  This member will contain the change status (i.e., last change number) 
  when the library was shipped to you.  It will be updated (by complete 
  replacement) when you receive MXG Support Subscription Updates (SSU)  
  from Merrill Consultants, 10717 Cromwell Drive, Dallas Tx 75229,      
  214-351-1966.  Between SSU's, fixes will be provided as "Temporary    
  Changes" in printed form.  You should update this member after you    
  install any temporary changes.                                        
                                                                        
                                                                        
                                                                        
EARLY SHIPMENT CHANGES                                                  
                                                                        
Listed below  are all of the changes were applied to the early shipment 
software (Nov 1, 1983 to Aug 15, 1984). These changes have already been 
made to this library, but are included here for information.            
                                                                        
Change 00.50   PERFGRP was removed from keep list for macro _PDB30_1.   
BUILDPDB      For Started Tasks and TSO Users,   the value of PERFGRP   
BUILDPD3      in the subtype 1 type 30 record   is zero, which caused   
Aug  8, 1984  PERFGRP in STEPS data set   to be wrong if the step was   
              TYPETASK=STC or TSU and   a subtype 1 record was found.   
              This is a circumvention, until the value of  PERFGRP in   
              the subtype 1 (Job Init) is corrected by IBM.             
   Thanks to Georg Simon, Prudential, USA.                              
                                                                        
Change 00.49   Advised that variable RECORDS can have a negative value. 
VMAC64        Altered the input format from PIB to IB to handle these   
Aug  6, 1984  potential negative values,  but have not yet determined   
              the intrepretation of these negative values.              
   Thanks to Geoff Neal, Health Insurance Comm., AUSTRALIA              
                                                                        
Change 00.48   Created member to process CICS Monitor Facility records  
TYPE110J      which were written to a journal file, as described in     
Aug  6, 1984  the Chapter on CICS.                                      
   Thanks to Debby Blackey, Fidelity Savings, USA.                      
                                                                        
Change 00.47   Corrected spelling errors and inconsistencies in labels  
DOC           which the super proofreaders at SAS found in reading the  
Aug  6, 1984  text at the galley stage.                                 
   Thanks to ???, SAS proofreaders, USA.                                
                                                                        
Change 00.46   Corrected spelling errors in comments in describing the  
BUILDPDB      SPIN logic and added a comment line where default number  
Aug  6, 1984  of days to spin is set.                                   
   Thanks to Patricia McKenzie, B.C. Systems, CANADA.                   
                                                                        
Change 00.45   Test to define DEVICE variable expanded to include JES3  
VMAC6         printers (which have PRTnnnnn format for OUTDEVCE value.  
Aug  6, 1984                                                            
   Thanks to Paul Walker, IBM, USA.                                     
                                                                        
Change 00.44   CPU busy is now zeroed and CPUWAITM  set to the duration 
VMAC7072      of the interval if either the CPU was  offline at the end 
Aug  6, 1984  of interval,  or for an interval during which the CPU was 
              varied on or off line.    Early shipment code only tested 
              for offline at end of interval.                           
   Thanks to Patricia McKenzie, B.C. Systems, CANADA.                   
                                                                        
Change 00.43   A nit. IMACUCB in  the comments  was changed to VMACUCB. 
VMACUCB       Even nits require a change, and thus are documented here. 
Aug  6, 1984 Thanks for my primary nitpicker!                           
   Thanks to Chuck Hopf, Computer Language Research (FASTAX), USA.      
                                                                        
Change 00.42   The page fault rate variables (SYSPFR  for system areas, 
VMAC71        and LCLPFR for local area) were slightly in error. SYSPFR 
Aug  6, 1984  included LPAGINS twice  (because PVTCAIN already includes 
              LPAGINS), which caused LCLPFR to be smaller by a LPAGINS. 
              Variables  PFRATE and PAGING  are replicated as variables 
              PTR and DPR  for report program compatability. PFRATE and 
              PAGING existed  before MVS/SE1 introduced  PTR and DPR as 
              "Happy Value" SRM  measures.  Note there is a significant 
              change in  TYPE71 in  MXG when compared with the original 
              MG code.   In MXG the paging variables are now calculated 
              as rates per second,  whereas the original code variables 
              contained total pages during the RMF interval.   You will 
              have to check report  programs which  use TYPE71 data and 
              will likely need to modify your SAS program.              
   Thanks to Wayne Lauck, Central Data Processing, USA.                 
                                                                        
