Rednet relaying messages

Hey I'm attempting to relay Rednet messages over 64 blocks with this code

function relay()
 rednet.open("right")
 local event, param1, param2, param3 = os.pullEvent("rednet_message")
 If param1 == "88" then
  rednet.broadcast(param2)
  relay()
 else
  relay()
 end
end

relay()

The message isn't passing throug, not making it to the last computer.
What's wrong here is it the if statement

I think you are looking for rednet.receive() instead of os.pullEvent().
If you do use os.pullEvent(), I believe that the first parameter would come across as an integer/number. Try removing the quotes from "88", and it might work. Not sure what you have on the sending end though.

Yes, the problem is that the id (param1) is a number and you are comparing it to a string. Remove the quotes from the "88" and it should work.
Also, DON'T USE RECURSION TO MAKE LOOPS. It will overflow the stack after some time, use actual loops instead.

I tried receive before but it didn't work so I tried os.pullEvent
I'm trying to make a program that you can type bomb on a pc to send a message to turtles 200 blocks up to start bombing (it's our company's defense/offense system for a nuclear war coming soon)
I had it written

function relay()
 rednet.open("right")
 local sID, message, MSGDis = rednet.receive()
  rednet.broadcast(message)
end

The MSGDis var is actually capturing the distance the message is being sent.

The output from rednet.receive() is the sender id, the message, and the distance the message was sent.

If you are sending additional information in the message that you need to use you will need to split it out of the message. rednet.send() only sends the ID and 1 message string.
