Does anyone know what programming language was used to write ProIV in. I'm not looking for a history lesson about Sushil...just what he used to create this beast we call ProIV.
TIA.

Hi,
Actually all the early versions were written
in native assembly for whichever machine
Pro-IV was being ported to. Sushil was
real keen on keeping the kernel extremely
small and fast. The 'C' version was written
around 1984 or 1985. At that time I was
supporting the CIE Systems 68000 assembly
language version.
PCS and CIE Systems eventually went separate
ways leaving at least 2 incompatible versions
of Pro-IV. I think the CIE Systems version
(20 years without change) is still being used at
one or two sites in California, but maybe they've upgraded
to something else finally.

The 1.2 version I used on a MicroVAX in 1984 in the UK was assembler.....
I cannot recall where I got the idea about Fortran from. Maybe Sushil's first versions of Pro-IV were in Fortran.

When we dealt with PCS we had versions on the AT&T systems, the PC, and Xenix boxes installed at my customers sites back in the early 80's.
They were all written in assembler.
