Proof step 7 from proof getarray-put-06 (previous step)

⊦ fs ' = _type, fs ' = _length, getarray(r0, st[r0 -- fs ', val]) = getarray(r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ getarray(r, st) = getarray(r, 0, st[r -- _length] .intval, st)
Proof step 6:
⊦ fs ' = _type, fs ' = _length, getarray(r0, 0, (st[r0 -- fs ', val][r0 -- _length]) .intval, st[r0 -- fs ', val]) = getarray(r0, st)

Rule argument

[crewrite-arg: getArray-all, F, [st, r] → [st[r0 -- fs ', val], r0]]
