monitor text

i want a text on a monitor but how do i do it can sombody help my?

First, Wrap it

local mon --# Create a variable for the monitor
for _, name in ipairs( peripheral.getNames() ) do -- Loop through all peripherals attached
	if peripheral.getType( name ) == "monitor" then -- Check if the peripheral type was a monitor
		mon = peripheral.wrap( name ) -- If it was the wrap it
		break -- And break from the loop
	end
end

Now it's simple, You can do this

mon.write("Hello World!")

Note that all the 'term' functions does work for monitors, So you can do this
mon.clear()
mon.setCursorPos(1,1)
mon.setTextColor(colors.white)
mon.setBackgroundColor(colors.black)
etc..

You can also use term.redirect, which will allow you to then use print() and write() and textutils.tabulate(), etc.
