EXTERNAL COMMAND

A DOS command that is "separate from" the COMMAND.COM program and processed by
executing a separate program rather than an internal subroutine. An EXTERNAL 
COMMAND is contrasted with an INTERNAL COMMAND. Some external commands are 
executed by programs that you buy separately, like LOTUS. One external command
with a confusing name is COMMAND, which tells the computer to execute the 
COMMAND.COM program (see the COMMAND.COM definition for more information).

The external commands are:
