SIMPLE question

[ngeronikolos]

Duncan,

What I was thinking...

portA PORTB
% 00000000 / 00001000

<0> PORTB.0 <1>PORTB.1 .... <8>PORTA.0
Let's say that this is my word that Contains PORTA+PORTB that I have to check.
The followings are correct???
----------------------------------------------
w0 var word
L var byte
H var byte

L = PORTB
H = PORTA
w0.LowByte = L
w0.HighByte = H

If w0 > 1 then
I WILL READ THE w0
endif

---------------------------------------------------

Thanks

If that is what you want to do, you could use Darrel's trick with EXT

@PORTS = PORTA
PORTS VAR WORD EXT  ; PORTS = PORTB:PORTA

; in middle of program

if PORTS > 1 then ....

(Don' t forget to mask the unused bits of PORTA if they might not be 0)
