    PRINT("Il file richiesto non esiste .....")
END EXCEPTION

BEGIN
    FERROR%=FALSE
    PRINT("Nome del file";)
    INPUT(FILE$)      ! chiede il nome del file
    OPEN("I",1,FILE$) ! apre un file sequenziale in lettura
      IF NOT FERROR% THEN
         REPEAT
           INPUT(LINE,#1,CH$)   ! legge una riga ....
           PRINT(CH$)           ! ... la stampa ...
