When we use the CA Endevor Software Manager program BSTCOPY to copy a PDSE load member, it seems as if the member is being changed physically. However, when copying a PDS, the source module and destination module are physically equal.
Can I use SuperCE utility to compare the changed load ?
Note that the footprints are not modified at all.
"The binder API does not have a function to 'copy a member'. Member copy is performed using the binder by using two other functions:
Referring to the SuperCE help - tutorial option 17.5 'Comparing load modules':
- ISPF compares the entire module, not only the executable code. This would include IDR data which would have compile and linkedit information, as well as other undocumented information for a program object (a load module in a PDSE library).
So it stands to reason that if the binder is used for the copy(by BSTCOPY with or without FASTCOPY) it would not be surprising that SuperCE finds differences.
CA PDSMAN has a compare utility that considers only the executable text - PDSM36
You can run it using this sample JCL:
//PDSM36 EXEC PGM=PDSM36,PARM='mbrname'
//PDSMRPT DD SYSOUT=*
//PDSMOLD DD DISP=SHR,DSN=library1
//PDSMNEW DD DISP=SHR,DSN=library2
Library1 and library2 are the libraries you need to compare
mbrname is the program object name.
You may use any other utility that allows to compare Load module similar to this CA PDSMAN feature.
