| Well, I later tried it.  I populated a Field in the records where
| dt(10,mdyy/) = "12/31/9999" and Field = dt - Invoice_Date.  I then
| built an index with the primary sort on Invoice_Number and the
| secondary sort on that Field.

The primary sort key was the Customer Account Number and the secondary
sort key was the field holding the value of Number of Days from the
Invoice Date to 12/31/9999.

BTW, my program to create a filePro User Menu to enable quick changes
between versions of filePro came in quite handy.

| In a Browse Lookup, using that index, they still show up in order
| of their dates - not in reverse order of them.
| 
| I built a demand index on them, and using it they show up in the
| order I would have expected using that automatic index (no, I did
| not use a descending index in the demand index).
| 
| The eventual solution to the problem was to use "FILL=bot" instead
| of "FILL=top" in the browse lookup (sorting on Invoice # and date).
| 
| BTW, I didn't write this table in the first place, and its author
| used "fill=asc,top".  It's worked this way since 1991 or 1992 with
| no complaint.  I don't understand the "asc" he used ? ? ?
