There are other scripting languages that use the JVM. They are better for this sort of thing than Java with its verbose strong typing. see http://mindprod.com/jgloss/scripting.html -- Roedy Green Canadian Mind Products http://mindprod.com If you tell a computer the same fact in more than one place, unless you have an automated mechanism to ensure they stay in sync, the versions of the fact will eventually get out of sync.
