE  members can be scanned online (with SPF 
BROWSE) to search for specific product name references (CICS, MVS/ESA,  
etc.).  The text of each Change identifies the member(s) that were added
or altered by that change. Documentation (especially for new product's  
support) is usually also found in comments at the beginning of those    
members listed in the change entry.                                     
                                                                        
Member NEWSLTRS contains the text of all newsletters (up through the    
newsletter that accompanied that MXG release). You can search NEWSLTRS  
for product name or acronym to find the technical notes, APARs, etc.    
from all MXG newsletters.  (The Change Log of each Newsletter is not    
replicated in member NEWSLTRS, since that text will be in CHANGES).     
                                                                        
Member DOCVERnn is the "delta-documentation" (in abbreviated Chapter    
FORTY style) of only those variables and datasets that were changed     
between successive MXG Versions. There is a DOCVERnn "delta" member in  
the MXG library for each version.                                       
                                                                        
Penultimately, member DOCVER contains abbreviated Chapter FORTY format  
that documents all of the variables names in all of the MXG data sets   
that are created by that MXG Software Version (alphabetically by data   
set name and variable name).                                            
                                                                        
Finally, MXG is a source distributed system, so you can often find your 
answer by BROWSE/EDIT of the source member, especially the VMACs that   
actually create the data set, or ANALs that analyze the MXG data sets.  
In many instance, the MXG Variable name is the IBM or Vendor's field or 
DSECT field name. In other cases, the DSECT field name is carried as a  
comment beside in the MXG INPUT statement to map field name to MXG's    
variable name.  MXG expects you to also have access to the vendor's     
documentation of particular data records you are using for analysis.    
                                                                        
IX.   Change Log                                                        
                                                                        
--------------------------Changes Log---------------------------------  
                                                                        
 You MUST read each Change description to determine if a Change will    
 impact your site. All changes have been made in this MXG Library.      
                                                                        
 Member CHANGES of the MXG SOURCLIB will always be more accurate than   
 the printed changes in a Newsletter, because the software is created   
 after the newsletter is sent to the printer!                           
                                                                        
 Member CHANGES always identifies the actual version and release of     
 MXG Software that is contained in that library.                        
                                                                        
 The actual code implementation of some changes in MXG SOURCLIB may be  
 different that described in the change text (which might have printed  
 only the easily installed, critical part of the correction).           
                                                                        
 Scan each source member named in any impacting change for any comments 
 at the beginning of the member for additional documentation, since the 
 documentation of new datasets, variables, validation status, and notes,
 are often found in comments in the source members.
