Then you're probably using it way too often.
Global scope variable are inherently dangerous and cause more problems than
they're worth. I've been in this business well nigh 30 years now and have
had more problems with globals than I can shake a stick at. Passing
parameters ain't a bad thing, you know, even when what you're passing is a
variable declared in global scope (like variables set via post or get).
Global is inelegant by definition ...
I worked in Fortran 77 for 10 of those years; we were really careful with
common blocks and included them only where absolutely necessary. Passing
array blocks was in almost all cases a "better thing" and was not any
slower.
