Description
MemoryDisk BASIC is a BASIC extension that uses a part of the MSX memory to create a RAM-Disk or Memory Disk. This disk is recognized as MEM: and is lost when you reboot or turn off the computer.
According the MSX-BASIC version of the computer, the size of the Memory Disk can differ. See CALL MEMINI for details.
Versions
There are 2 versions of this extension:
- Version 1 is available on a few Toshiba MSX1 machines: the HX-20 (all versions), HX-21 (Japanese version), HX-22 (Japanese version), HX-31 and HX-32
- Version 2 is available on all MSX2 and higher computers. All instructions from version 1 were integrated in MSX-BASIC 2.0 except for CALL MEMOFF
Instructions (general info)
Both versions extend the 6 following instructions: CLOSE, LOAD, MERGE, OPEN, RUN and SAVE.
