If you are asking to dynamically define a data set name in step 1 and refer to it in step 2 of the same job - this cannot be done. You can submit another job to reference the data set.

How about output second step to a fixed name and rename or copy it, generating the control cards to do so.

Yes 2nd step is fixed..

Illustration : highlighted in bold and italic

//Step1 pgm..
//input dd dsn=inputfile,disp=shr
//output dd dsn=123.out,disp=shr ==> 123.out contains "abc.xyz"
//************************************************************************************
//step 2 pgm..
//input dd =abc.xyz,disp=shr
//output dd=outputfile,disp=shr

Use dynamic allocation in the step 2 pgm. Both COBOL and PL/I can do it.

For a similar process, I read the file name from abc.xyz in step2- cobol program and use BPXWDYN to allocate and read the file.

Thanks,
Ashwin.

If I understand you correctly, this is a very simple thing to do. I believe that you want to use symbolics. For example...

Select all

//SET FILENAME='THIS.IS.YOUR.ABC.XYZ.FILE'
//S001 EXEC PGM=XXXXX
//INPUT DD DSN=INPUTFILE,DISP=SHR
//OUTPUT DD DSN=&FILENAME,DISP=SHR
// DISP=(,CATLG,DELETE),
// STORCLAS=SCPROD,
// SPACE=(CYL,(177,2777),RLSE),
// DCB=DSORG=PS
//*********************************************
//S002 EXEC PGM=YYYYY
//INPUT DD DSN=&FILENAME,
// DISP=SHR
//OUTPUT DD DSN=OUTPUT.FILE,
// DISP=(,CATLG,DELETE),
// STORCLAS=SCPROD,
// SPACE=(CYL,(177,2777),RLSE),
// DCB=DSORG=PS
