  Standard quantization using, for example, path integration of field theory
models, includes paths of momentum and field reach infinity in the Hamiltonian
density, while the Hamiltonian itself remains finite. That fact causes
considerable difficulties. In this paper, we represent $\pi(x)$ by
$k(x)/\phi(x)$. To insure proper values for $\pi(x)$ it is necessary to
restrict $0<|\phi(x)|<\infty$ as well as $0\leq|k(x)|<\infty$. Indeed that
leads to Hamiltonian densities in which $\phi(x)^p$, where $p$ can be even
integers between $4$ and $\infty$. This leads to a completely satisfactory
quantization of field theories using situations that involve scaled behavior
leading to an unexpected, $\hbar^2/\hat{\phi}(x)^2$ which arises only in the
quantum aspects. Indeed, it is fair to claim that this symbol change leads to
valid field theory quantizations.
