(T6) X is an EXTERNAL INDEX. The TARGET is the byte whose address is (eventually qiven by) the External Name identified by the

INDEX.

(T7) X is a FRAME NUMBER. The TARGET is the byte whose 20-bit address is (X*l6).

The following nomenclature is used to describe a TARGET:

TARGET:	SI«seqment name»	,<displacement>	(T0]
TARGET:	GI«qroup name» ,<displacement>		(TIl
TARGET:	EI«symbol name»	,<displacement>	[T21
TARGET:	<FRAME NUM9ER>,<displacement>		(T3]
TARGET:	SI«seqment name»		(T41
TARGET:	GI«qroup name»		(T51
TARGET:	EI«symbol name»		(T~l
TARGET:	<FRAME NUMBER>		(T71

Here are some examples of how this notation can be used:

TARGET: SI(CODE) ,1024		The	l025th		byte in
		the	segment		·CODE"
TARGET: GI(DATAAREA)		the	location			in MAS of
		a qroup called -DATAAREA d
TARGET: EI(SIN)		the	address		of the external
		subroutine			·SIN"
TARGET: 8000H,24H		MAS	location			800248
TARGET: EI(PAYSCHEDULE) ,24		the	24th	byte		followinq	the
		location		of	an
		EXTERNAL data				structure
		called dPAYSCHEOULE-
Altnouqh -TARGET:	SICA)"	and	"TARGET:			SI(A) ,0"	both specify

the same TARG8T, their use can have different effects, as is discussed below in the section on intermediate values in fixup arithmetic.

FRAME - Every 8086 memory reference is to a location contained within some FRAME; where the FRAME is desiqnated by the content of some

seqment register. In order for R&L to form a correct, usable memory

reference, it must know not only what the TARGET is, but also with

respect to which FRAME the reference is heinq made. Thus every fixup specifies such a FRAME, in one of 5 ways (F0, ••• ,F5) described below. Some ways use a datum, X, which is an INDEX-or-FRAME-NUMBER, as above. Other ways require no datum.

This is not the case of an 8089 self-relative reference. The

reference may be to any location within an 8089 proaram,

independently of FRA~E. The only restriction is that the
