Command
Type
Purpose
Start a new Command Processor.
Syntax
COMMAND[ device ][/E: number ][/K: filename ][/P][/C string ][/ MSG ]
Remarks
This command starts a new copy of the ROM-DOS Command Processor. The
Command Processor is the program that has all the internal DOS commands in it.
Starting a new Command Processor will also produce a new environment. The size
of the environment is 128 bytes by default, but can be changed using the /E switch.
Command and its arguments can also be used in a SHELL= statement in your
CONFIG.SYS Þle. See the full description of SHELL for more details.
Options
The device option speciÞes that COMMAND.COM should use a different device,
such as AUX, for input and output.
The /E:number switch sets the environment size. Number represents the size of the
environment in bytes. Number must be in the range from 160 to 32768. All other
values will be ignored and the default value of 256 will be used. ROM-DOS will
round the value entered up to the nearest multiple of 16.
The /K:filename option tells the command processor to run the speciÞed Þlename
and then display the ROM-DOS command prompt. It is not recommended that this
option be used in a CONFIG.SYS SHELL= statement.
The /P switch causes COMMAND not to exit, in other words, remain permanent.
The /P switch should only be used when command is used in a CONFIG.SYS
SHELL statement.
The /c string switch causes COMMAND to execute the command in string and
then terminate. The string command can be any internal or external command.
The /MSG option indicates that all error messages should be stored in memory.
This option is recommended only for diskette based systems. ROM-DOS keeps
