Scope of Variables
Symbolic variables defined in Variable Blocks are global to the object in which they are
defined but not outside of that object. This means that these variables can be accessed
directly from anywhere within the object but their name will not conflict with symbols
defined in other parent or child objects.
Public and Private methods have the ability to declare their own local variables. See
page 287, and
Global variables are not accessible outside of an object unless the address of that variable is
passed into, or back to, another object through a method call.