Change 00.41   The variable names starting with LOG.... were changed to 
ANALNPA       begin with NPA.... to agree with the names in TYPE38.     
Aug  6, 1984                                                            
                                                                        
Change 00.40   Format for timestamps in subtype 1 and 2 records was not 
VMAC90        correct in SMF manual; documentation APAR OZ81250 will be 
Aug  6, 1984  issued by IBM to correct the manual. MXG was corrected to 
              decode fields as data actually exists.  Structure of code 
              was altered to prevent possible errors when no active SMF 
              data set is given in a type 90 record,  and variable BITS 
              was assigned format $HEX64.                               
   Thanks to Paul Walker, IBM, USA.                                     
                                                                        
Change 00.39   Variable IPLTIME, with length 8, was added to the LENGTH 
VMAC0         statement. Timestamp variable must be length 8 to prevent 
May 31, 1984  loss of minutes and seconds of precision.                 
   Thanks to Paul Walker, IBM, USA.                                     
                                                                        
Change 00.38   The error handling of CICS CMF records introduced in ES23
VMAC110       creates *ERROR.VMAC110.1 for all dictionary entries.  The 
May 28, 1984  dictionary entry is identifiable by the value of zero for 
              variable  MCTSSDID in the second line after the  "SECTION 
              HEADER DESCRIPTOR."  The  error message  has no effect on 
              the data, but is eliminated by changing the test for this 
              error message from                                        
                  OR SECTLLBB LT TEMPBYTE                               
              to                                                        
                  OR (SECTLLBB LT TEMPBYTE AND MCTSSDID NE 0)           
                                                                        
              Additionally, CICS 1.6.1 has some initial data  values in 
              error which cause IRESPTM, the internal response time, to 
              be very negative. Variable WTTCIOCN is 65535 and WTTCIOTM 
              is completely invalid. In all cases observed so far,  the 
              value of TASERRFG was non zero for these values, and thus 
              the calculation of IRESPTM is now only calculated as:     
                                                                        
                  IF TASERRFG EQ 0 THEN IRESPTM=ELAPSTM-WTTCIOTM;       
                                                                        
              There may in fact be PTFs which have not been applied  at 
              my CICS 1.6.1 test site which cause these data values. It 
              is still wise to  calculate the  response only when it is 
              valid to do so!                                           
                                                                        
Change 00.37   TWO NEW VALUES WERE ADDED TO THE MG110ER FORMAT,  DUE TO 
FORMATS       new error flag values appearing in CICS 1.6.1:            
May 28, 1984    00X='  '                                                
                50X='50X:INVALID CLOCK AND INTERNAL ERROR'              
                OTHER='OTHER ERROR'                                     
                                                                        
Change 00.36   VARIABLE ALLOCATN IS REPLACED BY THREE ONE-BYTE VARIABLES
VMAC25        describing how this allocation was made: ALOCBYDD ('Y' by 
May 25, 1984  DD, 'N' for dynamic), ALOCATLG ('Y' if Catalog used,  'N' 
              if not),  and ALOCAUTO ('Y' if automatic, 'N' if manual). 
   Thanks to Paul Walker, IBM, USA.                                     
                                                                        
Change 00.35   STATEMENT SWAPRATE=SWAPRATE*INVTIME; WAS REPEATED IN BOTH
VMAC71        the MVS/370 and MVS/XA segments. The second occurrence was
May 25, 1984  deleted in both segments.                                 
   Thanks to Jim Trenkle, Safeway, USA.                                 
                                                                        
Change 00.34   VARIABLE TYPETASK UNDER JES3 CONTAINS A ZERO RATHER THAN 
VMAC26J3      blank for the fourth position. A blank is now forced into 
May 25, 1984  the fourth position.  It was not shortened to three-bytes 
              to maintain consistency with TYPETASK in other data sets. 
   Thanks to Jim Trenkle, Safeway, USA.                                 
                                                                        
