// Project:      LA CITY PLANNING ZIMAS IMS
// Version:      Release 1.0
//
// File:         vars.js
// Language:     JavaScript 1.2
// Created:      2002
// Author:       Created: James Richards, LA DCP; Modified: Daniel Elroi, LA DCP
// Description:  Contains all of the global level variable definitions for ZIMAS.
//               Conventions for the definitions of these variables include:
//               - "constants", which are ALL_CAPS by convention.  Even though
//               JavaScript does not have a Const keyword, values that should
//               be constants are stored in variables with ALL_CAPS.  You
//               should never change the contents of a constant once it is
//               defined in this script.
//               - "member" level variables, which should follow the naming
//               convention "m_<type>VariableName", where type is a one
//               (or few) letter code specifying the type.  Even though
//               there is no strict typing of variable in JavaScript, it
//               is a good idea to name variables in this way for readability.
//               Examples: 
//                 m_bBalloonHelp - boolean indicating on/off state of help 
//                 m_sMessage - string to hold a message
//                 m_dMaxX - double to hold the maximum x value
//                 m_arCommands - array containing several elements
//               - Browser sniffing object: this file also contains the client
//               side script for sniffing and determining the hosting browser.
// Dependencies: aimsXML.js, ArcIMSparam.js, aimsCommon.js, aimsMap.js,
//               aimsLayers.js, aimsDHTML.js, aimsClick.js
// Issues:       Contains two sections (12/5/02) - "A" from the "old" ZIMAS and
//               "B" from the ArcIMS 4.0 HTML Viewer (source ArcIMSparam.js, 
//               aimsMap.js, and aimsXML.js)
