The RLSE subroutine sets the partial release indicators to 'on' in the JFCB if the number of extents in the data set is less than a fixed value (8 in the example). It sets the partial release indicators in the JFCB to 'off' if the number of extents in the data set is equal to or greater than a fixed value (8 in the example). Partitioned data sets are not processed because they can be opened many times to write one new member for each OPEN-CLOSE macro sequence.
