But from the Unix system, I need to be able to generate the
above very simple compile script, which is a precursor to creating
very simple JCL steps (trust me, you don't want to see what
ST2CMP looks like). Note that the JCL has the filenames
truncated to 8 characters, listed twice, uppercased, and '-'
and '_' converted to '@'.
Why are you not making use of z/OS Unis System Services? GNU Make and
other GNU tools are available and already built for z/OS.
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.
Perhaps because he is a hacker in the good ol' sense of the word ?
Mjam, MVS, JCL, the possibility of COBOL, perhaps even PL/1 ...
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.
[ Over a quarter of century ago I worked at the computer center
of the Dutch Postal Service. One of my colleagues managed the
IBM system group. He had an assistant to write the JCL jobs he needed
for him. ]
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. :-)
