Much of the last 10 or 15 years I've been brought in as a hired gun to 'maintain' (read fix) existing code. I follow a standard procedure. First I strip all of the comments. Then I reformat the code. I do the first step because
. I make the second change purely for comfort. When I use one or the other of the various code for-matters, I match my own standard which increases the code's clarity at least for me. With these two tasks accomplished I have at least a chance to succeed!
