CalculatorLab
by Randy Nelson

A demonstration program that creates a simple framework for target/action and delegation/notification practice.

This is Lab One of the Developer's Camp.  The centerpiece is a somewhat general calculator object that uses the traditional rather than RPN interface.

Classes
SimpleCalc -- A general class that directly supports a calculator interface.

History
Created7&	-90
Modified 9-10-90 -- User interface, added separate nibs for Info and Help panels.
Modified 10-15-90 -- New alloc and init logic added.

Notes
Key equivalents are somewhat user hazardous -- equals on the keypad is clear in the calculator; enter on the keypad is equals on the calculator.

Future Directions
In class, students will add memory functions as well as printing.
