[Newbies] Pool Variables
Just curious, can someone give me an real life example of when you would need to use pool variables and no other variable would work?

RE: [Newbies] Pool Variables
Hi John, You might want to parse a configuration file but you are not sure where it is used. You could share these values using pool variables. It actually is useful but you can certainly accomplish this may other ways.

Generally information from external world are made available through pool variables since they are broadly consumed by many classes. Examples are * Physical or Math constants like pi, e, ... * Conventional names for weeks, months, colors, directions, playing cards, chess pieces. * Elements of binary file headers * Character and Font tables * Sensor events coming from hardware devices (like button codes) Explore SharedPool subclasses to see real-life usage in method source codes.
