Disclosed is a methodology by which OS/2* Presentation Manager* (PM) messages are more efficiently routed to a targeted PM application procedure. This new methodology provides a more efficient manner in which to send messages and also expands the scope of message transfer. OS/2 PM allows PM applications to communicate between procedures through the WinSendMsg function. But, this communication is only allowed from one PM application procedure to itself or one of its parent processes by which it was created and given control. Furthermore, if a programmer has a procedure that needs to communicate with other PM procedures, not only must the procedure be developed but also a procedure window be coded because PM only communicates through these procedure windows out to the actual procedure that will processes the PM message.
