The rexxpg book lists in "Chapter 4. The Basics of Classes" all ooRexx classes.
The listing is not
correctly indented as the root class Object is not shown as the topmost class.
Before correcting anything I also created a little program that would create
the ooRexx class tree
automatically.
While doing so, it would become possible to add additional information to the
listed classes, e.g.
whether a class is a mixin and for classes using multiple inheritance which
classes they inherit
(maybe in parentheses and in italic). The motivation would be to have
So here are both renderings (there classes for which questions are formulated
at the bottom are
highlighted in red):

Questions:
1. What is the purpose of the classes: BagMixin, ManyItemsMixin, SetMixin and
SupplierMixin?
1. They carry the name "mixin" but are not inherited by the exposed Rexx
classes.
2. They cannot be fetched via their environment name like .BagMixin.
3. Should they be listed in the class object's SUBCLASSES array at all?
2. Should the classes ArgUtil and LocalServer be documented or left out?
1. ArgUtil was never documented and supposedly Validate is the successor
and should be used
instead.
2. If LocalServer should get documented, where could I find the respective
information?
3. Should the classes OLEObject and OLEVariant be documented or left out?
(They only exist in the
Windows version and are documented separately in the Windows reference
book.)
4. Should the short or the long form be usedj, which informs about multiple
inheritance related
classes?
