SCAN mode: RANGE and UNIQUE are checked for statement errors, but DFSORT is not called.

STOP mode: DISPLAY is dependent on VERIFY. If the return code for VERIFY is 12 or 16, SCAN mode is entered; DISPLAY is checked for statement errors, but DFSORT is not called.

CONTINUE mode: COPY, SORT, and STATS are independent of each other. SORT is processed even if the return code for COPY is 12 or 16. STATS is processed even if the return code for COPY or SORT is 12 or 16.

Note that the return codes for one group of operators does not affect the other groups of operators.
