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>
