Proof step 4 from proof getbar-restn-02 (previous step)

n→i(n) ≤ st[r -- _length] .intval ⊦ # getbytearray(r, n→i(n), st[r -- _length] .intval - n→i(n), st) = i→n(st[r -- _length] .intval - n→i(n))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 3:
⊦ 0 ≤ j → # getbytearray(r, i, j, st) = i→n(j)

Rule argument

[crewrite-arg: bar-len-02 , F , [st, j, i, r] → [st, st[r -- _length] .intval - n→i(n), n→i(n), r] ]
