[Coco] C interpreter for Coco BASIC?

[Kip Koon]

Hi Lee,
I am definitely interested in a copy of this Small Basic in C.  The C source code has to be much better organized than Color Basic's original assembly code.  Argh!  I never could make total sense of it all!

Years back I found something called Small Basic. I just googled it again, and got some other hits that didn’t seem like the same thing. Wish I had kept track of where I originally got it from. I was able to update it to use labels instead of line numbers, and actually used it as a script interpreter for MUD I worked on. Pretty simple interpreter to use and modify. 

Very small, consisting of 2 files and a total of 877 lines:

     334 EXPARSE.C
     543 SBASIC.C
     877 total


Supported the following:

        "print",  PRINT,
        "input",  INPUT,
        "if",     IF,
        "then",   THEN,
        "else",   ELSE,
        "goto",   GOTO,
        "for",    FOR,
        "next",   NEXT,
        "to",     TO,
        "gosub",  GOSUB,
        "return", RETURN,
        "end",    END,

    Before I go roll my own interpreter for the Coco tokenized BASIC, anyone 
    know of an open source C implementation?
