abs() looks like a function but in fact it isn't. So it's a very special kind of "function" (at least it is similar to a set of overloaded function or a kind of "generic"). In Pascal same is true for typecasts. C is more straight forward: typecasts don't look like a function so you are not astonished to see that they don't perform any action. abs() does not exist in C (you can of course do a simple #define macro for that). -Michael ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
