Purge and global variables

[Graham Samuel]

As part of a test about preOpenStack messages, I have a global 
variable which I increment by 1 every time the Revolution sends 
preOpenStack to my mainstack. I was surprised to find that the 
incremented value survived the destruction of the stack using the 
"Purge" button in the Application Overview palette. I mean, it got 
set to '1' when I first ran the code, but when I purged the whole 
file and reopened it, the global came up as '2'. I'm up to '5' now... 
Maybe it's something to do with the presence of the Revo Development 
Environment (haven't tried it with a standalone).

Is there any official word on what is supposed to happen to globals? 
I kind of assumed that at the first declaration, a global would be 
empty.
