Proof step 29 from proof putBar-rew (previous step)

j < i ∨ i + n→i(# bytes) ≤ j ⊦ ((rk = r -- j ' ⊃ val; putByteArray(bytes, r, i, st)[rk])) = (putByteArray(bytes, r, i, st[r -- j ', val])[rk])

Heuristic if-then-else split applied rule case distinction

And obtained the following new goals

Proof step 6:
rk = r -- j ', j < i ∨ i + n→i(# bytes) ≤ j ⊦ val = (putByteArray(bytes, r, i, st[r -- j ', val])[rk])
Proof step 28:
rk ≠ r -- j ', j < i ∨ i + n→i(# bytes) ≤ j ⊦ (putByteArray(bytes, r, i, st)[rk]) = (putByteArray(bytes, r, i, st[r -- j ', val])[rk])
