This structure declaration would be necessary to create a doubly-linked 
list.  More meaning variable name would be

struct TListObject
{
   ...
   TListObject *PrevListObject; // At the head of the list this is NULL.
   TListObject *NextListObject; // At the tail of the list this is NULL.
};

It has been a long time since I've used such a structure.
