I don't know if you know this, but if you name your program startup it will run on startup (a.k.a. when you start the computer/turtle)

And then it's just to make a login program, theres a lot of simples one out there!

And so if you want to be able to have a limit amount of tries, you can use mine :D/>/> :

Now you'll have to edit this one ↑↑ to get it to do as you want when you fail the login, and to edit the limit amount of tries etc.
Currently it shutdown if you run out of tries, and it goes to the shell once you enter the correct password.

here i made a textbox type thing:
usage: textbox(label)
returns string or nil if you press ctrl to close it out


local function textbox(bartext)
term.setCursorBlink( true )
    local sLine = ""
local nPos = 0
local oW, oH = term.getSize()
local w,h=oW-4,math.floor(oH/2)
local sx,sy=4,math.floor(oH/2)
local function redraw()
  local nScroll = 0
  if sx + nPos &amp;gt;= w then
   nScroll = (sx + nPos) - w
  end
  term.setCursorPos(3,math.floor(oH/2)-1)
  write(string.rep("-",oW-5))
  term.setCursorPos(3,math.floor(oH/2)+1)
  write(string.rep("-",oW-5))
  term.setCursorPos(math.floor(oW/2)-math.floor(#bartext/2),math.floor(oH/2)-1)
  write(bartext)
  term.setCursorPos( sx, sy )
  term.write(term.write( string.rep(" ", w - sx + 1) ))
  term.setCursorPos( sx, sy )
  term.write(term.write( string.sub( sLine, nScroll + 1 ) ))
  term.setCursorPos(3,math.floor(oH/2))
  write("|")
  term.setCursorPos(oW-3,math.floor(oH/2))
  write("|")
  term.setCursorPos( sx + nPos - nScroll, sy )
end
redraw()
while true do
  local sEvent, param = os.pullEvent()
  if sEvent == "char" then
   sLine = string.sub( sLine, 1, nPos ) .. param .. string.sub( sLine, nPos + 1 )
   nPos = nPos + 1
   redraw()
  elseif sEvent == "key" then
	  if param == 28 then
    break
   elseif param == 203 then
    if nPos &amp;gt; 0 then
	 nPos = nPos - 1
	 redraw()
    end
   elseif param == 205 then  
    if nPos &amp;lt; string.len(sLine) then
	 nPos = nPos + 1
	 redraw()
    end
   elseif param == 200 or param == 208 then
    if _tHistory then
	 if param == 200 then
	  if nHistoryPos == nil then
	   if #_tHistory &amp;gt; 0 then
	    nHistoryPos = #_tHistory
	   end
	  elseif nHistoryPos &amp;gt; 1 then
	   nHistoryPos = nHistoryPos - 1
	  end
	 else
	  if nHistoryPos == #_tHistory then
	   nHistoryPos = nil
	  elseif nHistoryPos ~= nil then
	   nHistoryPos = nHistoryPos + 1
	  end	 
	 end
	 if nHistoryPos then
					 sLine = _tHistory[nHistoryPos]
					 nPos = string.len( sLine )
				    else
	  sLine = ""
	  nPos = 0
	 end
	 redraw()
			    end
   elseif param == 14 then
    if nPos &amp;gt; 0 then
	 sLine = string.sub( sLine, 1, nPos - 1 ) .. string.sub( sLine, nPos + 1 )
	 nPos = nPos - 1	
	 redraw()
    end
   elseif param == 29 then
    term.setCursorBlink( false )
    return nil
   end
  end
end
term.setCursorBlink( false )
term.setCursorPos( w + 1, sy )
return sLine

–snipped code–

Cool! So how does it work? How do we use it?
Is it just textbox("the text I want to be in a textbox")?
Or what do we use it for?

thx!
i will try!
and then a other question, i want 2 if statements and then a else statement.
this is the code

————————————————-
if input == ""on"" then
term.clear()
term.setCursorPos(12,4)
print("TURNING ON NUCLEAR REACTOR")
sleep(3)
rs.setOutput("back", true)
shell.run("nuclear") – same program so you can turn it off again
if input == "off" then
term.clear()
term.setCursorPos(12,4)
print("TURNING OFF NUCLEAR REACTOR")
rs.setOutput("back', false)
shell.run("nuclear")
end
else

term.clear()
term.setCursorPos(12,4)
print("COMMAND NOT RECONIZED!")
sleep(3)
shell.run("nuclear")

if input == ""on"" then
term.clear()
term.setCursorPos(12,4)
print("TURNING ON NUCLEAR REACTOR")
sleep(3)
rs.setOutput("back", true)
shell.run("nuclear") -- same program so you can turn it off again
if input == "off" then
term.clear()
term.setCursorPos(12,4)
print("TURNING OFF NUCLEAR REACTOR")
rs.setOutput("back', false)
shell.run("nuclear")
end
else

term.clear()
term.setCursorPos(12,4)
print("COMMAND NOT RECONIZED!")
sleep(3)
shell.run("nuclear")
end

More tips: make input into lower case so it will not be case sensitive (unless you want it to be - because right now, if you were to type On, ON or oN it will not activiate - It only will accept 'on')

Spoiler


input = string.lower(read())

if input == "on" then
  term.clear()
  term.setCursorPos(12,4)
  print("TURNING ON NUCLEAR REACTOR")
  sleep(3)
  rs.setOutput("back", true)
  shell.run("nuclear") -- same program so you can turn it off again
elseif input == "off" then
  term.clear()
  term.setCursorPos(12,4)
  print("TURNING OFF NUCLEAR REACTOR")
  rs.setOutput("back', false)
  shell.run("nuclear")
else
  print("COMMAND NOT RECOGNIZED!")
  sleep(3)
  shell.run("nuclear")
end
