Check Mark and Hierarchical Menus

[alms@cambridge.apple.com (Andrew L. M. Shalit)]

   The menu-item function "set-menu-item-check-mark" doesn't seem
   to work with hierarchical menus.  Is there any way I can set a
   check-mark on a hierarchical menu-item?

The Macintosh Operating System does not support check-marks on
a hierarchical menu.  (You can put check-marks on the items of
a hierarchical menu, but not on the menu itself).  This is
because the storage for the check-mark and the command-key
was used to implement a pointer to the sub-menu.  (remember,
they needed backward compatibility with all this compiled code
which was *sure* it knew just what menu records looked like.)
