Generally, VSAM data sets (like sequential data sets) will be read sequentially from the first record to the last. You can use direct reads instead of sequential reads to skip around in the data set.
CICS does allow you to read in a reverse fashion by allowing EXEC CICS READPREV but this only applies to CICS.

This does not apply to normal COBOL Batch program, then how can we do this for batch? please guide.
