No it's not. What you get is only the last record. A locate command supports continue and found. This doesn't.
Well suggesting skip -1 would be overkilling. You might not know if intention is doing a scan while...endscan or alike.
An index is the way to go IMHO. If no index exists creating an index with a dummy key does well (IMHO every table should have such an index) :

index on .t. tag myLocator

set order to tag myLocator descending
