The version above works only if someHandler is a property. If you note out that line it fails.

It works fine if you declare someHandler as a global variable.

I think this demonstrates scope more clearly than using a Property (provided you don't need it to be a Property).

Take Care,

global someHandler

DoFirstHander()

someHandler(4)

call(double, 4)

DoMyHandler()

on double(aNumber)

return aNumber * 2

end double

------------------------------------------------------------

on call(someHandler, aValue)

someHandler(aValue)

end call

------------------------------------------------------------

on DoMyHandler()

someHandler(4)

call(double, 4)

end DoMyHandler

------------------------------------------------------------

on DoFirstHander()

set aValue to "3"

set someHandler to double

someHandler(4) -- Fails here if someHandler is not global.

end DoFirstHander
