My bad

Should have been

FUNCTION dvariable Richards(...)

I don't think your suggestion will work, Steve (he said without having tried it). If I understand things correctly (going out on a looong limb here), "FUNCTION" is an identifier to the tpl2cpp translator that what follows is a function that 1) whose signature should be added to the model_parameters class declaration in tpl_name.htp and 2) whose implementation should be added to tpl_name.cpp.

A nice (but probably tough to implement) feature in tpl2cpp would be the ability to put the following:

FUNCTION dvariable model_parameters::Richards(const dvariable &age, const dvariable &Linf, const dvariable &K, const dvariable &t0, const dvariable &p)
    dvariable Length=Linf*pow((1+(1/p)*exp(-K*(age-t0))),-p);
    return(Length);

into a file (functions.cxx, say) and be able to "include" that text in the tpl you're converting to cpp at a stage in the process before FUNCTIONs get converted to cpp equivalents. If such a feature is currently available, I haven't found it.

Why do I get an error if I put the following function in the file CAPAM_Growth.hpp and include it using #include<CAPAM_Growth.hpp> but if I put it in the tpl using the FUNCTION section I do not? The translator appears to just put it in the cpp with no changes

dvariable model_parameters::Richards(const dvariable &age, const dvariable &Linf, const dvariable &K, const dvariable &t0, const dvariable &p)
{
  {
    dvariable Length=Linf*pow((1+(1/p)*exp(-K*(age-t0))),-p);
    return(Length);
  }
}

The errors I get are
