// Modifications:
// --------------
// ami 05/26/2007 Original
// KJI 10/19/2007 New functions (changeImages & changeImagesArray) used for changing an image onmouseover. (see page1.asp & Order1TN.sap)
// KJI 10/31/2007 Put Order2Text.asp & Order2NonEnglishText.asp as an exception for cursor positioning so default cursor position is "NEXT" button not "Back".
// KJI 11/06/2007 In Function checkFLUCase took out numbers from "alphare" relational expression so numeric values would not be edited for lower case.
// KJI 12/26/2007 Don't position curson in first input field of Ring50Review.asp or Ring01Series.asp.
// Jay 08/20/2008 Changed truncCity function to allow 16 characters
// KJI 09/04/2008 Don't focus in first field (0,0) for Order1TN.asp or Order2.asp.
// KJI 02/27/2009 CheckForAssociate pass School. If "HES" don't check for Associate.
// KJI 07/17/2009 Changed bodyOnLoad() for Order3.asp.
// KJI 03/12/2010 New function - GetXmlHttpObject()
// Jay 07/29/2010 Don't focus on the first field on UpdateConfirm.asp
