In a program I take the contents of an ascii file, read it into a
.dbf and manipulate it, then present it to the user with
achoice(). Unfortunately, the ascii file contains dups, and I
dont want my picklist to have any. What is the best way to remove
them? Where is the best place - in the .dbf or in
the array. Ascan() and adel() dont seem to do the trick. I guess I
could try a locate/continue; Im wondering if anyone has a slick (but
maintainable!) idea.

On input, the ascii file might look like:
   4
   buffed.dbf
   trick.dbf
   stormin.dbf
   norman.dbf
I APPEND it into a database, delete the first line, pack the file, read
it into an array, then achoice() it.

Thanks in advance
