The Basics of Classes

Similar objects in Rexx are grouped into classes, forming a hierarchy. Rexx gives you a basic class hierarchy to start with. All of the classes in the hierarchy are described in detail in the Open Object Rexx: Reference .

Rexx provides the following classes on all operating systems by default. The classes are depicted in hierarchical order, subclasses get indented under their superclass. If a class can be used for multiple inheritance it gets flagged with (mixin). Classes that inherit from mixin classes will list them in parantheses starting with the word inherit followed by the blank delimited list of inherited mixin classes.

Note that there might also be other classes available, depending on the operating system.
