  Prototype in        doshk.h

  Remarks             remove a CED installable command. The command
                      parameter should be terminated by a CR.

  Return value        returns TRUE if successful, FALSE otherwise. If
                      unsuccessful, _doserrno will contain the error
                      code:

                      If CED is not installed, _doserrno & 0xFF00 will
                      return 0xFF00.
