[net.wanted] C on IBM main frames

je@hhb.UUCP (Jon Eiseman) (09/25/84)

	Has anyone had any experience with C compilers on IBM main
frames? In particular Whitesmiths or Amdahl's UTS. Any information
would be appreciated.

Amdahl at last check does not sell the C compiler for use under the
conventional IBM OS's.  It only runs under UTS.  I tried to convince
the Amdahl salesman that a VM/CMS version would be rather popular and
he said he would relay my enthusiasm to their management.

RDS C is a piece of junk and does not work well enough to use.  I've
posted news on this before.

My IBM friends just got the Bell compiler which is supposed to be very
good but does not run under VM.  It runs under MVS.  There are some
helpful hints distributed with it on how to convert it to VM.  They
haven't worked on it yet.

Waterloo has a C compiler that works on VM/CMS and will be available
shortly for the IBM PC, MVS, and other computers.  It is written in WSL,
a machine independent systems development language and is nearly compatible
with Unix C.  The differences are in the types of some of the I/O library
routines, but this is always a difficult area in portable C programs.
I have ported Unix C programs to VM/CMS using Waterloo C and they have compiled,
but the I/O routines needed changing.  Also the math library works in
double precision always.
