This section is a moving target. As Scheme is case insensitive, the upper-case version may be used and probably should to make the code look more like conventional Windows code. The Scheme bindings have been produced automagically. The set of procedures is incomplete because procedures have been added on a by-need basis for the implementation of other parts of the system, e.g. Scheme Graphics. Look in the implementation for further details.
Predicates beginning with Is finally have a question-mark appended.
