JCL SET WITH IF not working

Based on a return code from a Particular Proc step am trying to decide a dataset qualifier in the next proc step as follows:

Job step1 :
PS1
PS2 : RC = 0
PS3
PS4

Have given the following SET command as far as :
//JSET1 IF (JS1.PS2.RC = 0) THEN
// SET PPGM3=ABCD
//JSET1EL ELSE
// SET PPGM3=EFGH
//JSET1EN END IF

Job step2 :
PS1
PS2 : Where the dataset is being used, as XXXX.YYY.&PPGM3..FILE in DISP=SHR
PS3
PS4

When JS1.PS2.RC gives 0 , as per the JCL it should give a value 'ABCD' to PPGM3 but it is always giving a value of 'EFGH' instead, irrespective of what is the value of JS1.PS2.RC.

The symbolic varaiable has not been in the proc but has not been assigned any value in the procedure.

The IF THEN ELSE ENDIF structure can only be used to control the execution of steps. The &PPGM3 is resolved at the time the jcl is submitted before any steps are executed. Set up two PS2 steps (PS2A AND PS2B) one with each version of the dsn and use the IF THEN ELSE ENDIF structure to control which one will be executed.

Hello,

Instead of trying to determine what we need to see, you should post all of the relevant info.

Post your jcl as well as the expanded jcl from an execution.

The set statement is processed unconditionally when the jcl is interpreted before any steps are executed. If you have a job stream with a set at the beginning and another set in the middle for the same variable but a different value then that parameter will have a different value in different steps.
