Proof step 5 from proof extension-01 (previous step)

0 ≤ st[r -- _length] .intval ∧ st[r -- _length] .intval = st0[r0 -- _length] .intval ∧ (∀ j. ¬ j < 0 ∧ ¬ st[r -- _length] .intval ≤ j → st[r -- j '] .byteval = st0[r0 -- j '] .byteval) ⊦ ¬ st[r -- _length] .intval < 0 ∧ st[r -- _length] .intval = st0[r0 -- _length] .intval ∧ (0 ≤ j ∧ j < st[r -- _length] .intval → st[r -- j '] .byteval = st0[r0 -- j '] .byteval), ¬ 0 < st[r -- _length] .intval ∧ ¬ 0 < st0[r0 -- _length] .intval

Proof step 4:
st[r -- _length] .intval = st0[r0 -- _length] .intval, 0 < st0[r0 -- _length] .intval, 0 ≤ j, 0 ≤ st0[r0 -- _length] .intval, j < st0[r0 -- _length] .intval, ∀ j. ¬ j < 0 ∧ ¬ st0[r0 -- _length] .intval ≤ j → st[r -- j '] .byteval = st0[r0 -- j '] .byteval ⊦ st[r -- j '] .byteval = st0[r0 -- j '] .byteval
