 * Function ...... Parse()
 * Purpose ....... To parse out tokens from a string
 * Parameters .... cString      String to parse
 *                 nIndex       Token number to return
 *                 cChar        Token separator
 * Returns ....... Token <nIndex> extracted from <cString>
 * Notes ......... If <nIndex> is greater than the number of tokens in
 *                 <cString> then a null string is returned.
 *               . Uses function Left, Right, and ParseCount
