I want to create a cobol program fro the below requirement..

Reqmt: Input file has 3 types of Accounts. We want to segregate and write these 3 types of accounts to 3 different files. if any one of the o/p file was empty . it should not create even an empty file(this case should be handled in cobol program itself).

Can any one help me how to resolve this problem.

Unless the files are dynamically allocated by the COBOL program,
(output for a file is determined as yes)
you will need to have a succession of 3 IEFBR14's,
each referencing with a DISP=(old,delete,delete) one of the files,
and having a double
[e.g. (rc=1)or(rc=4)] (syntax found in JCL reference manual and the users guide - great write-up)
COND CODE= parm for the EXEC parm,
or an IF,
controlled by the Return-code of the COBOL program.

many topics here in the forum.

because I consider dynamic file allocation in COBOL,
something that i feel application programmers should not do
you can search yourself in this forum. lots of topics and solutions.

if you are an application programmer, you will have to dig,
if you are a systems type, then the info is also there.

you are lucky,
my girlfriend is showing up soon
so, I will refrain from making any negative remarks,
though it is obvious that I want to make some.
