Sorry, wasn't me, but hopefully whoever did it will chime in.

I've seen some scripts that appear to use globals but I couldn't see
that is was really necessary. As you say, variables only seem to
persist while the script is running, although there is no problem
referring to the same variable in more than one <?rev ... ?> block.
I think for real persistent data, you need to store it either on the
server as a file, or on the user's computer as a cookie, depending on
the requirements. You have to remember that multiple people could be
accessing the web page at the same time, so the same data may not be
valid for all. Session variables are another possibility, but not one
I have explored yet.
