HiSoft C

Versions: 1.0 (1984) to 2.03.02 (1990)
Company: HiSoft / Loriciels
Developers: Pierre Morel-Fourrier

An interpreter for most of K&R C. It could load and run compiled objects while interpreting C source files. Version 1 was painfully awkward to use, but v2 has a nice editor and is well integrated with the GEM desktop.

I tried several Atari emulators, but only Hatari was stable with HiSoft C.
