Programming In BASIC Language

Below are four links to the wiki pages for developpers in BASIC language. All MSXs have a BASIC editor that starts by default. In this language each line is numbered at the top in ascending order. Each line can contain several instructions separated by a colon (:). If you enter an unnumbered line, it will be executed directly.

SAVE instruction allows you to save your program and LOAD or RUN allows you to load and execute it. Your program saved on disk can be executed automatically after the MSX initialisation if the file is named "AUTOEXEC.BAS" provided that MSX-DOS is not installed because the DOS boot is priority.

• MSX-BASIC Instructions (in alphabetical order)
• MSX-BASIC Instructions (per category)
• MSX-BASIC Extensions
• MSX-BASIC Error Messages

Some other BASIC languages are very close to MSX-BASIC, at least the version used for MSX1 computers, and you can therefore easily adapt the programs:

• SVI-BASIC
