How to Override DD based on RC of previous step

HI,

I have to override a DD statement based on the RC of previous step STEP1. If RC of Step 1 is 0 then the (0) version of the GDG needs to be used and if RC of step 1 is 1 then the (+1) version of the GDG needs to be used.

Regards,
Ram.

Look at two identical steps controlled by IF/THEn/ELSE one using the 0 and one the +1.

IBM Manuals at the top of the page - JCL reference, and there you go.

HI,

Assume PROC1 having many steps among them STEP1 is one step name .STEP1 having many DD statements.If we want to override DD statement of STEP1. we follow below mention procedure.............

//JOBCARD
//STEP1 EXEC PGM=PRG1
//DD1 DD DSN = A.B.C
//STEP2 EXEC PGM =PROC1, COND=(0,<>,STEP1)
//PROC1.STEP1.DD1 DD DSN='GDG(0)
//STEP3 DD PGM=PROC1,COND=(1,EQ,STEP1)
// PROC1.STEP1.DD1 DD DSN='GDG(1)'
//

Please correct me if i am wrong...............

You are WRONG
Have you actually tested that code ?

PGM= PROC1
3 level overrides
<> in condition checking
'GDG(1)' (1) what - would that be a + or perhaps a -

Do you have access to a JCL manual - if so - start reading it NOW

Hello,

At the top of the page is a link to "IBM Manuals".

Among them are the JCL documentation.
