I am converting a Borland C++ (with OWL) application into
Visual C++ with MFC.  One of the classes in the Borland appl is derived from 'sortable'.  The Borland on-line help says that 'sortable' are "used to create class of objects that are sortable".  I've no idea what this means.  Anyway, the question is what is the equivalent in VC++?

I have used OWL for 3 years, but I never found this kind of "sortable" class. Maybe are you referring to a derived class from TSortedArray or similar? In this case there is no equivalence in MFC. I have written my own sortable classes using MFC templates and by adding a sort routine.

Sortable is a reserved word recognised by Borland C++.  Here is what the on-line Help has to say about Sortable.....
=================================================================

Use Sortable to create classes of objects that are sortable. Membership in this class is limited to objects that can be tested for order.

You can derive objects from Sortable and place them into ordered collections. An object derived from Sortable must define isLessThan, and isEqual in addition to those functions required by the class Object.

The type of sortable objects available differs between the Object-based containers and the template-based containers.

In the Object-based hierarchy you must use objects ultimately derived from Sortable, whereas the template containers let you store any object or predefined data type for which == and < is defined.

If you want to store ints in an Object-based container, you must invent a suitable class.
=================================================================

Would you mind giving me the source code for your sortable classes?
