zxtools

Two (count 'em) tools to help with cross-development of ZX81 programs.

Built on the shoulders of the giants that are:

• Chris Cowley
• Russell Marks
• Jack Raats

Thanks fellas.

Binaries are available pre-compiled for windows and mac/linux.

zxtool will:

• decompile a P file into its associated BASIC text
• dump variables and their content
• dump the SYSVARS
• remove a P file's auto-run
• force a P file to auto-run at a particular line number
• extract and insert arbitrary lines of code

ZX81 P-file Utility by SirMorris  V1.5

Largely based on ZX81LIST (C) Jack Raats, Steenbergen 1992

  Usage:
    ZXTool [p-file name] ([option]...[option])

  Options:
    vrb            : verbose. Extra information is printed.
    list           : produce program listing.
    vars           : produce variable listing.
    sysvars        : produce system variable listing.
    noauto         : stop the program from auto-running.
    auto=[line]    : make the program auto-run from the specified line number.
    extract=[line] : extract program line to temp.q
    insert         : insert/overwrite program line from temp.q
    zxpand         : use extended ZXpand+ BASIC tokens

  If no options are specified, a listing is performed.

mbp:zxtools charlie$ 

zxtext2p will:

• compile a text-based representation of a zeddy program into a standard P file
• allow development without line numbers, using a label-based system for GO(TO/SUB)

mbp:zxtools charlie$ ./zxtext2p -h

usage: zxtext2p [-h] [-i incr] [-l] [-o output-file] [-s line] [input-file]

        -h      show this help information.
        -i      in labels mode, set line number increment. (default = 2).
        -l      use labels rather than line numbers.
        -o      specify output file (default `out.p').
        -s      in labels mode, set starting line number (default = 10).
