Summary:O29; For a discontinuous Toda medium,a differential-difference equation (DDE) can be established.A modification of the exp-function method is applied to construct some soliton-like and period-like solutions for nonlinear DDEs with variable coefficients.The solution process is simple and straightforward and some new solutions are obtained with full physical understanding.
