USS is not available for free, or even for a price on MVS 3.8j,
and it is not native MVS, it is an expensive overhead.
It's a bit like asking "why don't you use a JCL emulator instead
of make on Unix?". :-)
You know, even as a batch job with JCL, people then said to me
that reading the C source from a file instead of "standard input"
(ie stdin, ie //SYSIN DD) is really weird, and so I had to make a
pretty small mod to GCC to allow "-" as the filename, so that
the JCL at least looks like a normal MVS compiler.

Both Cobol and PL/1 front-ends are already supported to some
extent ...
http://www.opencobol.org/
http://pl1gcc.sourceforge.net/
although we're not really at the stage of even attempting to get
that onto native MVS.
Actually, PL/1 basically requires GCC 4.x, which is my main
interest in upgrading 3.4.6 to 4.x. :-)
Someone else said he would like to see PL/S, and maybe if
PL/1 was available, the super-secret PL/S language would
start to be made available.
But it all rests on getting the HLASM-generator working on a more
modern GCC. :-)
And C90 is the lingua franca.

Maybe for old times sake you'd like to load up:
http://mvs380.sourceforge.net
It comes with GCC so you can now do what you always wanted
to do back then. :-) And of course, all perfectly usable on z/OS
too. Natively. :-)
850,000 lines of assembler. Like wow, man. I wonder what
GCC 4.4 will clock in as? 3.2.3 was 700,000, so we're probably
up to a million lines of pure 370 assembler. :-)
BFN. Paul.
