CA Datacom support previously provided a sample program source called DBSXCPR3 on the Recommended Reading/Samples part of the product website. This document provides an updated version for IBM Enterprise COBOL compiler version 3.4 and higher, and with more selection options. As of February, 2020, this has been tested with the compiler version 3.4 up through 6.3 using the JCL as it is delivered.

This program reads the CA Datacom Recovery File (RXX) and produces a report of the records on it. The report can be filtered by multiple selection criteria. This sample program will not manipulate the RXX records, but will only summarize or show details of the records there according to the filter criteria. This is meant to be a model upon which you can build your own RXX query program if you wish.

There is a file attached to this article that contains the components necessary to compile the program to read the CA Datacom RXX file. These components can be found in the PDS created from the attached file, which has been tersed. You should upload the tersed file from your PC to the mainframe as a BINary file, FB, LRECL=1024, BLKSIZE=27648, and then use JCL like the one below to recreate the PDS from the uploaded tersed file. Note that all members have been set to ISPF version 2.0 (as of 25 February, 2020).

// SET TERSFL=<<Your downloaded tersed file (attached below)
// SET OUTPDS=<<A New PDS filename for the utilities
//X01      DD  DSN=&OUTPDS,
//             DISP=(MOD,DELETE,DELETE),UNIT=3390,SPACE=(TRK,1)
//* - - - - - -C- - - - - - - - - - - - - - - - - - - - - - - - - - -7-
//             UNIT=3390,STORCLAS=TSO,DSORG=PO,SPACE=(CYL,(1,1,5),RLSE)

Here are the members in the PDS that will be built from the tersed file:

Note that compiler options are in the COBOL source, and special binder options and commands are in the JCL source.

This program reads the CA Datacom Recovery File (RXX) and produces a report of the records on it. The report can be filtered by entering various selection criteria in the SYSIN.                                                                                                     
There are multiple filters that can be selected in the SYSIN and one report type selection. Only those filters that are desired need to be entered; the rest will use the default. If duplicate functions are entered, the last one entered will take precedence over the others. Also, in the filters, the "X..." filter will take precedence over the root selection filter. For example if specifying these:

USER1   MYUSERID                                          
USER2   ANOTHER1                                        
USER3   ONEMORE                                          
XUSER1  ANOTHER1                                          

only MYUSERID and ONEMORE are selected; ANOTHER1 was excluded by the XUSER# function.

These are the functions that are allowed (commands are in col 1-7, data starts in col 9). Note that on any command, columns 30-80 are not processed, and can be used for comments on a specific entry.

COMMENT            - Any text can be entered on this line   
                     Can also use * in Col 1                
RPTTYPE xxx        - Generate a report with one of these:   
  DET              - Detail line report                     
  SC               - Sum by CA Datacom Command              
  SD, DT, DTC      - Sum by DBID (+Table) (+Command)        
  SJ               - Sum by Jobname                         
  SJD, SJDT, SJDTC - Sum by Job  +DBID (+Table) (+Command)  
  SU               - Sum by User ID                         
  SUD, SUDT, SUDTC - Sum by User +DBID (+Table) (+Command)  
DISPLAY            - Display before-rec and workarea        
LIMIT   #######    - 7 Digits, Max # records to read        
ORDER   OOOOO      - 5 Chars to order by COUNT or sum KEY   
TIMEBEG CCYYMMDDHHMMSS - Length 14 Digits, Date/Time values 
TIMEEND CCYYMMDDHHMMSS - Length 14 Digits  are inclusive    
Commands below can create four filters each, using suffixes 
of 1, 2, 3, or 4, except USER# which can be 1 through 8.
