Proof step 13 from proof getbytearray-mkjavavalues (previous step)

0 < st[r -- _length] .intval, st[r -- _length] .intval ≤ n→i(n), okbytearray(r, st), n < i→n(st[r -- _length] .intval) ⊦ st[r -- _length] .intval = 0, mkjavavalues(bytevalues(getarray(r, 0, st[r -- _length] .intval, st))) = getarray(r, 0, st[r -- _length] .intval, st), n = 0, is_bytevalue(getarray(r, 0, st[r -- _length] .intval, st)[n])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 11:
0 ≤ i ⊦ ((* i)) ≤ n→i(n) ↔ i→n(i) ≤ n
Proof step 12:
⊦ okbytearray(r, st) → ¬ st[r -- _length] .intval < 0
