ZXList - a P-to-BASIC lister for Sinclair ZX81 program files

Source code here is C++ tailored for the command line. Includes a Visual Studio 2022 project for Windows Console (command line application)

It will generate ASCII text and send it to the console. If it looks good, you may redirect it to a file, e.g. ZXlist7 file.p > file.bas

Also includes a programmer's option to generate BASIC lines suitable for assemblers such as ZX-IDE and Sjasm / sjasmplus, the commonly used cross-platform assemblers for the ZX81

Usage

ZXList7 v1.0 a P-to-BASIC lister for Sinclair ZX81 program files

Usage: ZXList7 file.p

For BASIC db assembly Usage: ZXList7 file.p --a

For a full assembly file Usage: ZXList7 file.p [--a:zxide | --a:sjasm]

Routines

There are two main routines:

• P2ascii - generates a BASIC listing in ASCII text
• P2asmDB - generates a partial assembly file in DB (Defined Byte) format. This is generated from the BASIC part of the P file

Optionally can include the full assembly file by specifying sjasm or zxide. The resulting file will assemble into a working P file

Contributions

Contributions welcome

To do items (not yet implemented):

• add support for P files in Lambda 8300/Power 3000/Marathon 32K/Your Computer format. This is a once-popular clone of the ZX81 with sound & slightly improved graphics. The file format is arranged differently and some keyword characters are altered
