MOVEADDR Examples

Example 1:

DIM1	DIM	1
FORM1	FORM	1
INT1	INTEGER	1
PTRDIM	DIM	^
PTRFORM	FORM	^
PTRINT	INTEGER	^
PRTVAR	VARLIST	^
PTRDIM2	DIM	^
VARLIST	VARLIST	DIM1,FORM1,INT1
.
	MOVEADDR	DIM1,PTRDIM

	Variable	PL	FP	LP	Contents
Before:	DIM1	1	1	1	A
	PTRDIM				N/A

After:	DIM1	1	1	1	A
	PTRDIM				Address of DIM1

After this instruction was executed, any further PL/B instructions that referenced PTRDIM would perform as if they were referencing DIM1. Thus if we MOVEd 'A' to PTRDIM or DIM1, the result would be the same.

Example 2:

MOVEADDR

PTRDIM,PTRDIM2

(DIM Pointer to DIM Pointer)

	Variable	Contents
Before:	PTRDIM	Address of DIM1
	PTRDIM2	N/A

After:	PTRDIM	Address of DIM1
	PTRDIM2	Address of PTRDIM

Thus, any further PL/B instructions that referenced PTRDIM or PTRDIM2 would perform as if they were referencing DIM1. Thus if we MOVEd 'A' to PTRDIM, PTRDIM2 or DIM1, the result would be the same.

Example 3:

MOVEADDR

FORM1,PTRFORM

(FORM to FORM)

	Variable	PL	Contents
Before:	FORM1	5	ХХХ43
	PTRFORM		N/A

After:	FORM1	5	ХХХ43
	PTRFORM		Address of FORM1

Thus, any further PL/B instructions that referenced PTRFORM would perform as if they were referencing FORM1. Thus if we MOVEd '123' to PTRFORM or FORM1, the result would be the same.

Example 4:

MOVEADDR

INT1,PTRINT

(INTEGER to INTEGER)

	Variable	PL	Contents
Before:	INT1	2	0x135
	PTRINT		N/A

After:	INT1	2	0x135
	PTRINT		Address of INT1

Thus, any further PL/B instructions that referenced PTRINT would perform as if they were referencing INT1. Thus if we MOVEd '256' to PTRINT or INT1, the result would be the same.

Example 5:

MOVEADDR

VARLIST,PTRVAR

(VARLIST to VARLIST)

	Variable	Contents
Before:	VARLISTX	N/A
	PTRVAR	N/A

After:	VARLISTX	N/A
	PTRVAR	Address of VARLISTX

After this instruction was executed, any further PL/B instructions that referenced PTRVAR would perform as if they were referencing the variables defined in VARLISTX. Thus, if we UNPACKed a 'null' variable into PTRVAR or VARLISTX, the result would be the same.

Example 6:

BUTTON1	BUTTON
BUTTON1P	BUTTON	^
.
	MOVEADDR	BUTTON1,BUTTON1P

	Variable	Contents
Before:	BUTTON	N/A
	BUTTON1P	N/A

After:	BUTTON1	N/A
	BUTTON1P	Address of BUTTON1

After this instruction was executed, any further PL/B instructions that referenced BUTTON1P would perform as if they were referencing the object BUTTON1.
