-..----_.- -.

LOCATION: OFFSET or LOBYTE

P5EG: 51 (A) (thi sis the most common cho ice)

TARGET: SI(B) ,dl

or 51 (B) (see diaqram and discussion followinq LOCATE OPE~

LINK. OPERATION:

If L5EG B combines then the LINKER will modify all fixups of the above form by chanqinq SI(B) ,dl to SI(8) ,dl+d2
