I'm not sure whether there's a significant difference in memory usage, but IMO the difference in scoping rules is a significant consideration. Constants carry over into functions local scope, while variables must be explicitely passed or declared as global in order to become available in a function's local scope. Which one you consider to be the "convenience" and which you consider the "nuisance" is in the eye of the beholder <g>, but IMO either way it's a very handy/exploitable distinction which you can use to speed up development/debugging time. -- CC
