driver JCL



Procs Look like this



I want My Test JCL/Driver JCL in below way



In brief, I am looking a way out to read the PROC's symbolic parm statements (e.x. PFX1, PFX2 etc.) and want those to add in the test/driver JCL itself. Please help to get it done in easy way !!

see here how to parse an exec statement

Hi Enrico,

Thanks for sharing the links. But the contends are very complex to as I am just a beginner in REXX. After searching the solution for my requirement, it seems that a EDIT Macro ( using REXX) may serve the purpose. But unfortunately I don't have proper knowledge to Code the macro. Please give a heads up, so that I can extract the Symbolic parms from procs and add/include those in driver jcl. Please

if You are a beginner in REXX most probably the task is above Your skill level

the ISPF edit environment is relevant only in the INPUT/OUTPUT stages,

Please give a heads up, so that I can extract the Symbolic parms from procs and add/include those in driver jcl

the snippet I posted just does that ...
extract from a jcl stream everything in the format SOME_KEYWORD=SOME_VALUE

the snippet was tested on my pc, but apart the STREAM/LINEOUT functions used for I/O
everything works also under TSO/REXX
and if YOU/YOUR SUPPORT install the rexx STREAM I/O function package everything will work ASIS

Hello,

Please give a heads up, so that I can extract the Symbolic parms from procs and add/include those in driver jcl. Please

While you can ask what you believe is s simple queston, the answer might not be so simple. . . .

Not everything can be done quickly - especially by one with little/no experience.

Hopefully, there is someone in hyour organization who is familiar/fluent with REXX who can be a mentor/trainer.

• so that I can extract the Symbolic parms from procs and
• add/include those in driver jcl.

You will need two different rexx programs, for the items above. I suggest they communicate through the shared pool.

Hi Pedro,

You mean
1. First REXX will read the Drivev JCL lib for a selected/supplied job and will build the jobcard with necessary JOBLIB's, JCLLIB/PROCLIB's and EXEC statements to identify the PROC name. and then it will call the second REXX
2. Second REXX will read the the PROCLIB based on the proc name as found in first REXX, then extract the SYMBOLIC PARM statements and include those in the JCL created by the first REXX.

To do the job for point #1, I have a CLIST program that calls a REXX program, but unfortunately this REXX program reads the proc lib and expands it. I have the REXX code for this but, unfortunately as I am new, I am not able identify how to modify this existing REXX program so that it only perform my requirement. I am digging in. Lets see if I can get a breakthrough ...
