baskkarsubbian,

When you say files, I assume that you are reffering to VSAM files. You need to swap the entires in the FCT(file control table). Within the program you need to change the file opening ,reading, updating sections.

Hope this helps...

cheers

If he is the only one using these files then he can change the DDName to the different DSName with CEMT I FI(DDName) without changing his programs at all. He must have CEMT authorization to open/close/change.

Ya exactly it's a vsam file and i'm not clear about your answer to swap the files in the fct. Can you explain in detail if you have few minites for me .

Thanks in advance

All you had to do is try out the CEMT command. The results are:
I FI(DFHCSD)
STATUS: RESULTS - OVERTYPE TO MODIFY
Fil(DFHCSD ) Vsa Clo Ena Rea Upd Add Bro Del Sha
Dsn( TBASLO.DBT.TS22.DFHCSD.KSDS )

Close both datasets.
You can then just overtype the Dsn(......) of each dataset setting it to the Dsname you need.
Open both datasets.
