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. -- Phil Payne The Devil's IT Dictionary - last updated 2002/01/20: http://www.isham-research.com/dd.html UK +44 7785 302803 Germany +49 173 6242039
