ROM-DOS Commands
This section provides descriptions of the ROM-DOS commands listed in
the following “ROM-DOS vs MS-DOS” table. Each entry includes an
explanation of the command's purpose, the command entry syntax,
remarks, and examples.
Each command also has a label to designate whether it is an internal or
external command. Internal commands are part of the command
processor program, COMMAND.COM. These functions are available
only while COMMAND.COM is running. External commands are
actually stand-alone utility programs. They are independent from
COMMAND.COM. Internal commands that are unique to
CONFIG.SYS processing are also identified. These commands can be
used only in a CONFIG.SYS file.
