Separate entities in the BOOL environment communicate via message-passing, just as BOOL program objects do (and to a large extent, just as BOOL operates internally). As such, messaging is a native feature of the RTE and is supported in two basic forms.

Essentially, the BOOL RTE is like an operating system. It provides a set of standard systems available to running BOOL programs. The intent is that, as with Java and other platform-agnostic languages, BOOL programs are highly transportable to any platform with a BOOL RTE.
