Do constants take up much space?

Evening gang, I'm in the throes of writing myself an error handling class. One of the things I always did very early on in my C/C++ projects was to create this module, and additionally I'd create an enum typedef{}to aid readability of my code, so that I was always in every function returns e_OK instead of TRUE. In our dear PHP I'm using define() to create my e_OK variable, too easy. However the list of my error definitions can swell to about 20 or 30 (does that say something about my code *snicker*). What I wondering is the following, Let say I end up going mad (hey it happens in our industry) and create around 300+ error codes, what penalty am I going to incur in my scripting? Any? Do they take long to define? Cheers guys. -------------------------------------------------------------------------- Matthew M.
