Parm sending the wrong value.

Hello Everyone,

I am passing a string of 7 chars using PARM in my JCL to my cobol pgm. I have declared the varible in Linkage section. However I am getting my output not as expected. There are two spaces in my output which is ruining the output. I have attached the codes. Please take a look and suggest.

Thanks,

Did You read the docs carefully ???
the length should come before the string like this ...

as usual I hit enter too quickly..

why blame others?

jcl as far as I can remember never made mistakes in passing parms

programmers usually made mistakes in retrieving them

Move LS-VAR-LENGTH before LS-VAR-TEXT.

Validate LS-VAR-LENGTH and use it as the reference modification length when addressing LS-VAR-TEXT.

FWIW, define LS-VAR-TEXT as PIC X(100), which is the maximum length for a pass parm from JCL and always use LS-VAR-LENGTH as the reference modification length.

If you address LS-VAR-TEXT without using the reference modification length, you run the risk of raising a S0C4 Protection Exception.

HTH....

Regards,

Bill

Thanks Enrico & Bill,

I have fixed the prob and its working fine now....Just wanted to confirm:

The parm can pass a length of 100 chars and the first 2 of the data that reach the application pgm contains the length of the char which has been passed. Am I correct?

Thanks,
Anjani.
