140  Pascal User Manual  12.D.  The Procedure Page  As a convenience for formatting  tt  xtfiles, Pascal has a predefined  Page  procedure.  Page (F)  is intended tn cause subsequent text written on  F  to appear on a new "page" (if  F  ii,  printed or displayed, etc.).  Page (F)  causes an implemenlation-defined action on the file  F.  In  most  implementations,  Page (F  writes  the  appropriate  control  characters (such as an ASCII Form Feed) to cause the desired effect.  Noles:  If Page (F)  is invoked and the last operation on  F  was not  Writeln (F)  then  Page (F)  pert,)rms an implicit  Writeln (F)  as its  first action.  F  must be defined an(  I  in generation mode or else  Page (F)  is an error. The effect of reading  II  file  F  to which  Page (F)  has been  applied is implementation-depenclent.
