If it doesn't, I put it on a line by itself, so it doesn't get lost. It's probably not entirely consistent, but it works well for me. Note that I also dropped some extraneous parentheses. Too many parentheses can be as confusing as too few, and I think it's sufficiently obvious that "==" and "!=" bind more tightly than "&&". The alignment of the subexpressions helps. I do not suggest that my style is the only correct one. -- Keith Thompson (The_Other_Keith) kst-u(a)mib.org <http://www.ghoti.net/~kst> Nokia "We must do something. This is something.

(Some people will realise that threse are different ways of saying the same thing).

Use a bigger screen! I'm sure the developers of Eclipse and NetBeans must all use 30" panels... -- Ian Collins

Actually, 99% of my editing is done remotely, so I use plain text editors, because they let me do important things, like preserve an editor session while travelling, or through several reboots, and so on. Even when I'm working locally, I edit in a text editor in a shell, usually. I find the convenience of the tools and environments and the faster interface to be a win. -s -- Copyright 2010, all wrongs reversed.
