Thanks!

>The order is listed in the FUNCTION Command (http://msdn.microsoft.com/en-us/library/10cc6ya9%28VS.80%29.aspx) and PROCEDURE Command help topics under the remarks section:

When you issue the DO command with a function name, Visual FoxPro searches for the function in the following order:
>1.    The file containing the DO command.
>2.    Procedure files opened with SET PROCEDURE.
>    For more information, see SET PROCEDURE Command.
>3.    Program files in the execution chain.
>    Visual FoxPro searches program files in order from the most recently executed program to the first program executed.
>4.    A standalone program file.
>
>If a matching program file is found, Visual FoxPro executes the program. Otherwise, Visual FoxPro generates an error message.
>
>To execute a function in a specific file, include the IN clause in the DO command.
