This article describes a method that will allow a set of applications or subsystems to converse across address space boundaries of the MVS operating system, regardless of protect key or operating priority. The conversation may occur on a one-to-one or one-to-many basis. It eliminates the need for the higher overhead cross-memory services in many situations. A need exists to interchange information between separate applications. In many cases, there is no requirement for an immediate information request-wait-answer type of protocol. An example where this would be true is if one of the applications was a monitor that reported on the performance status of other applications running in the same computer. The information desired is only time dependent within a particular time interval. That interval could be minutes.
