II.  MXG Technical Notes                                                
 1. Text:                                                               
III. MVS, a/k/a z/OS, Technical Notes.                                  
 5. APAR OA49128 FIN (Fixed In Next z/OS) will correct the date value in
    variable SMF92CTO in SMF 92 subtype 11; that same field is also used
    in the IPCS OMVSDATA FILE report and both will show an incorrect    
    birthdate for FIFO files (possibly LE owned). Error is in z/OS 2.2. 
 4. Review of Arney Computer Systems Trap Diagnostic Facility, TDF.     
    Assembler language developers working with System z 64-bit          
    architecture soon discover that the traditional TSO TEST command is 
    inadequate for their needs.  TSO Test only displays the last 32     
    bits of General Purpose Registers and has an antique command line   
    interface where prior displayed results soon roll off the screen.   
    Trap Diagnostic Facility (TDF) from Arney Computer Systems provides 
    a modern tool that leverages the power of the ISPF full screen      
    interface to make modern code debugging a productive and satisfying 
    All General Purposes Registers are shown on an ISPF panel without   
    having to request them.   When in Instruction Step mode registers   
    are color coded so that changed registers are immediately apparent. 
    Prior storage displays are not lost and can be scrolled to review.  
    Breakpoints can be set to trip for a single occurrence or for every 
    Some of the tasks that can be accomplished using the User Interface 
    -   Define the programs to be debugged                              
    -   Display and alter storage, registers and PSW                    
    -   Interactively trace execution at the instruction level          
    -   Set breakpoints and triggers to stop execution at desired points
    -   Review the output of previous commands in the response history  
    -   Manage Session recording and replay                             
    -   Define and initiate non-interactive traces                      
    TDF installs quickly using a simple TSO RECEIVE script to set up    
    the ISPF libraries and load library.  Because TDF uses z            
    Architecture TRAP instructions an Authorized Program Facility (APF) 
    library is required for the load modules.   TDF has a Started Task  
    for the Server task.   A TSO Clist invokes the TDF ISPF interface   
    and then only a minor change to the JCL EXEC statement for the      
    program to be tested is needed.                                     
    This product is definitely worth evaluating for installations that  
    rely on development or enhancement of assembler programs for their  
    business needs.                                                     
         Arney Computer Systems                                                                                  
 3. Pointing //LIBRARY to a PDS-E dataset instead of sequential caused: 
           MXG.PROD.SOURCE.FORMATS TO VOLUME NUMBER 1.                  
 2. TYPE70PR data can be wrong due to errors in IBM DIAG 204 instruction
    that were fixed with "Driver 15 - MCL H49560.003 or Driver 12 -     
    MCL H09168.004." The defect caused segments for some LCPUADDR to NOT
    be written, causing not only wrong engine counts, but the counts    
    were reversed in different system's TYPE70PR data.  LPAR A reported 
    LPARs B and C had 1 and 2 CP engines, but LPAR B reported LPAR B and
    C had 2 and 1 CP engines.  Incorrect values were shown in RMF CPU   
    Partition Data Report.                                              
 1. The IEF032I Step Termination Message has many fields that are in the
    SMF 30 records.  I've typed the MXG Variable name in lower case:

IV.   DB2 Technical Notes.                                              
 1. Text                                                                
V.   IMS Technical Notes.                                               
 1. IMS 13 APAR PI42904 now populates the IMS 56FA log record variable  
    TRANSACT with the value of the inputted CCTL/ODBA transaction ID or 
    Job ID, which was not populated when TLS was active.                
VI.  SAS Technical Notes.                                               
 2. Starting in SAS V9.2, the XPORT engine no longer supported the      
    TRANSCODE attribute, which protects character variables that        
    contain HEX values from being translated when moved between EBCDIC  
    and ASCII platforms (both ways). MXG assigns the TRANSCODE attribute
    to all $HEX. formatted variables. The XPORT engine also does not    
    support long variable names nor long dataset names.                 
    Using the XPORT engine with PROC COPY generated these error         
    messages executing under SAS 9.4:                                   
        NOTE: Copying PDB.TYPE70 to XPORT.TYPE70 (memtype=DATA).        
        WARNING: TRANSCODE suppression is not supported by the XPORT    
                 engine.  All the character variables will be added     
                 without the transcode suppression to the dataset       
        ERROR: The variable name SMF70CPA_RATIO is illegal for the      
               version 6 file XPORT.TYPE70.DATA.                        
        NOTE:  Set the VALIDVARNAME=V6 option to enable automatic       
               truncation of long variable names.                       
        ERROR: File XPORT.TYPE70.DATA has not been saved because copy   
               could not be completed.                                  
    You MUST use PROC CPORT/CIMPORT instead of the XPORT engine if the  
    MXG dataset has variables with the TRANSCODE=NOTRAN attribute, or   
    has variables with names greater than 8 characters, now common in   
    MXG datasets.   All examples that referenced XPORT engine will be   
 1. ASCII SAS does not accept slanted quotes, '60'x, instead expecting  
    the vertical quote, '27'x.  However, when I emailed code with the   
    vertical quote, in an HTML-format email, the vertical quote was     
    changed to a slanted quote, and the program failed with:            
      DATA; X='A'; IF X=`A` THEN PUT ' MATCHED '; RUN;                  
     ERROR 390-185: Expecting an relational or arithmetic operator.     
    And, in the actual log, on Windows, those slanted quotes were NOT   
    displayed by SAS 9.4 - they appeared to be vertical quotes in the   
    log window!

X.   Email notes.                                                       
 1. Text                                                                
XI.   Incompatibilities and Installation of MXG vv.yy.                  
 1. Incompatibilities introduced in MXG 33.11 (since MXG 32.32):        
    See CHANGES.

    in member INSTALL (separate sections for each platform, z/OS, WIN,  
    or *nix), with examples of common Errors/Warnings messages a new MXG
    user might encounter, and in member JCLINSTT for SAS V9.2 or member 
    JCLINSTW for WPS. INSTALL also shows how to read SMF data on PCs/nix
    using the FTP ACCESS METHOD.

 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 always identifies the actual version and release of     
 MXG Software that is contained in that library.                        
 The CHANGES selection on our homepage at            
 is always the most current information on MXG Software status,         
 and is frequently updated.                                             
 Important changes are also posted to the MXG-L ListServer, which is    
 also described by a selection on the homepage.  Please subscribe.      
 The actual code implementation of some changes in MXG SOURCLIB may be  
 different than described in the change text (which might have printed  
 only the critical part of the correction that need be made by users).  
 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.
