Proof step 7 from proof okbar-put-01 (previous step)

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 ']])

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ is_bytevalue(val) ∧ okarray(r, byte_type, st) → okarray(r, byte_type, st[r -- i ', val])
Proof step 6:
¬ (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 ']])

Rule argument

[crewrite-arg: okarray-put-06 , F , [val, i, st, r] → [st[r0 -- j '], i, st, r] ]
