TITLE	The Chart Application-Class

MODULE	chartapp.c

VERSION	0.0

AUTHOR	TC Peters
	Information Technology Center, Carnegie-Mellon University 

DESCRIPTION
	This is the suite of Methods that support the Chart Application-Class.

    NB: The comment-symbol "===" indicates areas which are:
	    1 - Questionable
	    OR
	    2 - Arbitrary
	    OR
	    3 - Temporary Hacks
    Such curiosities need be resolved prior to Project Completion...


HISTORY
  01/19/89	Created (TCP)
  05/04/89	Add Major/Minor Version settings (TCP)
  05/10/89	Move im_Create outside im_SetView (macro problem) (TCP)
  05/31/89	Add classID parameter in FinalizeObject (TCP)
  09/01/89	Use super_ParseArgs (TCP)
  09/07/89	Remove Open-msg for non-existent new file (TCP)
