 -> Can anyone out there share their experiences in working with this
 -> "mind switch"?  I'm not sure about Unix, but the Mac does work under
 -> this Message Processing architecture.  How does this work with
 -> Forth's KEY and EXPECT?

         The Amiga, a fully-multitasking operating system, has a message-
 based architecture.

         Like many multitasking systems, an Amiga application should
 Wait(messages_mask) in between activities.

         The trick is that in a GUI you have to set the bits for several
 different types of messages and be ready to handle them when they come
 in. So even simple words like KEY before they call Wait() have to set
 several different bits (keystroke, mouse select, close button, etc) that
 indicate what kind of messages they are willing to accept.

         Then when a message *does* come, they have to process whatever
 message it might be within the range of messages they were willing to
 accept.

         If you get too frazzled, Dennis, you oughta look at contracting
 this out :-)
