LIB$GET_VM_64 will only allocate the virtual memory and return the address
of the base of the region.  It should be just as simple to assign this to
your multi-dimensional array as it is to your single-dimension array.  It
is up to Fortran to index to the appropriate memory locations for each of
the elements in each of the array's dimensions.
