>I have a table created by VFP 8.0 and also running on an application compliled by VFP 8.0 which being report corrupted and can not be used by VFP 8.0 application. I tried to open that table using VFP 5.0 and it works. Well I hope this information can be usefull to others.

This should allow you to open it in VFP8:
SET TABLEVALIDATE TO 0

Of course that's not really fixing the problem with the table..its just turning off the tablevalidtion.
The best way to fix the table is to add a new field, then remove it...something like this:

lcTableName = GETFILE('DBF','Select Table To Fix')
lcTableValidate = 'set tablevalidate to 0'
&lcTableValidate

use &lcTableName exclusive

alter table &lcTableName add column vvvxxxvv c(1)

alter table &lcTableName drop column vvvxxxvv
use

lcTableValidate = 'set tablevalidate to 3'
&lcTableValidate


....the reason for the macro substitution is so that it will still compile in the older version of VFP. (there is no 'tablevalidate' in the older versions...
