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! -- Cheers -- Tim
