Proof step 3 from proof datasize-samebuf-h (previous step)

m < n, datasize(buf, n) < datasize(buf, m), m < # buf, n ≤ # buf ⊦

User applied rule structural induction

And obtained the following new goals

Proof step 4:
m < # buf, datasize(buf, n0 +1) < datasize(buf, m), m < n0 +1, n0 +1 ≤ # buf, ∀ m, buf. ¬(m < n0 ∧ datasize(buf, n0) < datasize(buf, m) ∧ m < # buf ∧ n0 ≤ # buf) ⊦

Rule argument

indvar: n
