If you are using R4GL you need to link the functions into a custom runner (and add them to the user functions header file). If using I4GL just compile and link. There are full instructions for making functions 4GL callable in C and for making custom R4GL runners and Interactive Debugger runners. Similar for D4GL. RT{Fine}M. Art S. Kagel
