This example shows the difference in storage allocation a SYNC
clause can make. A field of USAGE type LONG occupies four bytes
of storage (the equivalent of one longword):
DTR> DEFINE RECORD NOSYNC_REC USING
DFN> 01 TOP.
DFN> 03 ONE PIC X.
DFN> 03 TWO LONG.
DFN> ;
[Record is 5 bytes long.]
DTR> DEFINE RECORD SYNC_REC USING
DFN> 01 TOP.
DFN> 03 ONE PIC X.
DFN> 03 TWO SYNC RIGHT LONG.
DFN> ;
[Record is 8 bytes long.]
DTR>
