Proof step 23 from proof validref-putbar (previous step)

validref(str, r, ty, st), okbytearray(r0, st) ⊦ r = r0, validref(str, r, ty, putByteArray(bytes, r0, i, st))

User applied rule structural induction

And obtained the following new goals

Proof step 22:
∀ str, r, ty, st, r0, i. validref(str, r, ty, st) ∧ okbytearray(r0, st) → r = r0 ∨ validref(str, r, ty, putByteArray(bytes0, r0, i, st)), validref(str, r, ty, st), okbytearray(r0, st) ⊦ r = r0, validref(str, r, ty, putByteArray(by + bytes0, r0, i, st))

Rule argument

[VARWITHVARSEQSARG : bytes, ()]
