Maybe you can try something like this: function listen() event.ignore("modem_message",listen) -- Do your thing event.listen("modem_message",listen) end

Please check out the wiki before posting here. WIKI I had a look and this is what i found. General stuff: http://ocdoc.cil.li/component http://ocdoc.cil.li/api How to controll the robot http://ocdoc.cil.li/api:robot How to arrange items in an inventory http://ocdoc.cil.li/component:inventory_controller You should also look for some lua tutorials if you are not familiar with it.

you only need 1 gpu bind your gpu to the first screen then use "io.write" to write "Computer Lab" Then bind it to the second screen. If you want to write a message to the first screen just bind the gpu to the first screen again. If you need to use 2 gpus then do the following. component = require("component") component.setPrimary("gpu","your gpu address") then just use io.write()
