   _PLINENO = 56
   m.counter = 1
   m.numfonts = ALEN(fonts,1)
   DO WHILE m.counter <= m.numfonts
      m.this_font = LTRIM(fonts(m.counter))
      SET CONSOLE ON
      @ 12,39 SAY SPACE(20)
      @ 12,39 SAY m.this_font
      SET CONSOLE OFF
      m.sizes = AFONT(sizes,(m.this_font))
      IF _PLINENO > 52
         DO rpthead
      ENDIF
      ?
