NOOB Question! need help with IRremote library

Thank you very much for your help! I really like this new hobby and prefer to figure it on my own so this, to me, is an act of desperation XD. I was on the rite track, just having trouble getting arduino to recognize the remote code specific to the button I intend to use.

I was thinking something like this,

void loop() {
if (irrecv.decode(&results=A90)) { //or 149 or whatever the sony power button is?...
digitalWrite(relay1, HIGH);
irrecv.resume(); // Receive the next value
}
}

Tried a cpl other variations of that and usual error is "A90" not defined.

And again, Thank you very much for your help and look forward to completing this project. :wink:
