Proof step 2 from proof read-get (previous step)

n < # ax ⊦ fs[ax][n] = fs[ax[n]], ax = []

User applied rule structural induction

And obtained the following new goals

Proof step 3:
n < #(adr + ax0), ∀ n, fs. n < # ax0 → fs[ax0][n] = fs[ax0[n]] ∨ ax0 = [] ⊦ adr + ax0 = [], fs[adr + ax0][n] = fs[(adr + ax0)[n]]

Rule argument

indvar: ax
