Pass value from Rexx to JCL

I have a requirement to pass information from REXX to JCL.

To make the requirement more clear

I have a file HLQ.FIRST and I need to create a new file HLQ.SECOND with all the units same except record length.
I want the lrec of second file to be Lrec of 1st file + some variable (20 or 50 for example).

So I am getting the record length of the 1st file from REXX and want to add it to lrec of second file
I want the creation of 2nd file only by JCL and not through REXX.

Hope the requirement is clear.
Could someone please help me out?

OK. I'm not clear to what your problem or question is. Your process seems to be rather straight-forward.

Passing data from a step back to the job stream has been discussed many times, the only thing you can pass back to the job stream from a step is a return code.

Maybe I'm reading more into this topic than was intended. I'm thinking that the O/P is going to create and submit the JCL from this REXX exec to create and catalog the dataset as per the requirements. Or, in my opinion a better process, to create SORT SYSIN records for a subsequent step that copies the exisiting dataset to a new dataset with the record length modified.

But you could invoke ISPF to use a skeleton to create and submit a batch job

superk,

I will make my problem more clear.

I want to create a flat file using a jcl.
when i submit the jcl for the first time the lrec of newly created file should be 80 say( i have hardcoded 80 in my jcl). i am using this flat file in my rexx program.
That will be fine.
the program is over.

When i used the same rexx exec next time then
i want to create the flat file again now lrec should be 80+x
where x is a value that differs each time and it will be present in the rexx exec.

i want to pass that x value in rexx ecex to jcl.
is that possible???

Hi kavya123 !

But you could store the LRECL in a variable in profile pool. So at the next use, you could read and modify the Lrecl. Then you could use FileTailoringServices for Skeleton-JCL.
