That means not only that "use again" on a filtered cursor gives you a read/write cursor which is a filter on the original table, but that it actually behaves as an updateable view... which would be a nice shortcut, if we could rely on it. Since Fox decides when it will be a filtered cursor (unless we put NoFilter in select, we never know if it will be filtered or not), we can't.
