Help regarding program

Hi guys of computercraft!
I've been lurking around trying to find a program / make one myself for a couple of days so i decided to register and ask

Im trying to find a script / program that does this: A melee turtle that spins endlessly to the left and attacks each time it has spun 90 degrees.

Figured id look around and tried to do a while loop

"while true do –Always loop
–Turtle.turnleft()
turtle.attack()
end

But it seems to be doing nothing?

Moved to own topic.

Try this

while true do
turtle.turnLeft()
turtle.attack()
end

Keep in mind that Lua is case-sensitive…
