/**********************************************************************
HTML CALENDAR CONTROL
**********************************************************************
**
** Created By: Michael Barwell (based upon work by Patrick Milliken)
** Creation Date: 1/3/2002
**
** Purpose: The Calendar Control is a pop-up calendar that writes
** a user-selected date back to a specified text box on
** the calling form. The calling form opens a pop-up
** window, then this code dynamically writes the calendar
** HTML to the window.
**
** Modified By: Michael Barwell
** Altered to handle Australian (and European) date formats because all of the javascript
** date parameters are mm/dd/yy
** Last Mod Date: 1/3/2002
** 08/10/02 MB Altered for ADGP
**
