	Numerous products have come on the market in recent years
in the category of Computer-Aided Software Engineering (CASE). These
are systems for building systems.

	CASE tools aid systems developers in the creation and validation
of various types of diagrams. Techniques include DeMarco/Gane and Sarson
dataflow diagrams, state-transition charts, structure charts, Chen or
Martin entity-relationship diagrams, and others. Some even allow you to
define your own symbols and modeling rules to set up your own diagramming
techniques.

	 These tools represent, for a Macintosh user, a paradox: They are
all graphics applications - with mouse, icons, windows, menu bars - and
they all run on IBM PCs.  (This is a slight exaggeration, as there are a
handful running on VAX/VMS, UNIX and IBM MVS, but the vast majority run
under MS-DOS.) What adds to the puzzlement is that these are CPU- and
memory-intensive applications; some won't boot in 640KB of memory, while
others "will run on a 286 machine, but we URGE you to consider a 386-
based platform". So why isn't the Macintosh at the fore, or moving to be,
in this market?

	If you have information or comments, please mail to me; I would
be delighted to be proven incorrect. I'll summarize any responses.
