Handlers and Scope

Although Rob gave you the full answer, the simple answer is "change
'function' to 'on' and you're done". :-)

That is, a function called DoMyStuff:

function DoMyStuff pWhatToDo
  -- does a bunch of stuff and doesn't return a value
end DoMyStuff

which is called like:

  get DoMyStuff("bark")

  -- I used "get" since it doesn't need to return a value, wheras
  -- it's better to use "put" when you want the returned value

becomes a handler when you change 'function' to 'on':

on DoMyStuff pWhatToDo
  -- does a bunch of stuff and doesn't return a value
end DoMyStuff

and is called like this:

  DoMyStuff "bark"
