Key Definitions for C02 Programs

This module contains symbolic representations of the character codes
generated by non-printing keyboard keys.

The set of symbolic names is intended to encompass all supported 6502
based microcomputers. Any key that is inapplicable to a particular
machine will have a defined character value of 0.

The default header file contains keys with standard ASCII definitions.

At the beginning of the program use the directive

  #include <key.h02>

The following are defined:

  struct keydef {};           Structure containing the symbolic key names
                        
  const struct keydef keys;   Struct variable containing the character codes

The structure contains the following members:

  key.bckspc      Backspace
  key.break       Break
  key.clear       Clear
  key.copy        Copy

  key.fn1         Function Key 1 
  key.fn2         Function Key 2 
  key.fn3         Function Key 3 
  key.fn4         Function Key 4 
  key.fn5         Function Key 5 
  key.fn6         Function Key 6 
  key.fn7         Function Key 7 
  key.fn8         Function Key 8 
  key.fn9         Function Key 9 
  key.fn10        Function Key 10
  key.fn11        Function Key 11
  key.fn12        Function Key 12

  key.right       Cursor Right
  key.return      Return
  key.shfrtn      Shift-Return
  key.run         Run 
  key.rvsoff      Reverse Off
  key.rvson       Reverse On
  key.shfspc      Shifted Space
