If you have a concern about two users running this code at exactly the same instant (theoretically getting the same value for SECONDS()), then you could substitute 'XX' with something like the user's login code or workstation ID in order to guarantee uniqueness.

Oops...last couple of lines should read:

USE IN WhateverMyAliasIs
DELETE FILE (m.lcTempDBF)
DELETE FILE (m.lcTempCDX)
