Proof step 4 from proof okarray-int-put-02 (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ okarray(r, int_type, st) ∧ i < st[r -- _length] .intval ∧ 0 ≤ i → is_integervalue(st[r -- i '])
Proof step 2:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 3:
⊦ ¬ okarray(r, int_type, st[r0 -- j ', val]) ∧ okarray(r, int_type, st) → ¬ is_integervalue(val)

Rule argument
