I don't think so. I have struggled with this quite a bit, and never got a satisfactory solution from this or any other source. Someone will probably mention Van's separation of interface and implementation. Were that adopted, it would solve my problems. Some sort of rudimentary version of B containing a dummy for P might WORK, but it is not standard. The USEd modules have to be available when the routine using them is compiled. As it turns out, I will be returning to this problem soon, hopefully this week. You'll probably hear cries of desperation from me then! %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
