Writing The 'access_data_next' Macro

• We define the macro using the 'define' block:

  define access_data_next
          if $ad_curr == 0
                  print "(null list)"
          else
                  if $ad_curr->next == 0
                          print "(null next)"
                  else
                          set $ad_curr = $ad_curr->next
                          print *(struct access_data*)$ad_curr->data
                  end
          end
  end
