[Question] Clear text and make new text in its spot?

I tried something like
print "Hello"
cls
print "potato"
cls
print "cow"

But apparently it doesnt work like that. So I found out about term.clear. That does the job but how do I set a delay to it?

Edit: Found out about os.sleep, sorry!

You Are programming in lua. That you need is : term.setCursorPos(1,1) to set the Mouse at the top left corner.
Term.clear() is clearing the screen, and term.setCursorPos() is setting the Mouse position..


cls is not existing in lua/minecraft. So if you want any other help, type 'help (program)'

Here's how you'd do something like that:

function cls() -- This is optional, you could just type 'term.clear()' but I suppose it's more comfortable for you to do this.   '
term.clear()
end

cls() -- Executes the function cls()
term.setCursorPos(1, 1) -- Sets the cursor to the upper left corner
print("Hello")
sleep(1)  -- Computer waits 1 second before it moves on
cls()
term.setCursorPos(1, 1)
print("potato")
sleep(1)
cls()
term.setCursorPos(1, 1)
print("cow")
sleep(1)

Thanks guys!

to make the code smaller you can do this

function cls(string)
  term.clear()
  term.setCursorPos(1,1)
  print(string)
end

cls("Hello")
sleep(1)
cls("potato")
sleep(1)
cls("cow")
