Thread: Which Vintage Computer Used These BASIC Commands

  1. #1

    Default Which Vintage Computer Used These BASIC Commands

    I am trying to figure out the language to Kim Watt's Support-80 BBS, and I know it isn't TRS-80. If anyone knows what computer basic might have include all the following, please let me know:


    PRINTCHR$(12);CHR$(2; - Probably to clear the screen
    CHANGE Y TO N$ - Probably changes an integer to a string and vice versa
    IF END#1 THEN 370 - Probably an EOF type checker
    IF SBS$(M$,L,L) = "]" THEN 1200 - Probably MID$ or any SUBSTRING setting
    M=SEA(Z$(L),"=") - Probably an INSTR or substring search returning the position of the searched character

    Thanks!

    ZBasic maybe?

    Where'd you get the source code?

    I checked the ZBASIC manual and at least for a TRS-80 those are not valid commands. The source would have been on a TRS-80 formatted disk I got from any of myriad people. Since the files are saved in ASCII, I can't just assume they are TRS-80 because they were on a TRS-80 disk. However, these are not commands from any TRS-80 BASIC I know.

    The limitation to 3 characters for function names tells me that this was probably a very early/small BASIC. That's all I've got.

    IF SBS$(M$,L,L) = "]" THEN 1200 - Probably MID$ or any SUBSTRING setting

    The Microworld Basic for the Microbee uses very similar eg. A0$(;2,4) to simulate MID$

    From its manual

    MICROWORLD LEVEL II BASIC is based on a BASIC interpreter
    written by East Texas Computers. It was developed by John Arnold
    and Dick Whipple who, incidentally, were the originators of the
    first TINY BASIC.

    The only function I could find was IF END#1 which is in CBASIC and many BASIC closely derived from the Dartmouth standard.

    Are these spellings from source code or OCRed printouts? I could see OCR changing SEG into SBS.
