How do you make a text Just go invisible When Somebody Reads It?

I dont think its possible to make it go away, so just add a bunch of lines.

print("welcome")
while true do
print(" ")
end
break
whatever
i do more complicated stuff i dont do easy stuff anymore XD

but why would you want to do tht and make it look good? its the output for studio (its for debugging usually) and playing a game with printing doesnt show up anywhere. its only in the output in studio.
