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

n < i→n(j), 0 < j ⊦ (intvalues(getarray(r, i, j, st))[n]) = st[r -- (i + n→i(n)) '] .intval, j = 0

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 4:
⊦ m < # vals → (intvalues(vals)[m]) = vals[m] .intval
Proof step 5:
⊦ 0 < j → # getarray(r, i, j, st) = i→n(j)
Proof step 13:
n < # getarray(r, i, j, st), n < i→n(j), 0 < j ⊦ (getarray(r, i, j, st)[n]) .intval = st[r -- (i + n→i(n)) '] .intval, j = 0
