What is the use of PARMIN DD * while executing a DB2 program using IKJEFT01. Is it for passiing values to program? Can anyone explain it's usage?

Padma,

I see no reference to //PARMIN DD * in relation to IKJEFT01.

Can you please give more information as to where you have run across this? Give code example if you can. Thanks,

Dave

Hi,

I have come across a Cobol - Db2 Jcl where PARMIN DD * is coded just like SYSIN DD * and passed values thrrough it. I think it is not restricted in using with IKJEFT01 and we can use it in a normal JCL. I would like to know it's coding purpose in detail.

Thanks
padma.

padma_prakasam,

You'll have to look at the program that the PARMIN is coded. Sounds like it is simply a flat sequential file that the program uses to determine how/what the program is to process.

As am example, in a program that may produce reports for a large store chain of stores sales, the PARMIN may contain a list of store numbers to process.

There is no single simple answer to what the PARMIN file is. The answer is in the program.
