Proof step 17 from proof datasize-subarray0-h (previous step)

m ≤ # buf, m0 ≤ m, m0 ≤ # buf ⊦ datasize(subarray(buf, 0, m), m0) = datasize(buf, m0)

Heuristic structural induction applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ datasize(buf, 0) = 0

Rule argument

term: m0
