Allows you to reject a call from another user while you are using
    Phone. A message indicating that the call has not been accepted
    is displayed on the caller's screen.

    The REJECT command accepts the optional parameter EXIT. If this
    parameter is specified, the EXIT command is invoked following
    the rejection. This feature allows you to set up a personalized
    DCL command that can reject a call and return to DCL without your
    intervention. Such a personalized command might appear in your
    login command file. For example:

    $ REJECT :== "PHONE REJECT EXIT"

    Format

      REJECT  [EXIT]
