[abc123]

Yeah, thats the way I used to like to do it but I found that the other way is pretty useful instead of putting huge if/else's around your code, saved me heaps of time and confusing

if(cantContinue) error("whatever"); return;

rather than

if(!cantContinue)
{
  //do things
}
else
{
  //stop
  error("whatever");
}
