Hi, just to discuss a bit off-topic (well, non-Python) programming ....

What exactly are you looking for? Garbage collection? OOP? Dynamically typed language? What Ralf is referring is (I think) "batteries included". Is the ecosystem (modules) what you really need? Would Perl (we only have old 5.8.8) + CPAN work? Or is just any scripting language convenient for you? I'd (almost) recommend AWK since it's a POSIX standard tool (and DJGPP's port of GAWK is still updated and has an excellent included manual). Then again, REXX is an awesome scripting language, and Regina (free/libre implementation) is quite nice. Granted, our version is "slightly" old (same old story), but it works fairly well. I just never bothered fiddling "too" much with it as I'm not fluent in it. (But Howard Fosdick did release his full book as freeware nowadays, so that might help you a lot. REXX is also standardized, aka v5, ANSI 1996. But Regina omits the newer, popular, non-standard Smalltalk-esque OOP of ooRexx. I'll bet somebody could rebuild that with DJGPP G++ and FSU Pthreads, but who knows, never tried.) There are also some ways to run Oberon in DOS, and it's quite a nice language, too. Not quite scripting, but it has OOP and (usually) garbage collection. It's basically an improved (but simplified) Modula-2, which was an improved Pascal derivative (which was an improved Algol 60 derivative). Though, just to be honest, the Turbo Pascal (and Free Pascal) ecosystem is more robust and popular overall, even if that lacks garbage collection (but has other virtues). Modula-2 isn't quite dead, but it's similarly somewhat obscured like Oberon. (I wish I knew if GM2 will ever build with DJGPP. I am not quite insane enough to try! There are other M2 compilers, but ....) Ada is even worse supported (for DOS), but you can kinda make GNAT work, mostly. So it just depends on what you want to do. You can't be stuck to a single language these days, there are too many tradeoffs and omissions for any one language to do everything (and the kitchen sink). Portability can be very important. Other cool languages (well-supported on DOS): FreeBASIC, C++, Lua N.B. I don't know if you really care about standardization, and certainly I'm no expert, but Pascal had two, Modula-2 had one, Ada had several, and of course C and C++ both had several. But the BASIC standards are quite unpopular and ignored (more than Pascal, even). Most people use "de facto" standards (e.g. Turbo Pascal or Delphi, MS QuickBASIC, etc). _______________________________________________ Freedos-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/freedos-devel
