• Re: fast compiling, Whither the Mill?

    According to Thomas Koenig <[email protected]>:
    Modern PC's are orders of magnitude faster, but still don't have
    "instant" compile times by any means.

    Could be faster though, but would likely need languages other than C or
    (especially) C++.

    I assume you never worked with Turbo Pascal.

    That was amazing. It compiled code so fast that it was never a
    bother, to wait for it, even on a 8088 IBM PC running at 4.7 MHz.

    Back around 1970 the Dartmouth Time-Sharing System (DTSS) ran on a GE
    635, which was about the same performance as the original PDP-10 and a
    front end DAtanet 30 which had about the compute power of a modern
    toaster. By clever system design they made it support 100 users, and
    the response time was really good. The time from when you typed RUN to
    when your program was compiled and started running was too fast to
    notice.

    It was a real time-sharing system that supported multiple languages,
    not just BASIC, and the languages were all compiled, not interpreted.
    The compilers were so fast that for years they never bothered to write
    a linker, since you could just compile all the source code for your
    routines togther. (They finally wrote a linker they added PL/I.)
