    A new strategy of the use of PT symmetry in quantum theory is proposed. The essence of the innovation lies in the replacement of the usual parity-like choice of P by its non-involutory and positive-definite alternative P-(positive) not equal I. The resulting modified concept of P-(positive) T -symmetry remains phenomenologically appealing as well as technically useful. This is demonstrated and illustrated via an N-site quantum lattice model which is exactly solvable in terms of Legendre polynomials.
