...or it can be a load module containing multiple programs (composite).

Hello,

The EXEC statement is the "new step" - it is the way the system knows the end of one step and the beginning of the next.

Do you have a requirement we might offer suggestions for, or is the question for learning?

yeah..I'll follow Dick words, Please let us know why there is a requirement to run more than one pgm in a single step.

If it's a learnig process then I'll say that we cant have this type of code in JCL/s

1. //JOBCARD
//step1 EXEC PGM=PGM1, PGM2
//steplib

2. //JOBCARD
//step1 EXEC PGM=PGM1, PGM=PGM2
//steplib

3. //JOBCARD
//step1 EXEC PGM=PGM1
//step2 EXEC PGM=PGM2

You'll get a JCL syntax err for all the above codes.

Anuj,

Hello,

#3 is ok as long as pgm1 and pgm2 are in the linklist - it not, it won't be a jcl error - it should be an 806 abend as there is no steplib or joblib.

Hi,

I tried the following at my shop, (in CHGMAN environment)

//STEP016 EXEC PGM=PGM1,REGION=4096K
//STEP017 EXEC PGM=PGM2,REGION=4096K
//STEPLIB DD DSN=CHGMAN.PKG.LOD,
// DISP=SHR
// DD DSN=TEST-REGION.IPCW.PROD.PGMLIB,
// DISP=SHR
// DD DSN=TEST-REGION.IPCW.PROD.LINKLIB,
// DISP=SHR

when I do JEM, got the following JCL err msg:

*** ERROR SUMMARY AND COUNTS *** JEM 6.2.7A 04/26/2007 06:04:08
0 ADVISORY LEVEL
0 WARNING LEVEL
1 ERROR LEVEL
1 TOTAL ISSUED 0 SUPPRESSED.
THE HIGHEST SEVERITY CODE ENCOUNTERED WAS 08.
LABEL SV MSG.NO. ERROR MESSAGE
-------- -- -------- ------------------------------------------------
.JAAA 8 DSS2050E - PROGRAM "PGM1 " NOT FOUND

If I ignore the above msg & SUBmits the JOB, then I'll get ABEND S806.I I think you wanted to say this only.

Still, if I get the above message, should not it be cosidered as JCL err at first place?
& yeah programs PGM1, PGM2 are development pgms, they are not utility pgms such as SORT etc.

Please clarify.

//stepname EXEC Procname like this

Put all your steps in the proc you are calling In the above example put all your steps in the proc you are calling.

Then when the JCL executes that proc it will open that proc and will execute all the steps in the proc.

But here the constraint is you need to code the Proc as follows

//Procname PROC SFX=P,
// GEN='(+1)', These are the optional ones you may code or you can skip. Because those are symbolic parameters I have used in my proc so I coded if you don't need it no need to code it.
*---------------------*
Start Coding the Steps you wan to execute.
//Step name EXEC PGM=Pgm-Name

Hence you have executed multiple steps in a single step

What do you say Dinesh?

Please let me know any body if I told any thing wrong?

I am sure from my side becuase it is implemented and it is now running currently in production.

Thank You,
Amar

Amar,
It looks like you are executing a procedure, not a program, inside the procedure there are multiple steps. This is a very common scenario, I don't consider this as executing multiple programs in one step.

Hello dick scherrer

I am not pointing out any body in this message. I didnt point out also if you read my message posted earlier.

But you are pointing out my mistake that I have wrong wording.

if i gave wrong solution then you would have told me that "That won;t meet the requirement"

Again you are telling like its not a good idea and as far as I know there is no good and bad , every thing is the way we think and understand it perfectly.

I didnt use improper wording. I just posted my idea. If it is wrong or my understanding of the requirement is wrong and if I hurted any body I am sorry all

Thank you
Amar
