Hi,
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
"Global".
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"
function kConstant1
return kConstant1
end kConstant1
function kConstant2
return kConstant2
end kConstant2
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
or
add kConstant2() to myNumber
or
get kConstant1
Hope this Helps
All the Best
Dave

This is another of those things that I've lived without for years -
I normally use globals to contain text strings which may change if
the human language of the app changes (what is the Welsh for
"Cancel"? - don't know, but I know someone who can tell me!), so
that all the values can be initialised in one handler when the app
starts up: but after all this time I thought I'd try using
constants instead.
However neither the RR documentation nor my experiments seem to
suggest that there is a way of making constants global (i.e
constant). Can this really be true? If so, they have a crushing
disadvantage with respect to globals. After all, RR's own constants
are global. I guess I've missed something.
Thanks to anyone who can dispel another of my clouds of ignorance.
