OK this is interesting lead! So what you are saying is that some oldish version of DLANG compiler can actually run on MSDOS as it does have Zortech C++ compiler from 1993 as backend? This is still "cheating" - but VERY promising! Thank you sir. Any chance for link to actual MSDOS compiler in such old version?
