Ahhh. Ok. I've got you... I was under the impression it was where they are 'first used'.
i.e. if a function is not called in the main code until after the declaration of a variable (outside of the function) then it was 'first used' in the main code and hence global... I guess 'first used' means 'first parsed'... --- In amibroker@yahoogroups.com, "Mike" <sfclimb...@...> wrote: > > Your assumption is mistaken.
