Of course pascal wants a type, so they use a base type: Pointer. Now I want to store PtrInt. And the other way round. So, I must type case from one to the other and back. With templates or some include file tricks I could probably avoid the problem. > > What type has Pointer-Pointer? > > > > PtrInt Thanks. I thought so.
