APPENDIX L

[continue/next section] [MAIN/Introduction] [table of contents]

DISK COMMAND SUMMARY

NOTE: Follow this link for the lynx-friendly version.

This appendix lists the commands used for disk operation in C128 and C64 modes on the Commodore 128. For detailed information on any of these commands, see Chapter V, BASIC 7.0 Encyclopaedia. Your disk drive manual also has information on disk commands.

The new BASIC 7.0 commands can be used only in C128 mode. All BASIC 2.0 commands can be used in both C128 and C64 modes.
