DOS v1 was more like CP/M, but DOS v2 added file handles and redirection. C compilers for DOS were abundant. C came from UNIX. > Some *ix utilities MIGHT be useful for the use on DOS, MKS Toolkit?

So their overall philosophy (esp. "open source") still applies greatly to FreeDOS (or others). * http://www.catb.org/~esr/writings/taoup/html/pr01s01.html [partial intended audience, but others welcome too] "You should read this book if you are a non-Unix programmer who has figured out that the Unix tradition might have something to teach you. We believe you're right, and that the Unix philosophy can be exported to other operating systems. So we will pay more attention to non-Unix environments (especially Microsoft operating systems) than is usual in a Unix book; and when tools and case studies are portable, we say so."

I have used most of these on FreeDOS host for FreeDOS target. That is the advantage of "portable" or "standard". I'm not tied to "UNIX" exclusively. > And yes, an article, possibly a series of articles, about programming on > DOS, for DOS, will be forthcoming... Would you prefer an article on Pascal? I know you (also) are a fan of it. An article from your experience there might be useful. I built and tested P5 Pascal (ISO 7185) with GPC (and GNU Make) for DOS, Windows, and Linux. I built and tested P4 Pascal subset (via p2c) with GCC and OpenWatcom for DOS, OS/2, Windows, and Linux. p5c works with modern GCC (e.g. DJGPP) or Clang. DJGPP still includes old GPC (ISO 7185, ISO 10206, BP 7). FPC still supports Go32v2 host / target and i8086-msdos target (with {$mode tp} or {$mode iso}, et al). (For UNIX Pascals besides FPC, Berkeley, ACK, and GPC are all on Github.) _______________________________________________ Freedos-user mailing list Freedos-user@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freedos-user
