PFR was not supported in OS/360 (MFT nor MVT) IOCS at least through Rel. 21
and
yes it was supported in DOS which was the "logical" upgrade path for
1400 series customers.

You had to write your own channel progams ensuring the correct ordering of
type A and B CCW's.

I wrote a civilian payroll system for the 1401 that I migrated to OS/360 MFT
Rel. 19 around 1968/69 while I
was a member of the U.S. Marine Corps.

Semper Fidelis!!!

PFR was certainly possible under OS/360 - it was key to the original
Barclaycard systems used by Barclays Bank at Gladstone Road Computer
Centre in Northampton, 1969-ish.  The original Barclaycard statement
was an 80 col/51 col turnaround document, both printed and punched
with the account information.

I have to admit to being one of the three Assembler programmers on the
team that maintained the code and not being able to remember how we
did it.  I think it was EXCP.  The bulk of the programme was actually
highly modular COBOL E and I remember the phenomenal difference
PARM=NOSPIE made to its execution.
