FAQ321B.txt   Unsupported Expression Indexes
Category   :Database (FoxPro)
Platform    :Win95/NT
Product    :  

Question:
What types of FoxPro indexes are not supported by the BDE?  
When trying to open some tables, I get an "Invalid Index
Descriptor" error.

Answer:
This error occurs when the production index (.CDX) associated
the table has an index tag which has an expression which the BDE
cannot evaluate. The solution is to delete the tag using FoxPro
create an eqivalent index that the BDE can understand.

The following conditions are not supported by the BDE and will
cause "Invalid Index Descriptor" error.

DTOC(, 1) format not supported; Use DTOC().
ALLTRIM function not supported; Use LTRIM(RTRIM(Field)).
