Proof step 12 from proof getbar-lastrec (conclusion)

⊦ 0 < j → getbytearray(r, i, j, st) = getbytearray(r, i, j - 1, st) + st[r -- (i + j - 1) '] .byteval

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
0 < j ⊦ getbytearray(r, i, j, st) = getbytearray(r, i, j - 1, st) + st[r -- (i + j - 1) '] .byteval '

Rule argument
