  A string motivated, N=1 global supersymmetric, general Lagrangian is obtained
that represents an inflaton interacting with the modes of a string. Focus is
placed on the Lagrangian's relevance to warm inflation, which is a cosmology
based on dissipative dynamics. Several interaction schemes are identified from
the general Lagrangian that may have interesting consequences for dissipative
dynamics. Distributed-mass-models, which have been shown to solve the horizon
problem within a warm inflation regime, are identified in the general
Lagrangian.
