you have Local and global but for global you dont need to type anything extra
i.e.
--script 1
local var = 1
--script 2
local var = 2
depending on which script you ask the value will change and any other script wont be able to find 'var' at all.
but if you use
--script 1
var = 1
--script 2
then from all scripts 'var' will always be 1 unless you change it in another script (var = 2 etc)
