Proof step 3 from proof isarray-02 (previous step)

∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → r -- j0 ' ∈ st[r0 -- j ', val], i ≤ j ⊦ ∀ j. 0 ≤ j ∧ j < i → r -- j ' ∈ st

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
j0 < j, 0 < i, 0 ≤ j0, i ≤ j, j0 < i, 0 < j, ∀ j0. ¬ j0 < 0 ∧ ¬ i ≤ j0 → r -- j0 ' ∈ st[r0 -- j ', val] ⊦ r -- j0 ' ∈ st
