 If(vUniform=0) `If there are several fonts in the current selection

    CONFIRM("There are several fonts in the selection, the font used for the last "+"character is

    "+vFont+". OK to apply this font to the entire document?")

 Else

    CONFIRM("The font of the selection is "+vFont+". OK to apply this font to the entire document?)

 End if

 If(OK=1)

    WR EXECUTE COMMAND(Area;wr cmd select all) `Selecting the entire document

    WR SET FONT(Area;vFont) `Applying the new font

  `Moving the insertion point to the beginning of the document

    WR SET SELECTION(Area;0;0)

    WR SCROLL TO SELECTION(Area) `Displaying the current text selection

 End if
