Re: create image application

I gather that you want to save resources with the application that you can
use when the application is launched. There is a relevant example in the
Binhex folder inside the Examples folder that comes with the MCL distribution.

The code fragment below copies resources from MCL  and 
ccl:examples;binhex;binhex resources.rsrc into the current
"work" space in preparation for a save-application. You'll need
to copy your resources using a similar technique. If you don't do
this then after saving your application, all of the pointers to the 
resources will be "dead" macptrs.

If you don't use this method, then you'll have to keep the resources
in an other file and open the resource file(s) to access them. By
using the other method, you can avoid this step.


; The resource file contains icon ("ICN#", "icl8", etc.) resources for the
; application (id #128) and for the documents that it creates (id #129)
; and appropriate "FREF" and "BNDL" resources.
; MCL contains a resource of type "CCL2" and icon and "FREF" resources for
; a larger set of document types (ids in the range 128-132).
    (with-open-resource-file (f "ccl:examples;binhex;binhex resources.rsrc")
      (do* ((id 128 (1+ id)))
           ((> id 132))
        (dolist (type '("FREF" "ics#" "ICN#" "icl4" "icl8" "ics4" "ics8"))
          (push (list (if (<= id 129) (load-and-detach type id)) type id) 
      ; We don't want a "CCL2" resource ...
      (push (list nil "CCL2" 0) resources)
      ; We -do- want a resource of type binhex-file-creator ...
      (push (list (#_NewHandle 0) binhex-file-creator 0 "MCL Binhex Example") 
      ; Grab "BNDL"(128) from our resource file, replacing MCL's
      (push (list (load-and-detach "BNDL" 128) "BNDL" 128) resources))
      (save-application path :init-file nil :toplevel-function #'binhex-startup
                        :creator binhex-file-creator :resources resources
