Proof step 18 from proof okarray-primput (previous step)

st[r -- _type] .type = mkarraytype(ty), 0 ≤ j, 0 < st[r -- _length] .intval, okprimtype(val, ty), j < st[r -- _length] .intval, r -- _type ∈ st, is_typevalue(st[r -- _type]), r -- _length ∈ st, is_arrayref(r, st[r -- _length] .intval, st), j0 < st[r -- _length] .intval, r ∈ st, 0 ≤ st[r -- _length] .intval, 0 ≤ j0, ∀ j1. ¬ j1 < 0 ∧ ¬ st[r -- _length] .intval ≤ j1 → oktype(st[r -- j1 '], ty, st) ⊦ r = jvmref, oktype((j0 = j ⊃ val; st[r -- j0 ']), ty, st)
