FUNCTIONAL DESCRIPTION:

    Main routine for arff.

    Causes command to be parsed.  Causes the RT-11 device image to  be
    opened.   Causes  the  appropriate action to be taken.  Causes the
    RT-11 device image to be closed.

FORMAL PARAMETERS:

    Argument_count.rg.v - The number of elements of Argument_text that
	are valid.
    Argument_text.rt.ra - The command line arguments.

IMPLICIT INPUTS:

    None.

IMPLICIT OUTPUTS:

    None.

ROUTINE VALUE:

    0, success.  (Unsuccessful exits are taken throughout the  program
    via the exit() routine.)

SIDE EFFECTS:

    May manipulate the RT-11 device image or  currently  mounted  file
    systems.
