You can not use VSAM-ESDS with AIX in Cobol Batch Program you can use only in CICS-Cobol Program

I believe AIX is built on either RBA or RRA (Relative byte address or relative record address) so if you did a read using these, you should be able to 'randomly' read the file. I believe you would also have to request something like skip sequential processing.

Basically the previous answers have all hit around the issue. My understanding is that you should use IMPORT and EXPORT if you want to take a dataset that is in one catalog and get it into another catalog. REPRO is fine for creating a backup copy.
