That's exactly right. There's been quite a bit of discussion of
globals here over the last couple of years. Basically declaring a
variable as "global" flags it as a candidate for being used in other
scripts. Then declaring the variable a global in a second script
references the first instance of the variable. The whole thing is a
bit error-prone, if you ask me. I avoid globals whenever I can, but
sometimes you gotta use them.
