5.3. LOOP MACROS FOR ACCESSING SINGLE INPUT OBJECTS 695.3 Loop Macros for Accessing Single Input ObjectsThis section describes two macros that ease accessing all iconic objects and image componentswithin an input object parameter, see Fig. 5.15. Please see also the additional loop macros insection 6.1 that further facilitate programming typical supply procedure.NamesÀÐÐǸ ÀÐÐÓÑÔSynopsisÒÐÙ ÀÐÓÒºÀÐÐÇ´ ÀÔÖÓÒÐÁÆÌÀÝÁÆÌÀÐÐÓÑÔ´ÀÔÖÓÒÐÀÝÀÝÀÑÁÆÌÔÖÓÒиÔÖÒÙѸ²Óݸ²ÒܵÔÖÓÒиÓݸ²ÑÒݸ²ÑÒ¸²ÒܵFigure 5.15: Basic loop macros to access iconic objects. “&” denotes output parameters of themacros.
