I believe WB maintains a list of locks. When it gets a DISKCHANGE it unlocks
them and tries again. If you have an open lock, of course, it gets the
same disk from the device list.

I don't believe that any other program can do this, because you'd never
have workbench and your program releasing its lock list at the same time.
For Browser, I just gave up and go by the volume name. If you're replacing
Workbench completely, you can of course do it the way they do it.

Sigh.

Good question. I'd like to know this too.

Ditto.

William LeFevbre at (phil@rice.edu) did a display-only 'info' program for
Browser. You might want to ask him.
