A Fortran 90 pointer type points to scalar or array types.

NextGen TotalView for HPC implicitly handles slicing operations that set up a pointer or assumed shape subroutine argument so that the indices and values it displays in a VAR drawer and Data View are the same as in the code. For example, this code sets up and assigns an array and a pointer to that array:

Figure 63displays the original array ia21 and its pointer ip21 in the Data View.

Figure 64illustrates the pointer ip21 representing a slice of the ia21 array after the assignment of the pointer.
