Proof step 81 from proof fits-put (previous step)

∀ st, r, r1, i, by, str. is_referencevalue(st[r -- sks0]) ∧ fits(r, sks0, st) ∧ okarray(r1, byte_type, st) ∧ r1 ∈ st → (st[r1 -- i ', byteval(by)][r -- sks0]) = st[r -- sks0] ∨ r1 = jvmref ∨ junkref(str, r, st), is_referencevalue(st[r -- (sk + sks0)]), fits(r, sk + sks0, st), okarray(r1, byte_type, st), r1 ∈ st ⊦ (st[r1 -- i ', byteval(by)][r -- (sk + sks0)]) = st[r -- (sk + sks0)], r1 = jvmref, junkref(str, r, st)
