Constraining user input...

[Sarah Reichelt]

I don't know that this is a very elegant solution, but it works so it can
get you started. Put this in the script of your text entry field.

on keyDown theKey
  if the number of lines in me >= 3 and \
      the number of chars in line 3 of me >= 30 then
    beep
    exit keyDown
  else
    put word 2 of the selectedLine of me into theLine
    if the number of chars in line theLine of me >= 30 then
      beep
      exit keyDown
    end if
  else
    pass keyDown
  end if
end keyDown

Cheers,
Sarah
