#98659 - Allocate 2 bytes to a floating pointer
Hello all guys
I want to allocate 1 word(2 bytes) to a pointer
Assume in one case Pointer=0CAFFH
what is the best choice:

1).

mov dptr,#Pointer
clr a
movc a,@a+dptr
mov high,a
.....
..... ;it doesn't change dptr value
inc dptr
clr a
movc a,@a+dptr
mov low,a
.....
.....
Pointer: DB 0CAh,0FFH
Pointer1: ....
Pointer2: ....


2).


Hpointer equ 0CAH
Lpointer equ 0FFH

mov pointer,Hpointer
......
......
mov pointer,Lpointer

In this case i must use up to 200 equivalent such as H1pointer....

3).

mov pointer,#high(0CAFFH)
.....
.....
mov pointer,#low(0CAFFH)

Or is there another way?
Thanks
Reza
