Why need reindex the table again?! Got problem!?
If really need so, do it before Quit!

Don't make fool update if you only modify one or two record(s)!!
If so, even you can use:

Select BadTable
Sort to GoodTable ;
on FieldKey1 /A, FieldKey2 /D ;
For .t.

USE in GoodTable

Set Exclusive On
USE in BadTable
Zap in BadTable
Set Exclusive OFF

Select BadTable
Append from GoodTable


But of cos, done it as you have got the Exclusive Right!
else you can't reindex, too!! +_+'
