Edward,
This topic started because Johnny Luo asked about the contents of
an object
module. My reply included a reference to the REP card and thus another
strand of the original thread spun off. (This covers Ray's question.)
In the thread I reminisced over a particularly tricky use of the
REP card to
compensate for a PL/1 bug in CICS. I believe it was an, I expect,
unintentional 32K limit to a CICS PL/1 transaction program. I'm
pretty sure
this was a VS1 system since I'd outgrown DOS (VSE) by then and
hadn't yet
made the complete step to MVS. It was 1973[1].
Since this indicates the use of the REP card was permitted in at
least one
of the "big brother" systems, I'd be inclined to expect it to be
available
to all. However, I checked the z/OS "Program Management" manuals
and none
confess to knowing anything about the word "REP".
[1] The reason I recall the details is that I was getting a suite of
demonstration programs ready to show that Cyrillic 3270s actually
worked.
The Soviet ministry's machines lacked PF keys which were a key
feature of
the demonstration suite. Each program needed to be modified and one
broke
the 32K mark. Fixing up the programs was more high pressure than it
might
have been because I was having to do the work in Vienna[2] away
from my
usual technical base. In Vienna the changed programs worked. Did
they work
in Moscow? No. Fortunately very shortly afterwards, it was
discovered that
Cyrillic 3270s needed X'BF' as the poll character rather than X'7F'
and the
suite worked as it should - so I was told.
[2] Something else I remember, as was a granite habit, I took two
copies of
the programs on tape. In this case, the first one didn't work.
Maybe it was
a reflection of the tape technology of the time.

Chris,
I too remember rep cards but honestly don't remember where that they
were documented. That is why I asked the question. I *vaguely*
remember them from 25+ years ago. I was just hoping that someone
would know if they are still supported and if so where they were
documented. I would have suspected (if they still are supported) that
they would be documented in the binder manual (program management).
They (as you say) don't seem to.
Just a point of curiosity thats all.
Ed
