User-Selected Computer ID

How do i get the user to enter an id?

Spoiler

term.clear()
term.setCursorPos(1, 1)

rednet.open("back")

io.write("Enter a Messege: ")
m = io.read()
io.write("Enter PC ID: ")
i = io.read()

rednet.send(i, m)

^^^that code doesn't work^^^

How do i fix it?

try rednet.send(tonumber(i), m)

You must use tonumber() to change the string to a number.

term.clear()
term.setCursorPos(1, 1)
rednet.open("back")
io.write("Enter a Message: ")
m = io.read()
io.write("Enter PC ID: ")
i = tonumber(io.read())
rednet.send(i, m)

Thanks sooo much :mellow:/>/>
It works now.
I read about the tonumber function but i thought you could only use it like this

x = "blah"
tonumber(A NUMBER HERE)
print(x)

But any way, thanks again. ;)/>/>

EDIT:

BTW sorry i didn't use the

 tags...

One more thing, can i make a program to display text on monitor?

monitor right hello
[/code

obviously doesn't work.

you have to redirect the output:
local screen=peripheral.wrap(side)
term.redirect(screen)

Not sure whether that is correct, i don't know the monitors well

do i put that inside the hello program or inside a different file (i.e show.lua/show)?

and what do you mean by screen in "term.redirect(screen)"?
