In previous versions of Visual FoxPro, it was necessary to include an extra constant or expression as a filter to create a cursor that could be used in subsequent queries. For example, adding a logical true as a filter expression created a query that could be used in subsequent queries:

As Jim says, if you omit NOFILTER, you may or may not create a separate cursor. I have had cases where the same sequence of SELECT commands worked well, and later didn't. So, to be safe, if you have a sequence of SELECT commands, always use NOFILTER on the first cursor.
