Hi Radovan,
Since I need the TString contents in char* format in a member function
of the same class (in which then I use the char* as an argument for the
invokation of a member function of another class) the above construction
should not be needed according to standard C++.
So to me it seems we have some sort of CINT problem here.

Any idea Masa ????
