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.
