Proof step 15 from proof compatarray-isarray (previous step)

st[r -- _type] .type = mkarraytype(ty), st[r -- _length] = intval(i), 0 ≤ i, r -- _length ∈ st, is_arrayref(r, i, st), r ∈ st, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → compat(str, st[r -- j '], ty, st) ⊦ r = jvmref, r ≠ jvmref ∧ r -- _type ∈ st ∧ is_typevalue(st[r -- _type]) ∧ is_arraytype(st[r -- _type] .type) ∧ okarray(r, st[r -- _type] .type .type, st)

Proof step 14:
st[r -- _length] = intval(i), st[r -- _type] .type = mkarraytype(ty), r -- _type ∈ st, is_typevalue(st[r -- _type]), r ∈ st, is_arrayref(r, i, st), r -- _length ∈ st, 0 ≤ i, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → compat(str, st[r -- j '], ty, st) ⊦ r = jvmref, okarray(r, ty, st)
