I just go a new Sun 3/60 at work ;-), and at the moment, I'm
playing around with SunView.  I was previously programming
application enhancements on an obscure CAD station that had
absolutely ZIP when it comes to nice environments such as
SunView.  What a difference!!
Anyway, I'm really impressed with the way you create "objects" in
SunView.  If I want a panel in a window, I can:

panel = window_create(frame, PANEL, 0);

and I get a panel with a bunch of default values.  Or, I can:

panel = window_create(frame, PANEL,
		      WIN_X, 		10,
		      WIN_Y,		20,
		      WIN_COLUMNS,	55,
		      WIN_ROWS,		60,
		      0);

and I get a panel with the parameters I specified.  Seems to me
that this kind of thing would be great for programming "objects"
in intuition, such as windows and screens (for example).  It'd
be nice to just have a function that opens a window with default
values if I specify the minimum number of arguments, but also
be able to call the same function with a lot of arguments when
I want something other than the default window/screen/etc. that
is provided by the function.

So, my question really comes down to this:  is there anything in
Lattice 4.0 similar to varargs() in Unix?  Writing "generic"
functions such as "CreateWindow()" would sure benefit from
a variable number of arguments.
