Clear the screen on program ?

hi, i want to ask about my startup program… it just a regular door locking and the problem is after i enter the password it's open the door but it doesn't clear the screen

ex:
Please enter the password:

(after i enter the correct password)

Please enter the password:
****
Please enter the password:
_

any idea to clear previous text ? and where i should put them ?

here's my script

Spoiler

function pass()
textutils.slowPrint("Welcome… please enter the password:")
x = io.read()
if x == "the password" then
redstone.setOutput("back",true)
sleep(2)
redstone.setOutput("back",false)
pass()
else
pass()
end
end
pass()

term.clear()

will clear the terminal screen so put it before slowprint
you might also want to put a term.setCursorPos(1,1)
behind or before term.clear() as it sets the cursor back to the top left position

oh thanks…

but it makes the else text gone
ex.
Pass:

(i typed the wrong pass)

You entered the wrong password.

but with term.clear it will be restarted to 'pass:' not to 'You entered the blablabla'
any idea to fix it ?

Do this:

while true do
term.clear()
term.setCursorPos(1,1)
term.setCursorBlink(true)
textutils.slowWrite("Welcome... nPassword: ")
local ePass = read("*")
term.clear()
term.setCursorPos(1,1)
if ePass == "the password" then
redstone.setOutput("back",true)
sleep(2)
redstone.setOutput("back",false)
end
end

P.S: 'n' is a new line, it won't show.

There's an APIs section where you can see all the commands. Most of them are for computers and turtles, only the turtle api is for turtles only.
