Double salvo function

red_moon

I just read a function code like this : :laugh:

function MightyFunction(paramA, paramB, paramC)
! Lots of code here.
! But this is the magic.
Return retA
Return retB

The code is written in Centura 1.5, and the compiler compiled it successfully.

It's easy to laugh, but, it's so hard to smile ...

That would compile in Visual Studio also. Just a warning about "unreachable code detected".

I sometimes use kick-out returns to temporarily 'comment out' code I suspect of breaking things. You can still do it in C# (might be an error in Java, I forget), and obviously in things like JavaScript or PHP. Leaving one in is pretty bad though.

I just can't imagine, what the intention of "double return" :-D

It's easy to laugh, but, it's so hard to smile ...

Hmm, for some reason that reminds me of the custom scripting language used in the game "Space Empires V"... one of its unique quirks was that a "return" statement did not actually terminate function execution! So the function you describe would in SE5 script wind up returning retB, because it's the last return statement to execute...

Julien Villers

Pascal also has a non terminating return semantics, but it's much clearer than that (as could be expected from Pascal ;))!

Hmm, that would actually explain the SE5 language, as it does look quite a bit like Pascal... the guy who wrote the game was apparently primarily a Delphi programmer!
