Is it possible to write an optimum cobol batch program for deleting records from a ksds vsam file? Environment is MVS(S390).
I have
1)a huge ksds indexed master file(Around 4000000 records).key is the first 4 characters.
eg:-
A001 Martin adress1-----
A002 Joe adress1-----
A007 Jeff adress1-----
A008 Jones adress1-----
A016 Linda adress1-----

2)a sequential file with records(keys) to be deteted from the master file(Around 4000 records)

A002
A008

Output desired is

A001 Martin adress1-----
A007 Jeff adress1-----
A016 Linda adress1-----

back into the same ksds file and I cannot use a JCl for this.

Please let me know the syntax of vsam statements for this in a cobol batch program, if at all this is possible.

Thanks in advance,

Thanks Kolusu.

Sorry for bothering you for this simple one. I bought a book on vsam by Jay Ranade and it was over in half an hour.
