Proof step 43 from proof fits-put (previous step)

st[r1 -- i '] = refval(r0), i < st[r1 -- _length] .intval, okarray(r1, byte_type, st), r1 ∈ st, 0 ≤ i, 0 < st[r1 -- _length] .intval ⊦ r1 = jvmref, junkref(str, r1, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 38:
⊦ okarray(r, ty, st) ↔ okreftype(refval(r), mkarraytype(ty), st) ∧ r ≠ jvmref ∧ r -- _length ∈ st ∧ is_integervalue(st[r -- _length]) ∧ 0 ≤ st[r -- _length] .intval ∧ is_arrayref(r, st[r -- _length] .intval, st) ∧ (∀ j. 0 ≤ j ∧ j < st[r -- _length] .intval → oktype(st[r -- j '], ty, st))
Proof step 42:
st[r1 -- i '] = refval(r0), i < st[r1 -- _length] .intval, okreftype(refval(r1), mkarraytype(byte_type), st) ∧ r1 ≠ jvmref ∧ r1 -- _length ∈ st ∧ is_integervalue(st[r1 -- _length]) ∧ 0 ≤ st[r1 -- _length] .intval ∧ is_arrayref(r1, st[r1 -- _length] .intval, st) ∧ (∀ j. 0 ≤ j ∧ j < st[r1 -- _length] .intval → oktype(st[r1 -- j '], byte_type, st)), r1 ∈ st, 0 ≤ i, 0 < st[r1 -- _length] .intval ⊦ r1 = jvmref, junkref(str, r1, st)
