Search for a specific word?

So I'm trying to make a system with 4 computers where there is a sender, two receivers and a 'server'. The sender rednet.send's a string to the 'server' containing one of the receiving computers ID's. Is there a way for the 'server' to check the string for certain text (in this case the receiving computers ID) and, say, store it in a variable(e.g: ReceivingID). Then the server could do: rednet.send(ReceivingID, "String"). This is just a guess, is there any way at all for me to do this? Thanks for reading, Imprivate

Well if you're just sending the ID's then it is easy

--# The computer that sends
local id = 101
rednet.send(<serverID>, id)

--# Server Computer
local id, receiverID = rednet.receive()
receiverID = tonumber(receiverID) -- Converts receiverID to a number

I wanted the ID in a string but oh well. I can always do read() and save that as the ID, I was just wondering if there was a way to check strings for certain text. Thanks anyway for you reply :)/>

id = tostring(id)

Wouldn't that just check for the word "ID"? Oh well, this is still really useful, thanks! :)/>

No, tostring() converts numbers to strings. tonumber() does the opposite, as long as the string represents a valid number.
