Proof step 4 from proof getbar-onlyModified (previous step)

st[r1 -- _length] .intval = st0[r1 -- _length] .intval, onlyModified(str, r, st, st0), okbytearray(r1, st), okbytearray(r, st) ⊦ r = r1, getbytearray(r1, 0, st0[r1 -- _length] .intval, st) = getbytearray(r1, 0, st0[r1 -- _length] .intval, st0), junkref(str, r0, st)

User applied rule insert lemma

And obtained the following new goals

Proof step 3:
⊦ 0 ≤ i ∧ 0 ≤ j ∧ r ≠ r1 ∧ okbytearray(r, st) ∧ okbytearray(r1, st) ∧ onlyModified(str, r, st, st0) → getbytearray(r1, i, j, st) = getbytearray(r1, i, j, st0)

Rule argument

[LEMMAARG : getbar-onlyModified-all, [i, j, r, r1, st, str, st0] → [0, st0[r1 -- _length] .intval, r, r1, st, str, st0]]
