> I was unable to create a Readwrite cursor- Is it because I'm using VFP 6?

Yes, the READWRITE modifier was introduced in VFP7. It is a great help - in earlier versions we had to jump through a quite few hoops to achieve a similar effect.

The easiest workaround for VFP6 is to re-use the temporary DBF underlying the cursor in a different work area:

use dbf([QueryResult]) shared again alias UpdatableAlias in select([UpdatableAlias])

but in that case it is vitally important to add the NOFILTER modifier to the original SELECT statement.

If the NOFILTER is missing then Fox could give you a filtered view of the original data instead of creating a temporary DBF. The danger is only with certain types of queries but it is a good idea to add NOFILTER whenever you intend to modify the result cursor.
