Re: [Genparse-users] Multiple global functions?

[Mike B. <mi...@bo...>]

I don't think there was any rationale for the single global callback 
function except that it kept things simple at first.  Now that the 
program is much more sophisticated, I think that multiple callbacks 
would be fine.

The #exit directive seems useful as well.

Thanks,
Mike
