is there any real benefit to declaring a CONSTANT over just defining a variable?The fact they can't be overwritten makes them more appropriate for true constants, absolutely no way to change their values. I frequently use them in include files to set widths, etc., that are brought into all the pages in a project. Plus, they have global scope - great if you are in the habit of forgetting global declarations in functions <g>. And my guess is their is less overhead in using them, even in an interpreted environment.
