Query: Arbitrarily Accurate Eigenvalues for General Anharmonic Potentials   We show that the Riccati form of the Schrodinger equation can be reformulated
in terms of two linear equations depending on an arbitrary function G. When $G$
and the potential are polynomials, the solutions of these two equations are
entire functions (L and K) and the zeroes of K are identical to those of the
wave function. Requiring such a zero at a large but finite value of the
argument yields the low energy eigenstates with exponentially small errors.
Judicious choice of G can improve dramatically the numerical treatment. The
method yields many significant digits with modest computer means.
