global problems

[xbury.cs at clearstream.com]

it's not different. The global is persistent until you delete it.

So if you delete your global and rerun your script (as you would recompile 
in other langs), 
the global wont show up again.

I thought i had demonstrated that with my script in the little mail 
following the question yesterday...
