 ROTARY: Simulates Turning a Knob

 The ROTARY sample application simulates turning a custom 
 knob control. To use ROTARY, click the mouse directly on 
 or near the knob. With each click, the knob "turns" and
 its value increases or decreases, as indicated in units
 below the knob.

 ROTARY was built and tested under Microsoft(R) Windows(TM) 
 version 3.1.
