I just might quote that answer from now on, just to see how many >"huh?" answers I get back. ;-) LOL It will depend on the audience I guess. In CC circles like here "extension" is a reserved keyword, meaning searching beyond the nominal depth. Hence "minimum extension depth" might be confusing as extensions are considered not part of the nominal depth. But then again, some one asking a question usually prefers to get an answer, rather than a confusing note about why there isn't an answer. :-) ... Johan
