> What would be the difference between adding and deleting an element?
Because you might be writing to an element that doesn't exist. Some versions/settings, 4D crashes. Other times, it doesn't crash but your array isn't right. If you've got a group of arrays working together to implement some kind of data structure, you might end up with 'rows' where the various columns are about a mixture of different things because of bad luck with timing. So, you're risking crashing, having bad data, or having meaningless data. And, again, all very hard to detect and correct after the fact. ********************************************************************** 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:4d_tech-unsubscr...@lists.4d.com **********************************************************************
