Learning ZX BASIC

Language Reference

  • Language syntax
    Language Syntax is very close to the original Sinclair BASIC, but it's expanded and enhanced.

  • Data types
    Language data types: Instead of working always with Floating Point numbers (also available), there are also some integer types which are faster an take less memory.

  • Reserved words
    Comprehensive list (alphabetically ordered) of identifiers you shouldn't use as a ''variable name''. E.g. FOR, PRINT. If you want usage instructions on a statement, also look here.

Compiler internals

Only for true hackers: This explains how the compiler does it job, how to expand it, etc. You must be a bit crazy if you enter here...

Other Architectures

ZX Basic was designed from the base as a Retargeable Compiler, so it should be not hard to extend it to other architectures. This is work in progress. See other architectures for more info.
