Proof step 7 from proof addobj-getintarray (previous step)

⊦ r = r0, getintarray(r, addobj(r0, class, fis, st)) = getintarray(r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 1:
⊦ getintarray(r, st) = getintarray(r, 0, st[r -- _length] .intval, st)
Proof step 6:
⊦ r = r0, getintarray(r, 0, (addobj(r0, class, fis, st)[r -- _length]) .intval, addobj(r0, class, fis, st)) = getintarray(r, st)

Rule argument

[speclemmaarg: ,getintarray(r, st) = getintarray(r, 0, st[r -- _length] .intval, st) ,[st, r] → [addobj(r0, class, fis, st), r] ,F ,storearrays , ,getintarray-def ]
