Hi,
Is it possible to initialize a IMS database from the cobol program,deleting all the previously existing records?. If yes, then how to do that?

Thanks,
Arasan

IMS database is simply a VSAM file. So if you delete and redefine using IDCAMS utility all you the existing data wll be loast and you can proceed to load the information afresh by INSERT calls.

If you want to initialize the records, then you have to have the following things in the loop

GHN with unqualified SSA and REPL call after initializing the fields of the I/O area untill the end of database (GB status code)
