>I always though I was able to create a SQL cursor (read-only) based on previously created SQL cursor (read-only) but I guess not. I get an error something like "Must SELECT...INTO TABLE" on the second attempt. Thus, I have to do USE DBF("cursor") AGAIN... before the second SQL-SELECT statement. Any reason why?

You can select on cursor from another. I've seen this erro before but I don't remember the circumstance. What does the select(s) look like?
