Proof step 8 from proof getBar-2-put (previous step)

⊦ getbytearray (r, 0, (st[r -- _type, typeval(mkarraytype(byte_type))][r -- _length, intval(2)][r -- 0 ', byteval(by)][r -- 1 ', byteval(by0)][r -- _length]) .intval, st[r -- _type, typeval(mkarraytype(byte_type))][r -- _length, intval(2)][r -- 0 ', byteval(by)][r -- 1 ', byteval(by0)]) = by ' + by0 '
