Proof step 10 from proof initialization (previous step)

mtd-cons(pebs), ubi-io-initial(pebs) ⊦ ⟨choose err0 with ⌊err0⌋ ∨ err0 = ESUCCESS in err := err0; if err = ESUCCESS then choose apebs0 with ubi-io-initial(apebs0) in apebs := apebs0 else apebs := ?⟩ (abs(pebs, apebs) ∧ ESUCCESS = err)

Heuristic symbolic execution applied rule choose right

And obtained the following new goals

Proof step 11:
