Note: If factor 1 equals the key of the current record or if factor 1 is not specified,
the key comparison takes place at the Data Management level; otherwise, it takes
place within the RPG/400 program. If the file being read is defined as update and
the compare is by RPG, a temporary lock on the next record is requested and the
search argument is compared to the key of that record. If the record is already
locked, the program must wait until the record is available before obtaining the temporary
lock and making the comparison. If the comparison is unequal, the recordnot-
found indicator is turned on, and the temporary record lock is removed. If no
lock (N in position 53) is specified, a temporary lock is not requested. |
