Hi ,

I have the following step in a Proc

//IF02 IF (RC LE 4 AND ABEND=FALSE) THEN

execute some steps

//els ELSE
execute some steps

//ends ENDIF

Lets say my Jcl i XXX and my Proc name is YYY

Can i overrid my If statement from the jcl to say
IF (RC LE 8 AND ABEND=FALSE) THEN

Please Advice .

What is wrong with trying it yourself and then asking if you have problems.

ex : Jobname.Stepname new condition

Procname.Stepname new condition

Nothing worked

Not sure that you can override IF/THEN/ELSE if it is in a PROC

Hello,

Which is why I NEVER use them within a PROC.

This is probably yet another case of bad planning / lack of testing.

What I have done to make this work in a PROC is make the condition on the IF statement a Symbolic.

The default is set in the Proc, and it can be overriden from the Job. This works really nice. It just requires you plan ahead.

Here is an example (just a snippet):

I couldn't remember if I included this in the JCL parser I wrote but symbolic replacement in IF statement is supported with the following caveat (JCL Ref 17-9). This is from the 390 version, I find it much more informative than the ZOS version (apparently someone decided to edit out or obfuscate a lot of useful information in the ZOS version of the JCL Reference).
