This point isn't actually blindingly obvious. Those of us raised on Pascal might have assumed (or, in my case, actually did assume, without thinking hard about it) that the program ended when the execution point reached "the end," where the main method was probably located in the binary. It's disturbing how many Pascal-isms still pervade my thinking, even 20 years since I last (willingly) touched the language.
