FUNCTION
    The basic iteration function with which to find all records in the

    Each ID is a 32-bit Key which uniquely identifies one record.
    The INVALID_ID is special, and indicates the end-of-list.

INPUTS
    last_ID - previous displayinfo identifier
              or INVALID_ID if beginning iteration.

RESULT
    next_ID - subsequent displayinfo identifier
              or INVALID_ID if no more records.
