Well, the vanilla DOS version would run on Win NT (it is just an MS-DOS program without much extra). But it's limited in the size of programs it compiles (the symboltable has to fit in 640K, and Text_IO takes up more than half of the available space). The DOS Extender hosted version of Janus/Ada 83 (which is not limited in the size of programs) doesn't work on Windows NT, although it does work on Windows 95/98/ME. The DOS Extender company went out of business instead of fixing it when we complained. :-( It would be possible to compile a Windows NT hosted version of the Janus/Ada 83 compiler, but it would take a bit of work (because of Ada 83-95 incompatibilies and system-dependent code). So we'd have to charge a bit extra for that. Write me a note at randy@rrsoftware.com if you're interested. Randy Brukardt. >Thank you, Debs.
