This is an old REXX for extracting some VSAM information using CSI. If you want to add more fields then you will have to refer to the manual below for field names and also change the code accordingly.
Click HERE to see the manual for using CSI. Appendix C.
You may also want to investigate DCOLLECT records as a source of information instead.
This was created for batch execution with CATIN DD * supplying the VSAM clusters to be interrogated. It Accepts full * ** % and %% filtering capabilities for CATIN.
Good luck ......................
