ROM-DOS 6.22 Command Summary
For information on ROM-DOS commands, please refer to a commercially available
ROM-DOS user guide.
Following are brief descriptions of ROM-DOS commands, including batch file commands.
Note: The external ROM-DOS files loaded on the MX1 by LXE (and supported by LXE) are
marked with an asterisk in the table that follows. ROM-DOS internal commands are a
part of the ROM-DOS operating system.

not part of the LXE installed and LXE supported file load.
