Proof step 5 from proof getArray-rec-01 (previous step)

j = i0 + 1, 0 < j ⊦ getarray(r, i, j, st) = getarray(r, i, i0, st) + st[r -- (i + j - 1) '] '

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 4:
0 ≤ i0 ⊦ getarray(r, i, i0 + 1, st) = getarray(r, i, i0, st) + st[r -- (i + i0) '] '

Rule argument
