>This is probably a stupid question, but here it goes. I need to know if there is a way to detect the existence of an array in Foxpro 2.6. I am creating an array with a SELECT - SQL statement, but if this results in 0 items the array isn't created. This causes problems later in the app. Is there a way to check its existence without trapping the error it could generate later? Thanks for your help in advance.

You could check IF _TALLY=0 immediately after SELECT-SQL.
