Description
Kanji BASIC extension comes with the Kanji Driver. These extended instructions can be found in the Kanji Driver ROM. Most of these instructions are actually useful only on Japanese machines that have a Kanji-ROM (128kB if JIS1, 256kB if JIS1+JIS2).
Kanji BASIC is available on
- the MSX2+ and MSX turbo R computers
- the ASCII Nihongo MSX-DOS 2 cartridge
- the Sony HBI-J1 cartridge
Instructions (general info)
Kanji BASIC comes with 14 new instructions. The MSX-BASIC instruction PUT KANJI, available on all MSX2 and higher computers, can be seen as a related Kanji BASIC instruction.
Notes:
- CALL can be replaced by the character underscore (_). A space is not required after this character. See CALL for more info.
- This BASIC extension is optional on MSX2 as it requires one of the cartridges mentioned above. The 14 new instructions become officially part of the standard since MSX2+.
