since you have posted this in the COBOL forum,
and you have used the terminology file description,
i am forced to assumed that you are reading a ps file with a cobol program
and are populating a vsam ksds file.
if the record descriptions were the same, you could have accomplished this task with IDCAMs REPRO.
but, if as your remarks imply, there is an additional field in the ksds record,
you would need to populate the ksds record one field at a time (via MOVE instructions) from the ps file,
and then provide a value for the 'new/additional' ksds record field.
since the records are not the same (additional field in ksds),
the file description can not be the same.
suggest you download and read IBM Redbook - VSAM Demystified.
also, suggest you revisit (if you ever have) the COBOL Programmers Guide for your version of COBOL.
