I wonder how much memory we are talking about though? 100k? We are only talking about values like "LOOK_AT_THIS_COOL_DEFINE" and stuff like that. Maybe it comes down to how memory is assigned and it does save a bunch, but I'm thinking it's not really that much.

>>>I work on many different applications. I have a standard .H file where several of these reused constants are defined. As with the FoxPro.H file, I include the standard in the application once. Not only does it contains character to Constant definition, but also our company info, a few other constants that are used everywhere.

>>>>>>>Then look at this from a maintenance viewpoint. Values that appear in code are called, "magic numbers". They do something, but you don't necessarily know what they mean. It's just a number. And, it may appear in several places, which means if the value changes at some point, you have to hunt them all down. If you use a #DEFINE, you can give the number some meaningful name. And, if all the #DEFINEs are in a single file, you only have to go one place to change them.
