Subject:      [CS3304_1381] Returning from a function/proc

Is it possible to return from a Pascal function other than by getting to
the end of it?

IE, in C++, if you want to get out of dodge if your input is invalid,
you do something like this:

void SomeFunc(CSomeType* pBlah)
{
        if (NULL == pBlah)
                return;

        if (!pBlah->WhateverIsValid())
                return;

        // Other processing here
}

Is there a way to do this other than having a nested if/then/else for
every way you could want to leave a function?

-David
