Proof step 8 from proof booleanarray-get (conclusion)

⊦ okarray(r, boolean_type, st) ∧ 0 ≤ i ∧ i < st[r -- _length] .intval → (getbooleanarray(r, st)[i→n(i)] ↔ st[r -- i '] .boolval)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ getbooleanarray(r, st) = getbooleanarray(r, 0, st[r -- _length] .intval, st)
Proof step 2:
⊦ getbooleanarray(r, i, j, st) = booleanvalues(getarray(r, i, j, st))
Proof step 7:
okarray(r, boolean_type, st), i < st[r -- _length] .intval, r ∈ st, 0 ≤ i, 0 < st[r -- _length] .intval ⊦ booleanvalues(getarray(r, 0, st[r -- _length] .intval, st))[i→n(i)] ↔ st[r -- i '] .boolval, r = jvmref
