If I allocate a DATASET in JCL, either manually, or with IDCAMS, such as:

//VSAMCR JOB 
//DEFINE EXEC PGM=IDCAMS 
//SYSPRINT DD SYSOUT=*
//SYSOUT   DD SYSOUT=*
//SYSTERM  DD SYSOUT=*
//SYSIN DD * 
DEFINE CLUSTER (NAME(PJVSAM00.00000000) -
               CYLINDERS(1) VOLUMES(LZ0000) -
               INDEXED KEYS(10 179) -
               RECORDSIZE(240 240) -
               ) -
         DATA (NAME(PJVSAM00.00000000.DATA)) -
         INDEX (NAME(PJVSAM00.00000000.INDEX))
/*

How can I populate that file with some initial content, such as that from an INLINE DD, like SYSIN above, so that I can use that file in a subsequent JCL step?

You need to create it in a step running some program (e.g., *Sort) that writes to it.

You can use the IDCAMS REPRO command to copy data into the new dataset.

As has been said, REPRO has been favorite when it comes to VSAM:

Code: Select all

//COPYDATA ,'job-name',CLASS=class,TIME=(mm,ss)
// EXEC PGM=IDCAMS
//SYSPRINT DD SYSOUT=class-name
//indd  DD DSN= ... (the input data set)
//outdd DD DSN= ... (the output data set)
//SYSIN DD *
REPRO -
  INFILE(indd) -
  OUTFILE(outdd)
