   @Angle(GEOM, <source type>, <dest type>, [,<optional attr list>])
   @Angle(ATTRIBUTES, <source type>, <dest type>, [,<optional attr list>])
   
Arguments

   <source type> 
      The format of the input angles.
      
      Range: DECIMAL_DEGREES, DDDMMSS.SSO, DDDMMSSSS, DDDMMSS, RADIANS
   
   <dest type> 
      The format of the output angles after conversion.
      
      Range: DECIMAL_DEGREES, DDDMMSSSS, DDDMMSS, RADIANS
      
   <optional attr list>
      The list of attributes containing angles that are to be converted.
      If GEOM is specified and this list is empty then only the 
      coordinates will be converted from <source type> to <dest type>.
      
      Range: attributes
   
Description

   The conversion type is one of the following
   
   DECIMAL_DEGREES   - decimal degrees (e.g.  23.4567)
   DDDMMSS.SSO - degrees minutes seconds orientation (e.g. 274531.01N)
                    27 degrees 45 minutes 31.01 seconds North 
                    NOTE: This is not available as a destination type
   DDDMMSSSS - degrees minutes hundredths of seconds (e.g. 78341034)
                  78 degrees, 34 minutes, 10.34 seconds.
   DDDMMSS   - degrees minutes seconds.                  
   RADIANS   - radians. (e.g. 1.456)

   If GEOM is specified then the function converts the geometry coordinates from the 
   <source type> representation to the <dest type> representation.  If any attributes
   are specified in the <optional attr list> then the value of those attributes is also
   converted from the <source> to the <destination>. 
   
   If ATTRIBUTES is specified then only the attribute(s) in the optional attribute list
   is converted from <source type> to <destination type>
