EXTADDR

An EXTADDR is 32 bits. You can store the address of any of your processes’ data in

an EXTADDR pointer.

Example 10-7. CBADDR and CWADDR

INT sa = 'P' := [1,2,3,4]; ! Address type of sa is CWADDR

STRING sb = 'P' := ["ABCD"]; ! Address type of sb is CBADDR

PROC p;

BEGIN

LABEL lab1;

SUBPROC subp1;

BEGIN

CWADDR cw;

CBADDR cb;

ENTRY ent1;

ent1:

lab2:

cw := @subp1; ! Address type of @subp1 is CWADDR

cw := @lab1; ! Address type of @lab1 is CWADDR

cw := @lab2; ! Address type of @lab2 is CWADDR

cw := @ent1; ! Address type of @ent1 is CWADDR

cw := @sa; ! Address type of @sa is CWADDR

cb := @sb; ! Address type of @sb is CBADDR

END;

lab1:

END;

Example 10-8. EXTADDR Declarations

INT .EXT i;

STRING .EXT s;

INT .EXT g = 'SG' + 0;

REAL .EXT r;
