IBM stopped to support it. Even on 2064 with CCF it required
COMPAT(YES), while suggested option is COMPAT(NO). This parameter
provides compatibility with quite ancient tihings like PCF (pre-ICSF,
pre-OS/390).
I disagree. The ENCIPHER option of REPRO is written to an old interface
(PCF) but it is still clearly documented and supported, even in z/OS
1.7. It only supports single DES encryption, but it does work.
I didn't mean IDCAMS REPRO itself (however I was unclear). IBM dropped
support for REPRO in new hardware crypto features. In other words it is
formally supported, but doesn't work on machines z/990 and z9. Last
machine that supported REPRO encipher is z/800 (z/900 for bigger
customers) - it's becoming history.
In the ICSF manuals, the COMPAT option gives you the ability to run both
ICSF and PCF together, or to run ICSF with PCF-compatibility.
IMHO doing something new in basis of PCF is unwise. PCF is really
obsolete. It was (is, as you wish) available as downward compatibility
option of ICSF, but COMPAT(YES) has several drawbacks from operational
point of view.
So, I'd repeat my advice: get rid of PCF-like solutions.
