Globals, write once run everywhere, whats wrong with that?

Trouble with programmers is that they define on the fly with no sensual objective of what huge bucket of crap they are not documenting. Engineers write small modular pieces and generally understand what machine code is and which way the solder drips. Pogrommers are rapid typists writing the great american novel and are surprised when the 2 record database they tested on doesnt behave the way the 200 kajillion records in the production environment.
All present company excepted of course and a couple of my buds.

There globals and there are Globals.

That is, there globals that stick around for the life of the application and then there are "global" variables within a module with a short lifespan. CGI and web script programming is like that: it's easy to use "global" variables in PHP, but they die when the page is finished. So they only have a short lifespan, unlike global variables in more traditional languages (like C). PHP's equivalent is called session variables, but you have to make a special call to convert a global variable into a session variable. This encourages some discipline.

Despite it's other flaws, Visual BASIC was like this. Truly global variables required additional declarations, as did mere module-wide variables. Unfortunately, there was a compile-time option to disable this requirement.

Myself, I dislike long-lived, volitale global variables. If I find myself about to use them, I tend to stop and try to fix whatever's broken to require them. Not always possible, note, but I try.
