–> Why does Think C use this custom pragma to do the job, when a more useful alternative exists? <– I disagree that the THINK C #pragma once (I presume that's what you mean) is less useful. Indeed, it helps ensure that you don't accidentally include a file more than once, thereby redefining stuff all over creation. It's automatic, too, unlike the more manual methods. FWIW, #pragma once is the same as #define _H_includefile, which is the same as the old #ifndef _H_includefile/#define _H_includefile/etc/#endif. You can even check for the existence of the preprocessor symbol _H_includefile. FWIW #2, Microsoft C (nit-pick: the product name isn't "Microsoft," even though I'm sure those arrogant b**t**ds enjoy having their name used as "the standard") does several things in a non-standard way, including merging the preprocessor symbol table with the compiler symbol table. This means you can #ifdef on a typedef name, for example. It's not necessarily AGAINST the standard, I suppose, but it's NOT something that's safe to depend upon. Joe
