Ah, a terminology dispute. Fair enough. So how would you define
"global variable"?

To me, a global variable is one that's not local, where local
could be local to a procedure, function, object, module, block,
or (almost) anything else.

Whereas to me, a global variable is one that's accessible from
everywhere, without your having to do anything special to make it
accessible from a particular place. As in VS/BASIC, for example.

The only BASIC variants I've used extensively didn't support
modules in any form or shape, so I don't know enough to comment on
Microsoft's latest.

Neither do I. I was thinking of the BASICs of our youth.

Ah. I figured you meant Visual Studio's BASIC. I had searched for "VS/
BASIC" but couldn't find anything relevant, because of the many, many
unrelated results.

VS/BASIC shipped with VM/CMS about a trillion years ago. (It may still
do so, for all I know.) It was my first programming language, closely
followed by EXEC, which was a weird kind of batch/scripting language,
sortakinda.

Incidentally, the reason for my "no special syntax" rule is that
otherwise we'd have to count, say, fields in a database as global
variables.

I'm not sure I would count them as variables, global or otherwise.

And I'm not sure that I would count 'variable' as being a useful C term.
(I accept, however, that the Standard does mentions them from time to
time.)
