Description

Below is a list of all standard MSX-BASIC instructions, that are not linked to a localisation (Arabic, Japanese, Korean), the presence or addition of a device such as a disk drive or a RS-232C interface, or the usage of a program that adds specific new instructions.

Generally, all instructions corresponding to a MSX generation will also work on the higher generations, but there are some exceptions, for example the instructions related to the data recorder will not work on a MSX turbo R.

Although the instructions added by MSX-BASIC 4.0 (MSX turbo R) begin with CALL, they are included in the standard MSX-BASIC instructions, even though they have a syntax typical of an extension.

For all the instructions that are not part of the standard MSX-BASIC instructions, first check this page: MSX-BASIC Extensions.

A few instructions are standard instructions while being at the same time linked to a specific MSX-BASIC extension. The most obvious case is COPY added by the Disk BASIC extension and also present on all MSX2 (and later) computers as a graphical instruction.

Most MSX-BASIC Reserved Words are used by Disk BASIC, and you can divert some of them to create new instructions.
