Subject:  HyperCard Instance Variables

Equipment:  Macintosh

Summary: Objects in HyperCard are not allowed to have variables inside 
themÑuntil now.  Instance variables are useful for storing more data with 
a button or field.  This stack script allows you to have variables 
attached to a button, shared field, or other HyperCard object.

An object may have any number of variables. Values are preserved when you 
quit.  They stay with your stack when you drag it to another disk.  The 
objects that can have variables are: a card button, a card field, the 
card itself, a background button, a shared field, or the background 
itself. 

Requires: HyperCard 2.1 or later

Keywords: HyperCard, variable, button, field, instance variables, global, 
saving state
