Proof step 9 from proof okbar-put-01 (conclusion)

⊦ okbytearray(r, st) ∧ okbytearray(r0, st) ∧ 0 ≤ j ∧ j < st[r0 -- _length] .intval → okbytearray(r, st[r -- i ', st[r0 -- j ']])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
okbytearray(r, st), okbytearray(r0, st), j < st[r0 -- _length] .intval, 0 ≤ j, 0 < st[r0 -- _length] .intval ⊦ okbytearray(r, st[r -- i ', st[r0 -- j ']])
