Proof step 6 from proof okbar-put-01 (previous step)

¬ (is_bytevalue(st[r0 -- j ']) ∧ okarray(r, byte_type, st)), okbytearray(r, st), okbytearray(r0, st), j < st[r0 -- _length] .intval, 0 ≤ j, 0 < st[r0 -- _length] .intval ⊦ okarray(r, byte_type, st[r -- i ', st[r0 -- j ']])

And obtained the following new goals

Proof step 3:
⊦ okbytearray(r, st) ∧ 0 ≤ i ∧ i < st[r -- _length] .intval → (¬ is_bytevalue(st[r -- i ']) ↔ false)
Proof step 5:
okbytearray(r, st), okbytearray(r0, st), j < st[r0 -- _length] .intval, 0 ≤ j, 0 < st[r0 -- _length] .intval ⊦ okarray(r, byte_type, st[r -- i ', st[r0 -- j ']]), okarray(r, byte_type, st)
