Can a constant be global?

As far as I know, constants are only valid in the current script.
Globals are really "Global" but then they can't be initialized to a
value when they are defined, which is why I assume constants can't be
The only way I have found to make constants "Global" is to make and
use a Library Stack that becomes a sort of poor man's constant.
Here's what I do:
ConstantLib - In the stack script
constant kConstant1 = "XXXXX"
constant kConstant2 = "12"
Then do a "start using ConstantLib" somewhere in the stack(s) that
you want to "see" the constants and when you want to access one do this:
put kConstant1() into myValue
add kConstant2() to myNumber
Hope this Helps
All the Best
