Proof step 7 from proof getintarray-subset (previous step)

r ∈ st, r -- _length ∈ st, st ⊆ st0, j < st0[r -- _length] .intval, 0 ≤ j, 0 < st0[r -- _length] .intval, ∀ j. ¬ j < 0 ∧ ¬ st0[r -- _length] .intval ≤ j → r -- j ' ∈ st ⊦ getintarray(r, 0, st0[r -- _length] .intval, st) = getintarray(r, 0, st0[r -- _length] .intval, st0), r -- j ' ∈ st
