----------------------------Original message---------------------------- The phrase "reinventing the wheel" has had its day and is now something which should not be used. In this age of data bases, we rarely reinvent anything so basic as the wheels, we are more likely - to keep with the analogy - reinventing - or at least redesigning - the wagon. This is a trivial point, I admit, but to say we reinvent the wheel is really misleading. J. B. Post
