I've gotten in the habit of using the following format for conditional statements when I want the first condition to be ignored and the second to be acted on - if(such&such){ Nil; }else{ Do something } Is using "Nil" to represent "do nothing" a safe way to go? I've been searching around and I can't find any references to this. I've been doing it this way for a while and haven't encountered any issues, but I realize there's so many underlying rules with memory management and whatnot...I want to be sure I'm not developing any bad habits Title Comments I've gotten in the habit of using the following format for conditional statements when I want the first condition to be ignored and the second to be acted on - if(such&such){ Nil; }else{ Do something } Is using "Nil" to represent "do nothing" a safe way to go?

So using the 'not' operator (!) in your if statement would be the way to go. if(!(statement)){ do something } Comments Your basically just taking the inverse of the if statement.

Is that Buzztouch's first political joke in the forums?
