\
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.\
\

\b Classes\

\b0 SimpleCalc -- A general class that directly supports a calculator interface.\
\

\b History\

\b0 Created 8-8-90\
Modified 9-10-90 -- User interface, added separate nibs for Info and Help panels.\
Modified 10-15-90 -- New alloc and init logic added.\
\

\b Notes\

\b0 Key equivalents are somewhat user hazardous -- equals on the keypad is clear in the calculator; enter on the keypad is equals on the calculator.\
\

\b Future Directions\

\b0 In class, students will add memory functions as well as printing.
