I get the above error when I run the program and when I use tonumber (probabily incorect) get expected ")" at line 8.

Thanks in andvance

PS: the pastebin URL/code http://pastebin.com/zr1A6a9N remove the tonumber to see the error.

You didn't define x and t. You need to define them before using them.
Here's a modified version:


local tArgs = {...}
local printer = peripheral.wrap("left")
printer.newPage()
printer.setPageTitle(tArgs[1])
for y = 2, #tArgs do
  printer.setCursorPos(1,y - 1)
  printer.write(tArgs[y])
end

Yes. # is the lenght operator in lua, it gets the lenght of strings or tables. tArgs is a table with the passed arguments, so it's lenght is the number of arguments.
