Sure, I know that, and it even makes sense. That's not my issue at this point. What bugs me now about all this is that a C source file contains two sections: One in which variable declarations and program statements are valid, and one in which variable declarations (and assignments) are valid, but where scalar quantities must be resolved at compile time. I realize that in practice, variables may be declared out of function scope, and that the language must offer a facility to initialize them to a known value (for practical reasons). But when you're looking at the code in an editor the only thing distinguishing these two "zones" is the presence of an open/close brace pair from a function call. It seems arbitrary, and I guess there's lots of reasons why it was done this way -- which I won't speculate about here to avoid flames. I suppose the real thing here to note is that languages like Perl or Python are insulated from the processor architecture to a much greater degree than C, and so some things are easier/harder than others in these languages from the programmer standpoint. I'm not going to switch to C++, so for my purposes, I'll be implementing some other solution. Possibly, I many end up without any global variables at all.
