     About a week ago I sent out a request asking if anyone knew how to find 
out from which drive a Basic program had been executed.  I got two responses.
The first indicated that location $301 (or PEEK(769)) returns the unit number
of the last SIO call, which will be the loading of your Basic program if you
do nothing else in between.  The second, which was posted to the mailing list,
was an incredibly imaginative hack which involved moving the cursor back to 
the line containing the "RUN" command, scanning it for a colon, and looking for
the number immediately preceding it.  I liked that one; I may have it framed.
Unfortunately, it won't work from a chained program.  Still, an extra two 
points for the imagination required to come up with that one!

     Thanks to both respondants.  A happy hacking to all.
