I tend to put my return value in a variable and at the end of the function I have 1 return statement. I have seen others doing returns in the middle of the function. -snip- What is your take? And is there any benefit to either method? Peter van der DoesPeter: It's called "Structured programming" -- one way in and one way out of a function. There are, of course, exceptions where it might help others reviewing your code to see what's going on, such as returning a null value if the argument(s) provided are not suitable. But normally the rule is, do not provide an exit from a function in more than one place. The "benefit" is easier to read code.
