string getProjectedCoordinates(string x, string y)

This method takes input coordinates (x, y) in the Exchange Coordinate System and transforms them to projected coordinates in the map's coordinate system.  

This method should not be used unless the map's coordinate system is of type NEMR (See Map Types).  One of two possible transformation types is performed: geodetic to projected,  or projected to projected, depending on whether the Exchange Coordinate System is geodetic or projected, respectively.

The returned string is a comma-separated pair of alphanumeric decimals (x, y).
