File Manager for z/OS Batch ENHANCEMENTS

With service recently made available in 4th quarter 2019, File Manager for z/OS provides several batch report enhancements. You can now split batch report sections across different DDs, rather than having all your output go to SYSPRINT, and certain batch reports now provide additional data set information for relevant input and output files.
​

File Manager now also supports two new DDs, FMIN and FMNPRINT. When allocated in a batch job step, File Manager will use FMIN rather than SYSIN, and FMNPRINT rather than SYSPRINT.

Batch report output by default goes to SYSPRINT (or FMNPRINT). Now sections of the output can be directed to specific DDs as follows:
              FMNROPT           File Manager active options
              FMNRPRM          $$FILEM command parameters and return codes
              FMNRPRC           REXX procedure statements read from SYSIN
              FMNREPT            Command reports and return codes
              FMNRSUM          TALLY summary report

​When the FMNRPRM or the FMNREPT DD is used, new message FMNBA108 is now generated to indicate the return code of each File Manager command executed by the batch job step. For example:
          $$FILEM DSP,                                                                  
          $$FILEM INPUT=DDIN,                                                            
          $$FILEM PROC=*                                                                 
FMNBA108 Function DSP Return Code 4

In addition, batch reports now provide data set information for relevant input and output files. When running the PRINT, COPY, COMPARE and FIND/CHANGE commands, File Manager will provide additional data set information.

The additional data set information is contingent of a new DSINFO option, which by default is set to NO. Like other File Manager options, DSINFO can be set system-wide via the FMN0POPT module.

Alternatively, each batch job step can use the $$FILEM SET command to set the DSINFO option. For example:

                 $$FILEM SET DSINFO=YES

When set to YES, File manager provides the DSORG, RECFM, LRECL and BLKSIZE for non-VSAM data sets, and the average record length, maximum record length, key offset, key length and reuse for VSAM files. For example, when running a COMPARE, or DSM command:
              IBM File Manager for z/OS                                                   
              * * * * Formatted comparison with one-to-one synchronization               
              * * New data set: KEEPER.FM.KSDS.NOREUSE.SHR1                              
              * *               Device DD95, 3390, VOLSER=D$US00, VSAM KSDS              
              * *               Avg Rec 21, Max Rec 80, Key Offset 0, Key Len 21, Reuse NO
              * *               using template FMN.TEMPLATE(TEST0102)                    
              * * Old data set: FMN.FMDATA                                               
              * *               Device DDBE, 3390, VOLSER=D$FM07                         
              * *               DSORG  PS, RECFM FB, LRECL 80 BLKSIZE 27920              
              * *               using template FMN.TEMPLATE(TEST0102)
