    of good information about MVS, and especially                       
    about the history of MVS measurement. We are                        
    pleased to be able to share his work with you.

I.  MXG SOFTWARE VERSION 6.6 "CRITICAL CHANGES".                        
                                                                        
  MXG Version 6.6, shipped Jan 21, 1989, has several errors which may   
  require your immediate attention.  At the beginning of the Change Log 
  section of this newsletter are listed the known "Critical Changes".   
  YOU MUST READ THAT SECTION IMMEDIATELY.                               
                                                                        
  MXG IMS log processing (TYPEIMS) has been in production at a number of
  sites with no problems, yet other users have definitely encountered a 
  host of problems, and have provided us with their fixes. We are still 
  validating their discoveries (which are too extensive to distribute in
  this newsletter).  We know that IMS 1.3 data is not correctly handled 
  by MXG 6.6, and it appears that some variables are missing and some   
  time stamps are wrong for some transactions in IMS systems which have 
  Wait-For-Input and similar environments.  Transaction counts and the  
  CPU and DL/I resources seem to be always correct, but response time   
  measurements are occasionally wrong, LTERM is sometimes blank, etc.   
  We will provide these IMS fixes when validated via a pre-release of   
  MXG that will be available (only upon request) in second quarter 1989.
  If you use TYPEIMS for log processing, write us, call (214-351-1966), 
  fax (214-350-3694), (or overseas contact your local SAS office), and  
  request to be placed on the "IMS FIX LIST".

   You MUST read each Change description below to determine if a Change 
   will impact your installation. For each impacting change, you should 
   also read any comments in the beginning of the source members that   
   are listed under the change number. Notes, comments, and last minute 
   documentation are sometimes found in comments in the source members.

 Critical changes (i.e., those that avoid error conditions) are marked  
 by  FIX:  following the discussion.   If you use the member listed in  
 a critical change, you must install the FIX.                           
                                                                        
  The following changes are critical:

 You can make these changes directly in the MXG.SOURCLIB library.       
                                                                        
 Alternatively, you may wish to create a new MXG.CHANGLIB library to    
 hold any changes distributed (as are these) in printed form. You would 
 store the changed members in MXG.CHANGLIB (which would be concatenated 
 between your MXG.USERID library and our MXG.SOURCLIB library) until    
 you receive a replacement version of MXG, at which time you must then  
 delete all members in the MXG.CHANGLIB library.
