JCL to build multiple jcl's using a template

Postby Surabhi » Tue Nov 08, 2016 11:41 am

Hi All,

I have a requirement to build multiple jcl's using a template.
I have a PDS with almost 50 members, what i need to do is build a template for the jcl and replace just the member name in the JCL template, so that my original jcl can build multiple jcl's.
I have the template ready with me. Can some one please guide me how can i build multiple JCL's .

Thank you.

Hello,

A few queries:
a. Once the member name is overridden in 'the template', what do you want to do with it, before moving onto the next member?
b. Can you show us the template?

Depending upon your programming proficiency, choose any of the below options:
a. REXX - A small exec which will read the member names from the PDS containing your member and pad the member name as a symbolic to the 'template' which will be coded in REXX with QUEUE command; this can be routed to INTRDR using ISPF EDIT macro- SUBMIT. Look for 'how to get member list from PDS using REXX', quite a lot of examples here.
b. Using *SORT - Code your template using 'OUTFIL BUILD' and pass the member name of each member of your PDS using SYMNAMES; route the output as you may choose.
c. COBOL - Similar logic as REXX, though you'd need to be proficient in calling the ISPF services in COBOL, again, quite a few examples are available.
d. (I'd prefer this) ISPF File-Tailoring - This has been out there for a while and is really good once you get a hang of it. Refer this link for starters, once you've learnt how to use these services, you can build on this powerful tool.
--- and more options.

The choice and further code will again depend upon the primary questions.

Hi Aki88,

Once the member name is overridden in the template , it will move to the next member and once all the members are done i need to submit those jobs.
Can this be done using *SORT ?
For ispf FILE-TAILORING i went through the example you provied, but could not get much.

Thanks.

If job submission is what you want to achieve, why not submit it asa the template is updated for each member name? If the template is a simple JCL as the example below, then simply update the member name and route the output to INTRDR (JCL lines for this are commented in the example).

Yes, it can be done using SORT (DF*/SYNC*) with OUTFIL sub-functions and SYMNAMES.
If you're not very comfortable on either (learn them, they are really useful), use REXX, it'd be much simpler as the code is more easily discernable and end-logic is completely user driven as against *SORT.

Hope you referred the links shared by 'Superk' and 'Expat' as well. Think of it as learning a new programming language, some work will be required here- should you want to go that way; but the results are worth the time spent.

Hey thank you so much for this jcl. This is working perfectly for me.
But the issue what i have is, my input file is a PS file with list of memebers.
Here's an example:-
MY.WORK.PS.FILE---This has list of memebers
ABC1
ABC2
ABC3
ABC4
ABC5
So, how can i get 5 output jobs for 5 members?

Thanks.

By browsing the forum where there are several examples of what you are doing.
The problem I have is that people can explain things quickly but I can only comprehend slowly.

Hello,

As Mr. Clouston has stated, the bare minimum expectation here was that YOU'd read the manuals, search the forums and build forward accordingly as the keywords and a working sample was provided for a DFSORT solution; share what you'd developed and in case of errors we could've guided you - instead of you looking for a final-working solution.

Here's a quick and dirty solution though, I'd leave it unto you to figure out what each command is doing by referring the manuals; note, you'll still be required to build your own JCL and symbolics:


//SORTJCL JOB 'SAMPLE','SYMNAMES',                                      
//        CLASS=A,MSGCLASS=X,                                          
//        MSGLEVEL=(1,1),                                              
//        NOTIFY=ME,REGION=0M                                          
//*                                                                    
// SET SEG='0',                                                        
//     LIBRARY1='(TEST.LIB1,',                                          
//     LIBRARY2='TEST.LIB2)',                                          
//     MEMLIB='MYPDSMEM'
