// PowerPC Calculator Processing Script
// Written by Dustin M. Waibel (x4750)
// Loosely based on original utility scripted written by Val Laolagi
// v1.0 (02/10/03): wrote functions.
// v1.1 (03/26/03): changed typeVirtexIIProDevice function to all if statements for
//                  better legibility.
// v2.0 (06/24/03): added the ability to clear drop-down boxes to InitForm; added the
//                  functionality to mulitply the drop-downs against the next occurring 
//                  radio button.
