Maybe in the later days but Turbo Pascal originally was written in, AFAIK, 100 percent assembly code, with not a single source comment... Anders was very secretive about his code as he didn't want people to steal it and protected it closely In the later (or latter) days, Borland decided that assembly code was not so easy to maintain... I thought they made this decision in delphi days, but maybe they made in at some point in Turbo Pascal days and converted some of Anders assembly to turbo pascal. ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

This site is around for years, so if something would be way out of whack on how he got the source code, I am pretty sure Borland/Inprise/Codegear/Embarcadero would have gotten on his case a long time ago.

Re: [fpc-other] How was compiled the very first version of FPC?
And ultimately I think that TP was written in Z80 assembler, later converted to 8086. Actually, I don't know about versions pre 4.0), but source code versions of tp 6 have escaped into the wild, and if you can locate one of those, you'll see turbo pascal is written in turbo pascal as well. There's assembly language for some routines to speed up certain parts of the code, but in general, it's mostly pascal code. Interesting, but I never did look at the code itself, since I didn't have the tools required to compile it, so it never interested me. Of course, I haven't a clue where you'd find such a thing these days, last time I saw it was about 10 years ago, on some chineese site, so who knows. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other

As compiling FPC from sources requires a previous FPC version, how was compiled the very first version of FPC? The point 4. is correct. The first version was done in Turbo Pascal, then eventually the compiler became able to compile itself. Until 1.0(?) I think it was still possible to build the compiler with TP7. Later the TP7 compatibility was dropped, and since then FPC is only developed in itself. It's written on Wikipedia BTW: https://en.wikipedia.org/wiki/Free_Pascal#Early_years And ultimately I think that TP was written in Z80 assembler, later converted to 8086. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-other maillist - fpc-other@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-other
