Hi,
There are 3 programs: 1, 2 and 3.
Step 1 executes program 1.
Step 2 executes programs 2 & 3.
There is a variable called as

If Option = A, Step I should get executed, else Step 2 should get executed. How do I code this in a JCL using an If-then-else statement? Is there any other method available?

prasanth_thavva,
You can only CHECK numeric values within a IFTHEN in JCL.

You'll need a program to check the value of OPTION and set a RETURN-CODE value appropriately. Then:
| Code: |
//* CHECK VALUE OF OPTION. IF IT IS 'A', THEN SET RC=0. ELSE,
//* SET RC=4.
//CHECK EXEC PGM=XXXX,PARM='&OPTION'
//*
// IF (CHECK.RC=0) THEN
//STEP1 EXEC PGM=PROG1
// ELSE
//STEP2 EXEC PGM=PROG2
// ENDIF

IF-THEN-ELSE is to do with condition code checking, nothing else. You would need a 4th program that would run first - read the otion and set a return code accordingly. Your IF can then use this RC. I presume your 'step' 2 actually executes a procedure consisting of 2 program steps - a step can only execute ione program.

Hi SuperK
Could you please let me know after reading the value of OPTION in the program, how to set the RETURN-CODE value appropriately.
Thanks & Regards,
kirank. |

That is a programming question, a new thread and not JCL.
But, seeing as it is now here: Which language are you using because setting the return code varies from language to language?

Hi all,
I have a suggestion to control step-execution:

Step 1 executes program 1.
Step 2 executes programs 2 & 3.
There is a variable called as

If you did that - why not just have one file? Put data into it if OPTION is A otherwise just open/close it. IDCAMS reads it and it is either populated or empty and the return code is set accordingly. But you still have to have a program that reads the option so why complicate things with extra files? Just set the RC dependent on the option value.
