Code:
--Quick and dirty LUA text input example
--by: Dark Killer

--You are free to modify and/or implement this in your own projects, all I ask in return is that you credit me.

--Controls:
--  Up/Down: select character
--  X: add character
--  R: space
--  L: backspace
--  Start: submit   

function Controls.waitpadup() --pauses execution untill all buttons are released
   pad=Controls.read()
   while pad:select() or pad:start() or pad:up() or pad:right() or pad:down() or pad:left() or pad:l() or pad:r() or pad:triangle() or pad:circle() or pad:cross() or pad:square() do
      screen.waitVblankStart()
      pad=Controls.read()
   end
end

   a=65
   c=""
   while true do
      screen:clear(Color.new(0,0,0))
      screen:print(100, 100, "what is your name?", Color.new(0,255,0))
      if a<65 then
         a=90
      end
      if a>90 then
         a=65
      end
      b=string.char(a)
      screen:print(118, 110, c..b, Color.new(0,255,0))
      pad = Controls.read()
      if pad:up() then
         a=a+1
         Controls.waitpadup()
      end   
      if pad:down() then
         a=a-1
         Controls.waitpadup()
      end
      if pad:cross() then
         c=c..b
         Controls.waitpadup()
      end
      if pad:r() then
         c=c.." "
         Controls.waitpadup()
      end
      if pad:l() then
         c=string.sub(c, 1, (string.len(c)-1))
         Controls.waitpadup()
      end
      if pad:start() then
         screen:print(100, 140, "hello," .. c..b .. "!", Color.new(255,0,0))
         Controls.waitpadup()
         screen.waitVblankStart()
         screen.flip()
         while true do
            screen.waitVblankStart()
         end
      end
   screen.waitVblankStart()
   screen.flip()
   end

This is very intriguing, what i'd like to know is if there is a way to save the name to a file, .lua, .txt whatever. If there is, how does one go about doing it? (i have been unsuccesful in my searching of it.
