Proof step 18 from proof okarray-init-04 (previous step)

0 ≤ j ∧ j < n→i(# (vals + byteval(by) ')), 0 ≤ j, j < n→i(# vals), is_bytevalue((vals + byteval(by) ')[i→n(j)]) ⊦ r = jvmref, vals = [], is_bytevalue(vals[i→n(j)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 17:
j ≤ n→i(# vals), is_bytevalue((vals + byteval(by) ')[i→n(j)]), j < n→i(# vals), 0 ≤ j ⊦ vals = [], r = jvmref, is_bytevalue(vals[i→n(j)])
