MS-DOS Shell Spawns Two COMMAND.COMs (68990)

When you spawn a COMMAND.COM using the Command Prompt option in the
program list of MS-DOS Shell and run "MEM /P" if using MS-DOS version
5.0 or "MEM /PROGRAM" with earlier versions, it shows that you are
running two copies of COMMAND.COM. Why does it do this?
When you create and run a program item in MS-DOS Shell's program list,
Shell spawns a command processor to run the program that is listed in
the program item; therefore, when you have a program item that runs
COMMAND.COM, it spawns a command processor to run COMMAND.COM, and you
have two copies of COMMAND.COM running. This also occurs when you run
COMMAND.COM from the file list.
You can avoid running two copies of COMMAND.COM by using the SHIFT+F9
command to spawn a command processor instead of the program item in
the program list.
