    $ SFPURGE

This DCL command can be used to delete all but oldest and newest versions
of files corresponding to a given file-spec

    e.g.    $SFPURGE *.P/SINCE

will delete all but oldest and newest of each .P file made TODAY.

            $SFPURGE FOO.LIS

will delete all but oldest and newest versions of FOO.LIS. The "/SINCE"
qualifier can be given the same parameters as for DIR. You can also use
any other DIR switch, e.g. /EXCLUDE, but don't leave any spaces.
