thanks, what happens if the if in the 'next' line isn't true.
(If that's a question, then it should be closed with a question mark, incidentally.)
I personally believe that as with any other C<if>, if the condition isn't true, then the statement, i.e. next is not executed. Then, as with (nearly) any other statement, (that it has a statement modifier doesn't change this) control is passed to the following one. Pretty ordinary stuff, as you can see.
(Apologies for replying so late.)
