Proof step 24 from proof subset-len-01 (conclusion)

⊦ st[r -- _length] .intval = i ∧ st ⊆ st0 ∧ exactarray(r, ty, st) → st0[r -- _length] .intval = i

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ exactarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 2:
⊦ st ⊆ st0 ∧ exactarray(r, ty, st) → exactarray(r, ty, st0)
Proof step 23:
r ∈ st, exactarray(r, ty, st0), exactarray(r, ty, st), st ⊆ st0, r ∈ st0 ⊦ r = jvmref, st0[r -- _length] .intval = st[r -- _length] .intval

Rule argument
