Steve Castledine has a good post on using aliases in Notes development. I’ve used them for years, (since v3 days), and I think that they are very useful.
Using aliases has saved me many times, when a user has decided to rename a form or a view. If you are using aliases, it’s a simple thing to do. Just change the name of the form or the view, and leave the alias intact. As long as all of your code points to the alias name, then you can change the “real” name as often as you like.
