Hallo,
Good Morning, I have a requirement to fetch a value from the first record in the input file and use that value as a symbolic variable to generate the dataset names in the subsequent steps.

I understand that I can achieve this as follows:
1) 1st step of the JOBA - Get the value from the file and build the SET statement and write it to a PDS member - PDS.LIBRARY(NAMEDS).

For instance // SET NAME=LENOVO

2) 2nd step of the JOBA - Use program like EZACFSM1 and provide a new job JOBB in the instream data and mention the JCLLIB and Include the member (NAMEDS) generated in 1st step and use the symbolic variable in the DSname of the new job and write the output of this JOBA step to internal reader

No - once the job has been submitted then the JCL is finalised. The only 'changes' possible are dynamic data set allocation.

Thanks Nic Clouston for your thoughts...Can you please share a sample JCL of how to achieve this in a single job instead of creating 2 jobs...Thanks...

Hi Kolusu,
Thanks for the response and Sorry, if the question/reply was bit cryptic...

The reason I prefer single job is that I need to build a generic job to be used to work with different kinds of data and also if feasible schedule that
job in the scheduler with predecessor/successor jobs.

For instance if the input file contains key word 'Lenovo' I need to process the data for 'Lenovo' and run 4 to 5 steps for this input file and generate
different GDG's (Some of these are tape datasets as they are used to store huge volume of data)

Here are preview of various job steps -
Input File - XXXXX.COMPANY.DATA

Step1: Take backup of input file
Input File: XXXXX.COMPANY.DATA
Output file: XXXXX.COMPANY.DATA.LENOVO.BKUP(+1)

Step2:
Input File: XXXXX.COMPANY.DATA.LENOVO.BKUP(+1)
Output files:
XXXXX.COMPANY.DATA.LENOVO.GOOD.RECS(+1)
XXXXX.COMPANY.DATA.LENOVO.BAD.RECS(+1)
XXXXX.COMPANY.DATA.LENOVO.SUSPENSE.RECS(+1)

Step3:
Input File:XXXXX.COMPANY.DATA.LENOVO.BAD.RECS(+1)
Output File: XXXXX.COMPANY.DATA.LENOVO.ERROR.REPORT(+1)

Job goes on for several steps working with the data processed by previous steps...


So this way input file contains data for various companies like Dell, HP and so on and everytime I need to process the data for specific companies and generate
company specific GDG's...

Please correct me if I am wrong, your suggestion would work if it's a sequential DASD dataset but not sure if it's feasible for GDG Tape datasets...Appreciate your response...

Thanks a lot Kolusu for your suggestions...it sounds like we cannot create the PDS member with symbolic variable declaration/definition in the same job and use it. So the only way is to create PDS member in predecessor jobs...Thanks again...
