Help with setRegistry?

[Ken Ray]

Eric,

On the Mac, your app will get apple events (specifically the "odoc" event),
from which you can extract the file path (this is from Ben Rubenstein from
an old post last year - thanks, Ben!):

>           request appleEvent data
>           if the result = empty then
>              answer "OpenDoc AppleEvent!" & return \
>                 & "id =" && eID \
>                 & "sender =" && eSender \
>                 & "data =" && it
>           else
>              pass appleEvent
>           end if
>        else
>           pass appleEvent
>        end if
>     end appleEvent
