Ian,
 
You will find three things useful for working with icons:
 
1.  A copy of Inside Macintosh (at least volumes 1 and 2), which contains all
the info about using resources and icons
 
2.  The newly revised file Resources.lisp, which is I believe available in the
/pub/MCL2/contrib pathway of the Cambridge archive, under the names
resources.lisp-readme.text
resources.lisp.cpt.hqx
 
3.  In ToolUtils.lisp, the interfaces file,
 
(deftrap _geticon ((iconid :signed-integer))
   (:stack :handle)
   (:stack-trap #xA9BB))
 
(deftrap _ploticon ((therect :rect) (theicon :handle))
   nil
   (:stack-trap #xA94B))
 
Essentially, with an icon you need to read the resource into memory [easiest
using the stuff in resources.lisp], then manipulating the icon as a handle
(from the resource reading), call _ploticon() to draw it.
 
Bitmaps are a bit more complex, in that having created your bitmap (or read it
in) you then need to copy it into part of the active view.  Again, Inside Mac
is a useful series of volumes.
 
Let me know if I can be of more help,
 
Regards, Howard.
