RE indexes

[Richard Kreiss]

Interesting problem:

A client was running an output and towards the end of the output run got the
following:


*** A filePro Error Has Occurred ***

Fatal error

On File: F:/filepro/l_doctor/index.B

Invalid index.
Run Index Maintenance to rebuild the index.

This is a single field index on a 4 character numeric field.

When I enter the file and use index B to get to a record, no problem.

When I go to another file which does a lookup to this file using index B no
error - this is in clerk.

Why would a lookup in *clerk not encounter  the same index problem as
*report?
