This is rather more difficult. To my knowlegde there are no standard 
methods for C++ call handling. So if your get this working by some trick
you may fail to make it work on any other machine. You could write a small C++
jacket which accepts opject A by reference and calls A.GetData() and call this
jacket from fortran: 
	 
      CALL GET_DATA_JACKET(OBJ, DATA)

However the C++ compiler mangles the names of routines. So your GET_DAT_JACKET
symbol would not be resolved unless you have a look at the map files for the 
true name (Something like GET_DATA_JACKETaB_12_876YFgDR... ) and use that name 
in fortran. Some compilers like GCC will let you define the true name by 
__asm__ directive. It is all very tricky and messy and not worth it at all.
