Dollar sign in a while statement
I've just found this snippet..
It's also used again later on:
while ((s = this.val[COLOR="Red"][B]$[/B][/COLOR]reader.readLine()) != null)
And I'm wondering what the dollar sign up there does.
I've Googled this for a while but haven't found anything.. (Google doesn't search for the dollar sign and a literal "dollar sign" search turns up different thigns on the whole.
