VSAM-ESDS-AIX
When its not possible to read ESDS file randomly through COBOL program then what is the use of creating AIX for that file? If reading that file randomly is possible then plz give me the details. I tried but without success.

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.

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.

The length of rec1 is 6 bytes but the code is wrong. You can't redefine 01 level field with 02 level field. Redefined and redefining variables should be at the same level.If your code looks like t...
