AFAIK, DFSORT does a best match based on whatever options, available REGION,
workspace and SORTIN it receives.

Good question...

What you can do is, if you can know in a way BEFORE, how big your sort input
is, you create a parameter file, insert your DYNALLOC statements and pass it
along when you call DFSORT from your COBOL program:
From your sample in this thread:
SORT FIELDS=(0005,0605,CH,A)
RECORD TYPE=V,LENGTH=(009332,,,000629,00003000)
OPTION MSGDDN=SYSPRINT,DYNALLOC=(SYSDA,<insert your own
estimate>),EQUALS,FILSZ=E79326420
There is an IVP Assembler program available which demonstrate this scenario of
creating a parameter file which is passed upon calling DFSORT.
HTH!
