Command Files 

Together with the familiar User Defined Commands (UDCs), Command Files
make up the facility called user commands.

Like UDCs, they let the user define commands which can then be executed
by entering the name of the Command File.  Like UDCs, Command Files are
created with text editors, and may be kept as numbered or unnumbered
ASCII files.

Unlike UDCs, Command Files do not have to be cataloged with the
:SETCATALOG command.
