Proof step 5 from proof okarray-addobj (previous step)

⊦ r = r0, okarray(r, int_type, addobj(r0, class1, fis, st)) ↔ okarray(r, int_type, st)

User applied rule structural induction

And obtained the following new goals

Proof step 1:
⊦ addobj(r, class1, [], st) = st[r -- _type, typeval(mkclasstype(class1))]
Proof step 4:
∀ r, r0, class1, st. r = r0 ∨ (okarray(r, int_type, addobj(r0, class1, fis0, st)) ↔ okarray(r, int_type, st)) ⊦ r = r0, okarray(r, int_type, addobj(r0, class1, fv + fis0, st)) ↔ okarray(r, int_type, st)

Rule argument

[VARWITHVARSEQSARG : fis, ()]