Change 00.33   WORKLOAD VARIABLES WHICH WERE INCORRECTLY CALCULATED WERE
RMFINTRV      corrected as described in NEWSLETTER Volume I Number Two. 
May 25, 1984                                                            
                                                                        
Change 00.32   VARIABLE JOBID WAS  REMOVED FROM KEEP LIST.  IT HAD BEEN 
VMAC26J3      replaced by variables TYPETASK and JESNR and should never 
May 20, 1984  have appeared in the KEEP statement.                      
   Thanks to Paul Walker, IBM, USA.                                     
                                                                        
Change 00.31   NEW MODULE, FOR TYPE 110 CICS RECORD WHICH SETS THE SIZE 
IMACICUS      of the USERCHAR variable in CICSTRAN. If you want account 
May 20, 1984  data on CICS transactions,  you must use the optional user
              character field. Default is for a one-byte field. See  the
              discussion in the member, and more in Newsletter #2.      
                                                                        
Change 00.30   NEW MODULE, FOR JES3. IT BUILDS THE PDB JUST AS BUILDPDB

May 10, 1984  be incorrectly documented in the SMF manual,  resulting in
              a STOPOVER Abend.   After reaching Level II,  the code was
              fixed and a document APAR from IBM can be expected. At the
              same time another  of my errors was corrected.

Change 00.25   INVALID TYPE 30 RECORDS HAVE BEEN CREATED BY MVS WITH THE
VMAC30        'triplets' (the three values of offset, length, and number
Apr 26, 1984  of relocatable sections) overlaid with blanks. This caused
              a STOPOVER abend when the blanks were read in as PIB4! The
              offset value plus length of the relocatable section is now
              compared  with  the  LENGTH of the record, and the invalid
              records will be printed in hex on the log.                
                                                                        
Change 00.24   OCCASIONALLY, THE NUMBER OF SAMPLES NRSAMPLE WILL BE ZERO
VMAC7072      in  a  type  70 record.  It appears this can happen if the
Apr 26, 1984  operator issues a Modify command at startup,  although  it
              may  be  due  to other phenomena.  The records have a very
              short duration, and have  little  other  effect,  but  the
              division  by  zero caused an abend.  This change tests for
              nonzero  value of NRSAMPLE before division.  Additionally,
              the divisions by CPUCOEFF and SRBCOEFF are also now tested
              for nonzero  for CPUTCBTM and CPUSRBTM in TYPE72 data set.
              Finally, the error messages for a missing value of SU_SEC,
              (the service units per CPU second) were cleaned up.

   Thanks to ???, SAS proofreaders, USA.                                
                                                                        
Change 00.09   THE LENGTH VALUE USED TO READ IN THE SIGNON VARIABLE     
VMAC4789      includes the two bytes of length itself, causing a        
Mar 31, 1984  STOPOVER abend. Code restructured to subtract two from    
              length before executing the $VARYING60. INPUT statement.  
              Additionally, the offset @41 in ID=49 code was typographic
              and should be @51.

Change 00.08   RMV VERSION 3.2.1 CHANGED RMF VERSION FROM 2 BYTE EBCDIC 
VMAC7072      to a 2 byte packed decimal. Now version can print as 321  
VMAC73        whereas before it was limited to 32.

Change 00.07   SUPPORT FOR RMF VERSION 3 RELEASE 2 MODIFICATION LEVEL 1 
VMAC78        installed. RMF 3.2 added TYPE78VS, TYPE78SP and TYPE78    
Feb  4, 1984  data sets and 3.2.1 added support for 4381 processor      
              types. Only TYPE78VS data set has actually been           
              validated.                                                
                                                                        
Change 00.06   IMPROVED ERROR HANDLING FOR INVALID RECORDS NOW PROVIDES 
VMAC110       diagnostic messages and a dump of the type 110 record when
Feb  4, 1984  invalid data is encounterd. This will eliminate STOPOVER  
               abends in type 110.

Change 00.02   SEVERAL VARIABLES WERE NOT SET TO MISSING WHEN NRSTCPS,  
VMAC73        the number of samples, was zero, and thus had the value of
Dec 23, 1983  value of the previous calculation.
