If you just want the largest value (and its position) then
it can be done conveniently without sorting or grading.
If you want the largest k values where k>1 then
the most convenient way is to grade, along the lines
that Raul Miller has shown.

Why do you want to avoid sorting/grading?  In J, for vectors
of many datatypes, including the integer and floating point
datatypes, sorting and grading takes linear time.
