S(shared) is a I-bit field that. if 1, indicates that the overlay will have to be loaded at the same location as the overlay indicated in the SHARED OVERLAY INDEX field.

The SHARED OVERLAY INDEX subfield, present if bit S in the SA subfield is 1, points to a previously defined OVLDEF record and indicates that the segments with same seqment names and class names and/or the groups with same names in the two overlays must be loaded at the same location.

The ADJACENT OVERLAY INDEX subfield, present if bit A in the SA subfield is 1, points to a previously defined OVLDEF record and indicates that the seqments and/or qroups in the overlay defined by the current OVLDEF record must be loaded adjacent to the ones with the same names in the indicated overlay.
