Limiting the number of characters per line in a scrolling field?

[Eric Chatonet]

Hi Glen,

One liner handler in the script of your field (if you please) :

on keyDown pKey
   if (pKey is an integer) and (the number of chars of the selectedLine 
< 5) then pass keyDown
end keyDown

Best regards from Paris,

PS. My ears don't like beep ;-)

No need exiting: nothing else can happen!
