back in like '85, I learned Pascal that's the only language I learned and I
don't recall if it used return.
Mmmm. There's the problem. Pascal doesn't *have* a return statement. In Pascal,
implicitly, you return when execution reaches the end of a function. In fact
the same is true of PHP and JavaScript, but in those languages you can return
early just by saying return.
IMO, this is a major limitation of Pascal. I use returns wherever I feel like
it - if I detect there's nothing more for the function to do, I return. Purists
object to this; they say you should enter a function at one place and leave at
one place. Well, that's a point of view. But more often that not it just leads
to convoluted code in order to achieve that. The one time I *had* to use Pascal
as that was the only option, I simply put a 999: label at the end of the
function and did goto 999 wherever I wanted to do a return. Simples!
