I am thinking something like this, in the Parse_Num_Factor() function in 
express.c:

#include "isosrf.h"

...

    CASE(FUNC_ID_TOKEN)
    {
        DBL result = 0;
        int i=0;
        VECTOR Point;
        FUNCTION * TFunc = NULL;

        Load_Function(TFunc, ((FUNCTION *)Token.Data)->func_name);/*?*/
        
        GET(LEFT_PAREN_TOKEN)
        Parse_Vector(Point);
        GET(RIGHT_PAREN_TOKEN)
        if(TFunc != NULL)
            result = (TFunc->iso_func)(TFunc, Point);
        
        for(i=0; i < *Terms; i++)
            Express[i] = Val;
    }
    END_CASE

I don't know if this will work(it compiles, but it hasn't been tested), 
and I have no idea what Load_Function() does...but it's a start.
