(1) The following example executes different functions based on the presence or the absence of a Page break:

      `Setting the selection
   WR SET SELECTION (area;0;0)
      `Try to select the first page break
   WR SELECT (area;7;1)
      `Retrieving the limits of the new selection
   WR GET SELECTION (area;$vlbegin;$vlend)
   If (($vlbegin=0) & ($vlend=0))
         `There is no page break
   Else
         `Do something with the page break
   End if

(2) The following example selects the references in the 4D Write area referenced by area and applies to them a style that makes them easy to spot:

   NbObjects:=WR Count(area;4)
      `Counting the number of references
   For (i;1;NbObjects)
      WR SELECT(area;1;i)
         `Selecting each reference
      WR GET REFERENCE(area;TableNo;FieldNo;vName;vType)
      WR SET TEXT PROPERTY(area;wr bold;1)

      WR SET TEXT PROPERTY(area;wr text color;wr blue)
         `Applying Blue and Bold to the selection
   End for

WR Count, WR Replace, WR SELECT PICTURE IN PAGE.
