Coding would come up a lot. I have to say, John and I tended to disagree about pretty much everything, top to bottom. And, for what it's worth, I can't think of a person I've met who more easily took up new tools and languages and managed to come up with novel solutions that were good for his customers. He's also taken over Flex and 4D projects I started, so he knows where I've buried the bodies ;-) Anyone that enjoyed John's popular "Tips & Tricks" presentations years back at the Summit should remember that John is, above all, pragmatic, not dogmatic. So, I know perfectly well that when I tell John he's "wrong", he'll ignore me ;-) The evils of globals come up faster when you have messy code and/or multiple coders. Same with bad parameter passing, etc. You can put up a ton of scaffolding to trap and handle coding mistakes. Or you can just not make mistakes and strip out all of the guardrails. ********************************************************************** 4D Internet Users Group (4D iNUG) FAQ: http://lists.4d.com/faqnug.html Archive: http://lists.4d.com/archives.html Options: http://lists.4d.com/mailman/options/4d_tech Unsub: mailto:[email protected] **********************************************************************
