Proof step 11 from proof isobj-put-03 (previous step)

st[r -- _type] = typeval(mkclasstype(class0)), r ∈ st, r -- _type ∈ st, okval(val, ty), sk ∈ instfields(class0), sk ∈ instfields(class0) → goodfieldandtype(r, sk, st) ⊦ r = jvmref, ty = void_type, goodfieldandtype(r, sk, st[r1 -- mkfs(class, ty, fieldvar) ', val])

Proof step 10:
st[r -- _type] = typeval(mkclasstype(class0)), r ∈ st, r -- _type ∈ st, okval(val, ty), sk ∈ instfields(class0), is_fskey(sk), r -- sk ∈ st, okval(st[r -- sk], sk .fs .type) ⊦ r = jvmref, ty = void_type, okval(st[r1 -- mkfs(class, ty, fieldvar) ', val][r -- sk], sk .fs .type)
