I can't help you for SGI equipment, but the dbx for SPARCstations
provided in SPARCworks 2.0.1 appears to do exactly what you want.

The manual *Debugging a Program* states

Syntax for FORTRAN Array Slicing and Striding

     For each dimension of an array, the full syntax to the
     print command to slice the array is:

	 (debugger) print arr (exp1:exp2:exp3)

	 where:

	     exp1 = start_of_slice
	     exp2 = end_of_slice
	     exp3 = length_of_stride
		    (the number of elements skipped is exp3 - 1)

    For an n-dimensional slice, separate the definition of each
    slice with a comma:

	(debugger) print arr (exp1:exp2:exp3, exp1:exp2:exp3,...)

The manual goes on to explain how the elements are laid out in storage,
and convenient shorthand notations.
