I've got an annoying little problem that I was hoping someone can help me solve. I have a Module, NDelaySolve, which returns a numerical approximation of solutions to differential-delay equations. In order to make the output look as much like that of NDSolve as possible, I have the module return something like {{x[t] -> g[t], y[t] -> f[t]}} where g[t] and f[t] are often big Which[] functions. I would like to reduce the output by creating a DelaySolveFunction[][t] which looks something like an Interpolating function. Here is an example: In[4]:= Format[spam[x_]] := 1/x; In[8]:= spam[a_] := Module[{}, pop = Table[a,{3}] ]; In[9]:= spam[8] Out[9]= {8, 8, 8} This Format isn't doing what I want. I would like spam[8] to return {8,8,8} but to print the output as 1/8. If I get this one to work, I could solve my real problem. Scott Herod sherod at newton.colorado.edu
