Bernd:
My personal opinion is that LE did the job of killing off compilers
(PL1 COBOL etc).
LE tied the level of the OS to the compiler.

I agree with most of that, but: on a site which uses such an old PL/

version there is not much life on this platform. The platform seems
already to
be almost dead there (if not PL/1 is only, say, 5 % of the
inventory, and
the rest is, for example, COBOL ... then staying with such old
releases could
well be a matter of economics ... I would not act this way, if I
had to decide,
but often such decisions are not made by tech people. BTW, at the
site where I am
working, we are staying with EP PL/1 3.9 for similar reasons since
three or more
years now, I think).
Kind regards

The reflexive identification of what is "real-world" with slothful,
reactionary, risk-averse, "if it ain't broke, don't fix it" practices
is killing this platform. In this particular case it is almost
certainly uneconomic too. Compiled and optimized PL/I code is
different for different ARCH levels. That for, say, ARCH(10) is
very
much better adapted to z/Architecture than the default.
