NOSYNC / SYNC
- NOSYNC indicates that the SYNCHRONIZED
clause is syntax checked only. NOSYNC is the default value.
- SYNC indicates that the SYNCHRONIZED clause is compiled
by the compiler. The SYNCHRONIZED clause causes the position of a data item
to be aligned such that the right-hand (least-significant) end is on the natural
storage boundary. Extra storage is reserved adjacent to the synchronized item
to achieve this alignment. Each elementary data item that is described as
SYNCHRONIZED is aligned to the natural storage boundary that corresponds to
its data storage assignment.
