  Dear rooters,
  I know that for one dimensionned array of basic type defined in a class,
in order that the values may be written to file, the way to define the array
is:

  Int_t  fN;   //dimension of the array
  Int_t *fP;  //[fN] one dimensionnal array

  How to proceed for 2 dimensionnal arrays **fP ?

  Thanks a lot in advance.
