In your article you say: It also helpful to call SYS(1104) after code that process large tables to clear VFP memory cache and buffers.

My routine runs many Select-SQL lines, usually processing large tables. I am wondering how to go about implementing this suggestion.

The help file (for VFP9) warns: The use of SYS(1104) will slow performance in applications that have a large number of buffered tables open.

I guess that instead of calling SYS(1104) after each Select-SQL line that deals with large tables, it may be better to call it occasionally through the code.
