And, to respond to your question :) : You can returne from C and of the primitive types accepted by VFP. To return a string:

char* myfunc()
{
   //-- It's important to allocate the string dynamically
   char* mystring = malloc(100);

   // do something with mystring

   return mystring;
}

You just can't returned a structure as a string (because of that chr(0)).
