Database: Passing values between cards in a stack

[Ken Ray]

The simplest way is to use global variables, although custom properties
work well also. If it is simple data, sometimes I use "the dialogData" -
a predefined global data container normall intended for passing data
between a stack and a modal dialog box (but it can be used anywhere).

Example:

(button on card 1)
on mouseUp
  set the dialogData to "My Data Here"
  go card 2
end mouseUp

(script of card 2)
on preOpenCard
  put the dialogData into fld 1
  -- puts "My Data Here" into fld 1
end preOpenCard

So you see, you have a bunch of options...
