                      9: .sh DESCRIPTION
                     10: NOCLOSE is used to update the system catalogs
                     11: for a relation just as CLOSER does,
                     12: but without closing the relation.
                     13: If a program repeatedly OPENR's and CLOSER's
                     14: a relation so that the system catalogs will be
                     15: up-to-date for use by other programs,
                     16: NOCLOSE can be used to eliminate the overhead
                     17: of physically opening and closing relations
                     18: and still achieve the same results.
