Hi all,

The VFP 5.0 Developer's Guide states at page 396, parag. 5, " Avoid using indexes on fields that contain only a few discrete values such as a logical field"

So then why should having an index based on deleted() be considered indexing effectively using Rushmore (see DG page 400)

Aren't these two very similar in their respective context (i.e.: few discrete values .T. or .F.).

Why should it be OK for deleted() and not for the other(s)?

Thanks

Pierre Richard
