Proof step 10 from proof getbar-3rec (previous step)

j = i0 + 3, 3 ≤ j, 0 < j, 0 ≤ j ⊦ bytevalues(getarray(r, i, j, st)) = st[r -- i '] .byteval ' + st[r -- (i + 1) '] .byteval ' + st[r -- (i + 2) '] .byteval ' + bytevalues(getarray(r, i + 3, i0, st))

And obtained the following new goals

Proof step 9:
0 ≤ i0 ⊦ bytevalues(getarray(r, i, i0 + 3, st)) = st[r -- i '] .byteval ' + st[r -- (i + 1) '] .byteval ' + st[r -- (i + 2) '] .byteval ' + bytevalues(getarray(r, i + 3, i0, st))
