How do you get dataset create date from batch COBOL?

Want create date from the catalog for the input file, write it onto the output trailer. Mix of DASD and tape.

Calling ISPF/REXX from batch COBOL feels heavy. IDCAMS LISTCAT from COBOL? Separate IKJEFT01 step?

Cheapest: IKJEFT01 / LISTDSI or a CLIST before the COBOL step, pass the date in a parm file.

IDCAMS LISTCAT callable from COBOL works too if you already have that pattern in the shop. I would not drag ISPF services into batch for one date.

Went with a LISTDSI step writing a 1-line date file. COBOL reads it. Fine for now.
