Something like if (word==true) { ... } when the variable word is itself a boolean is redundant - you can just write if (word) { ... }

Edit: Ignore me if you were questioning the statement "don't use...", didn't take your meaning first at first read

I do agree there is alot wrong with this code. But what do you mean with "don't use the boolean property of the parameter"?

VERY slow? How is this very slow?
