Hi Nancy,

>Since, I have the luxury of being--to date-- all xBase, I wonder what one can do for optimization against non-xBase backends? Or would one concentrate more on using FetchSize (?)?.

I've no idea, I don't do data. *g*

What I meant is that SELECT issued against a local table and LIST FOR (or any other xBase command) issued against a local table use different optimization engines. For example, NOT == is optimizable in xBase, but not in a SELECT statement, functions are treated differently, and with SELECT, SET ANSI comes into play...
