thanku archangel sir for replying.

now the basic purpose of my project is to turn a relay on or off using sirc(sony protocol).

for this i need to decode just two keysne for on and one for off.or maybe just one key that if a user presses a button 5v appear on output pin and if it presses the same button then it turns off!!this is one point...

the next point is that the above code is working for

if IRBUTTON >=0 and IRBUTTON < 255 then
 
 
but not working for 
if irbutton=16 then high sony led '16 is for channel up

it is not working for this the above command
this is the second point...


and the third point is that i dont understand this
One more thing, I think portB inputs default to weak pull ups on, turn them off in the option register.
EDIT: Nope default off. Easy to check with a hi impedance voltmeter though... cant understand this
