Yes, you can do with READ PREV command in CICS.

If you want to do in COBOL, you have to use your programming LOGIC.

Hi Priya,

I am not very sure of using the READ PREV command with Sequential files
as till date I have used this only for VSAM data sets.

Can you please elaborate more on how to use READ PREV with sequentail
files. I want to know how exactly it functions in case of sequential data sets.

regards,
David.

Use SORT. Pad a sequence number to each record and sort these records on the sequence number in descending order.

Can't do it. Try Assembler. Or FileAid copyback, then read that in COBOL.
