literalMore Information

 The characters you want displayed to the user during execution
 of the command procedure.  Enclose the characters in each
 literal with quotation marks.

 Use a comma to separate two or more literals.  A comma used as a
 separator is not displayed to the user when the command
 procedure executes.

 To display a comma as part of a literal, include the comma
 inside the quotation marks enclosing the literal.
