Query: Masslesslike minimal subtraction for massive scalar field theory   We introduce the simplest minimal subtraction method for massive $\lambda
\phi^{4}$ field theory with $O(N)$ internal symmetry, which resembles the same
method applied to massless fields by using two steps. First, the utilization of
the partial-$p$ operation in every diagram of the two-point vertex part in
order to separate it into a sum of squared mass and external momentum,
respectively, with different coefficients. Then, the loop integral which is the
coefficient of the quadratic mass can be solved entirely in terms of the mass,
no longer depending upon the external momentum, using the {\it parametric
dissociation transform}. It consists in the choice of a certain set of fixed
values of Feynman parameters replaced inside the remaining loop integral after
solving the internal subdiagrams. We check the results in the diagrammatic
computation of critical exponents at least up to two-loop order using a flat
metric with Euclidean signature.
