The problem with global variables is their long range effect,

I like `goto' a lot, and it is an invaluable instruction if used with
care. The same is true with global variables. Sorry to say, but we
are now going into hearsay and hollow statements, which isn't helpful.
I may have to look into this C++ stuff. I have only written C and I have
not figured out how to write multi-threaded applications without global
variables. And I make good use of goto and longjmp. Apps would be a lot
junkier without them.
