and thank you for helping

Currently, the script will wait for a redstone state change, then error out due to spelling mistakes.

This block here:

while true do
event = os.pullEvent()
if event == "redstone" then
break
end
end

… could be re-written as just:

os.pullEvent("redstone")

Combining that with fixes for the other errors, we'd get:

os.pullEvent("redstone")
peripheral.call("top", "write" , "Hello world")  -- Assuming a monitor is above, writes "Hello world" on that
sleep(10)
term.clearLine()  -- Clears the current line on the computer's own display
sleep(10)
term.setCursorPos(1,1)  -- Moves the cursor on the computer's own display

If this differs from what you "want", then it might pay to explain what exactly that is and what said differences are.
