Proof step 23 from proof okarray-put-02 (previous step)

¬ refval((r0 -- j ') .ref) ≠ val, okarray(val, byte_type, i, st) ⊦ okarray(val, byte_type, i, st[r0 -- j ', byteval(by)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 2:
⊦ okarray(refval(r), ty, i, st) → st[r -- _length] .intval = i
Proof step 3:
⊦ okarray(refval(r), ty, i, st) → r ≠ jvmref
Proof step 22:
okarray(refval(r0), byte_type, st[r0 -- _length] .intval, st) ⊦ r0 = jvmref, okarray(refval(r0), byte_type, st[r0 -- _length] .intval, st[r0 -- j ', byteval(by)])

Rule argument
