Show off! Just kidding, of course. Don't know when I'll ever get
around to using this feature, but once I've digested it, I feel
pretty sure that it's amazing qualities will hit me right between the
eyes!
Thanks, Jim,

Custom properties are very fast, powerful, and get saved with the
stack.
Variables, such as globals and script locals, evaporate, and are
not saved
with the stack. Custom properties have even more power when done
as custom
property 'sets'.
Think of custom properties as a table that can be stored inside an
object
(like a button, card, stack). The left column has the label ("
cpUserName
", " cpUndoValue ", " cpPrevRect ") and the right column has the
string that
is the value.
cpUserName "Paul"
cpUndoValue "Red"
cpPrevRect "34,56,788,675"
Now add the concept that you can have unlimited tables stored in a
single
button, card, stack by naming the tables
-----copy script lines -----------
on mousedoubleup
set the custompropertyset of this stack to "cpsPaulsData"
set the cpUserName of this stack to "Paul"
set the cpAge of this stack to "24"
set the custompropertyset of this stack to "cpsMarysData"
set the cpUserName of this stack to "Mary"
set the cpAge of this stack to "unknown"
save this stack --does not work for standalones
set the custompropertyset of this stack to "cpsPaulsData"
answer "the user is "& the cpUserName of this stack & \
" whose age is "& the cpAge of this stack
set the custompropertyset of this stack to "cpsMarysData"
answer "the user is "& the cpUserName of this stack & \
" whose age is "& the cpAge of this stack
end mousedoubleup
---------end copy script lines
As you might have guessed, I use "cp" for my custom properties, and
"cps"
for sets.
This is basically a flat file database that can be stored in any
and all
objects. Very powerful and it is instant access speed.
