I have an FB II application that stores its preferences in a file 
that it finds using the following code:

   PrefVol = SYSTEM(_aplVol)
   PrefFile$ = "MovieTools Prefs"
   OPEN "I",1,PrefFile$,,PrefVol

This works fine under OS 9 and earlier, but doesn't work under OS X/Classic.

I'm still stuck in the stone age, and don't presently have access to 
an OS X machine for testing.  Can anyone offer a suggestion on how to 
make this work under OS X/Classic?

Thanks,

Lon McQuillin
