Pass values b/w JCL and Cobol

diwa_thilak · Posted: Sun Oct 22, 2006 5:03 pm

Hi all,

I need to pass a set of values from JCL to cobol.
ie in my JCL i will pass the values using SYSIN Parameter.

//SYSIN DD *
0459
0763
1020
/*

Now my cobol programs needs to read these 3 values and needs to do processing.

The number of parameters varies each time. how can we do this ? Can you explain me with an example.

Any suggestions. Or by using files can we improve the performance.

Thanks,
Diwakar .D

Diwakar,

just treat it as any other file. that is all it is. code a SELECT and FD statements, OPEN/READ/CLOSE. The reference name in the SELECT statement is SYSIN.

Or, if you want to use ACCEPT, code an EOF rec in the input stream. You can use "END" or any other char(s) that you're sure won't appear as valid IP. Then check for it after every ACCEPT to stop the loop.

In this case you you don't need OPEN/CLOSE.

There are bennies/ouches that come w/each. It's your choice.

Hi Jack,

Could you please give me an example for the first scenario. How accept parameter reads multiple parameters from JCL.

Thanks,

Where v1,V2&V3-are variables.
