As Timebandit pointed out --

or SetGlobalVar in 1.0.x

If most of the interaction with that variable occurs through agi, you 
might also want to consider storing it outside of Asterisk.  I've stored 
a good number of values in mysql for an asterisk application before.  If 
most of the interaction occurs within the dialplan and/or you're trying 
to avoid agi, you could also use the asterisk database directly with 
DBPut and DBGet.
