!   If the last RMS operation issued was a $FIND, or if the

!   (i.e., "partial" record), then we must skip a record and
!   position ourselves to the next one.  In all other cases
!   (i.e., the last JSYS was a $OPEN or $GET), we are
!   already positioned at the correct place.
!
!   This module also must insure that the current record's
!   starting address is maintained correctly.  This
!   procedure varies depending upon the current file
!   context.  For instance, if two successive $FINDs are
!   done, a record must be skipped and its length added to
!   the starting address of the last record.  If the last
!   record access was a "partial" record, the length of that
!   record must be added to its starting address, then the
!   rest of the record must be skipped and the amount that
!   was skipped also added into the current RFA address.
!
!   For normal conditions (i.e., a $FIND is done after a
!   successful $GET or $FIND), then the length of the last
!   record (i.e., current record to the user) must be added
!   to its starting byte number to produce the address of
!   the next record, which then immediately becomes the
!   current record.  This entire process must also be done
!   for sequenced files, except all bytes are in terms of
!   words and the line-number must be accounted for in
!   certain calculations.
