I actually try to avoid imagining what you do over there, Tom. ;

I also work on somewhat large pages with somewhat large amounts of data and
quite large code libraries. On some of these pages, I use global variables.
I do not consider them evil, personally. When used appropriately, they can
be quite effective--I find that they save me time coding and they do
precisely what I need them to--hold global bits of information.

I think that if a datum IS indeed global, then it probably BELONGS in a
global variable. I await, however, the dissenting opinions. :)
