Win32lib dialogs within proc's

I'm wondering if anyone has an elegant solution to this.  I'm writing a
windows program (actually porting a DOS program) using win32lib, and come to
a section in a routine where I need to get some input from the user by
opening up another dialog.  An example would be:

file = getOpenFileName(Main, "", {"All Files", "*.*"} )

But I'd like to get some information from one of _my_ dialogs.  I figure
that I could use a "callback" id, along with flags to let me know how far
into the original routine I got, and just have the window call the callback
when it's done, and add a bunch of 'if..then' statements looking at the
various flags I've set.

I don't want to do this yet, since I have about 60 or so routines, most of
which would need this type of overhaul.  Also, my future plands include
porting the routines into a script that would allow me more flexibility etc,
so I'll have to include into the scripting language any scheme that I come
up with.

Here's the basic format of what I have now:

procedure foo( atom a, atom b, )
atom target
while 1 do
        target = choose_target( a, "foo" )
        if target then
                ....do stuff...
        else
                ....do other stuff...
        end if

end while
end procedure

There may be other 'choose_target' (or equivalent) calls in the ....do
stuff...., which is why I think I'd need flags or something.

So, if anyone has any ideas, I'd _really_ love to hear them.

Thanks,
