Proof step 7 from proof getArray-rec-01 (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 6:
0 < j ⊦ getarray(r, i, j, st) = getarray(r, i, j - 1, st) + st[r -- (i + j - 1) '] '
