Tazntex,
You are forgetting something I think.
When you press a button, your IF statement works only WHILE you are pressing the button.
When you do NOT press a button, your ELSE statement works continuously.
This is why "you think" that you see no change; because it happens so fast when you hit the button down and release it.
I think you should set an IF statement with the first button press, and keep it that way until you press it second time. Like a flip flop.

Yes Joe that is a typo in the copy and paste. When I read all the replies with example code how are ya'll inserting the code block whereas I am just copying and pasting my code to this reply. I am assuming, which I don't like to do, that under additional options I could attach my questionable code.
What does the DEC mean and do? In the manual I understand it to be Decimal as in MYDATA would be recieved as a decimal. After reading many post on Manchester, I would think I would only be using Binary, but it would seem in the end Binary, Decimal and Hex would all be the same.
loop1:
SERIN2 PortA.1,84,[DEC address1,DEC ADDRESS2,DEC MYDATA1,DEC MYDATA2]
Return
end
Sayzer, in the flip/flop method you are speaking of, I can see how to turn an output on/off with the toggle command, but I do not understand how I could press the button on the tx and the output would come on the receiver but would have to release the button and press again to make it go off. As I have it using the toggle command as long as I am pressing the button on the tx the rx output just cycles on and off. Well I will keep reading the PBP manual maybe thats in there and I have missed it. By the way I am using the PBP v2.50 with the update installed.
Many, many thanks to all for your help and patience.

It actually means that SERIN (or whatever) will wait until it receives x characters to be interpreted as a decimal.What does the DEC mean and do? In the manual I understand it to be Decimal as in MYDATA would be recieved as a decimal.
For instance:
SERIN xxx,xxx,xxx, [ DEC1 x ]
Waits for a single character between "0" and "9", preceeded by a character that's not between "0" and "9" and followed by another character that's not between "0" and "9".
Another for instance:
SERIN xxx,xxx,xxx, [ DEC5 x ]
Waits for 5 consecutive characters that are each between "0" and "9", preceeded by any character that's not between "0" and "9" and followed by another character that's not between "0" and "9".
So, the DEC (or HEX or BIN) modifier actually does 'parsing' of an input stream for you.
HEX would wait for ASCII characters between "0" and "9" in addition to "a" (or "A") through "f" (or "F").
BIN would only wait for "0" and "1".
For reference..."0" = ASCII code 48 ($30), "9" = ASCII code 57 ($39), and so on. Just so we're on the same page here.

Mostly it means I have an easier time dealing with decimal numbers, than binary, as Jeremy pointed out you can use hex, binary, or decimal, it's all good.
Your receiver doesn't just stop because you are still holding the button, and besides your transmitter is sending a signal, not some d/c value, additionally when you go the R/F route, this is where switch debouncing comes in and should be on the transmitter I think. I think the transmitter program should send a packet of data, size determined by you, for each valid button press and not just keep sending continuously, otherwise scratchy switches will corrupt your data.

ok, how come if i use this on the receiver:
if mydata1=%01100101 then pause 50
if mydata1=%01100101 then
high 4
else
low 4
endif
And with this clip on the transmitter:
transmit:
serout serpin,N9600,[$55,$55,$55,$55,$55,$AA,$AA,$AA,$AA,$AA,synch,addr ess,address,keydata,keydata,chk_sum]
if keyin = nokey then x2
goto findkey
x2:
high dgood
keydata = %00000000
serout serpin,N9600,[$55,$55,$55,$55,$55,$AA,$AA,$AA,$AA,$AA,synch,addr ess,address,keydata,keydata,chk_sum]
goto findkey
Why is it that by transmiting to the receiver =%01100101 by pressing the button then once I release the button the transmitter sends keydata = %00000000 which I would think the ELSE would then turn PORTB.4 LOW, but it doesn't. Only when I press another button which activates the other three outputs which are using IF/THEN, ELSE. Then and only then will PORTB.4 go LOW, but the next output comes on and stay on like PORTB.4. Now the outputs I am toggling work just fine. Hopefully I am making some sense, and the folks with the white coats won't come get me
Thanks again, Ya'll have been a great help

On the receiver end change to SERIN2.
Have it wait for the "synch" and use the time out modifier. The time out modifier will take place of the "else".
So the reciever is "waiting" for the synch, if it does not get in in the specified time, the program will jump to where ever.
You do not need to send keydata = %00000000 . Once the receiver does not see the synch it will time out and go on.
I agree with Joe, debounce on the receiver end. Here is a simple but not so efficient way one of my kids debounced with a radio using SERIN.
The code waits for the number 9 and writes the next bit to a variable. 9 is the synch in this case. Then if the variable = 3 enough times then another piece of code executes. You will see the the next piece is called "send". He was doing a relay project. If the 9 was not seen the program went back to looping, if the 9 and 3 was seen the program sends something out to the next receiver.
He debounced the heck out of it
Code:LOOP: SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D1 GOTO LOOP D1: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D2 GOTO LOOP D2: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D3 GOTO LOOP D3: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D4 GOTO LOOP D4: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D5 GOTO LOOP D5: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN SEND GOTO LOOP D6: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D7 GOTO LOOP D7: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D8 GOTO LOOP D8: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D9 GOTO LOOP D9: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D10 GOTO LOOP D10: PAUSE 50 SERIN PORTC.4,T2400,[9],net IF net = 3 THEN SEND GOTO LOOP D11: SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D12 GOTO LOOP D12: SERIN PORTC.4,T2400,[9],net IF net = 3 THEN D13 GOTO LOOP D13: SERIN PORTC.4,T2400,[9],net IF net = 3 THEN SEND GOTO LOOP
