I've been doing some programming in Microsoft Fortran for CP/M. It's been fun trying to remember how it all works. Microsoft Fortran seems to work quite well - it's a Fortran IV system with a little left out (complex numbers) and a few things added. In general, it works as expected.
For anyone wishing to play around, I've uploaded a zip file containing the necessary files, and a scan of the entire documentation set in pdf format. You can find it on the Documents tab of this Group.
The binaries can be read directly into a SIMH disk with the "R" command.
This package retailed for $500 back in the day. Quite a sum for 40 years ago!
Have fun!
Tom
