Proof step 14 from proof okarray-put-badfield (previous step)

st[r -- _type] = typeval(ty1), ty1 = mkarraytype(ty0), st[r -- _length] = intval(i), 0 ≤ i, r -- _length ∈ st, is_arrayref(r, i, st), r -- _type ∈ st, is_typevalue(st[r -- _type]), ty0 ≤ ty, r ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ fs ' = _length, fs ' = _type, r = jvmref, okarray(r, ty, st[r -- fs ', val])

And obtained the following new goals

Proof step 13:
st[r -- _length] = intval(i), st[r -- _type] = typeval(mkarraytype(ty0)), r ∈ st, ty0 ≤ ty, r -- _type ∈ st, is_arrayref(r, i, st), r -- _length ∈ st, 0 ≤ i, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ r = jvmref, fs ' = _type, fs ' = _length, okarray(r, ty, st[r -- fs ', val])
