Proof step 14 from proof getintarray-in (previous step)

n < # getarray(r, 0, st[r -- _length] .intval, st), 0 < st[r -- _length] .intval, n < i→n(st[r -- _length] .intval) ⊦ st[r -- _length] .intval = 0, (getarray(r, 0, st[r -- _length] .intval, st)[n]) .intval = st[r -- n→i(n) '] .intval ∧ ¬ st[r -- _length] .intval ≤ n→i(n)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 8:
⊦ 0 < j → # getarray(r, i, j, st) = i→n(j)
Proof step 13:
0 < st[r -- _length] .intval, n < i→n(st[r -- _length] .intval) ⊦ st[r -- _length] .intval = 0, (getarray(r, 0, st[r -- _length] .intval, st)[n]) .intval = st[r -- n→i(n) '] .intval ∧ ¬ st[r -- _length] .intval ≤ n→i(n)
