Proof step 54 from proof arrayMaxWhile (conclusion)

st[_mode] = noval, okarray(a, int_type, st), init(st), getintarray(a, st) ≠ [] ⊦ 〈st; i = swt.ArrayMax.max(a); 〉 (st[a -- i '] .intval = max(getintarray(a, st)) ∧ 0 ≤ i ∧ i < st[a -- _length] .intval)

Proof step 53:
st[_mode] = noval, getintarray(a, st) ≠ [], a ≠ jvmref, okarray(a, int_type, st), init(st), a ∈ st ⊦ 〈st; i = swt.ArrayMax.max(a); 〉 (st[a -- i '] .intval = max(getintarray(a, st)) ∧ 0 ≤ i ∧ i < st[a -- _length] .intval)
