sflread command

    (A) Function
        Reading an SFL source and converting it into
        an inner representation of an SFL module class.

    (B) Format

        sflread  <sflsource>  [-exp]

    (C) Parameter
         <sflsource>
           Designate an SFL source file name.

    (D) Notes
        It is not allowed to directly simulate an inner representation
        of an SFL module class with this command only.
        You need to create a simulation image with the install
        command to do simulating.

        If there is something wrong with an SFL source file, 
        the following message is output during the execution of this command:
        
      Error detected ! Shall I open the edit pad ? Type <CR> if ready.

        Input < CR >. An editor starts up, and then the cursor moves to 
        a position just after the error position for your convenience. 
        After correcting the error, you may quit the editor by the ^Y 
        or <SAVE> command (the quit command in the Apollo display manager). 
        Next, input r. that is a subcommand of the sflread command and means 
        "retry." At this point of time, only the following three commands 
        are available;

            r. : retry
            a. : abort
            h. : help

        If you input a., the sflread command ends. If there is no error 
        in your SFL source file, no message is returned. Because it takes 
        time to implement an sflread command, for your convenience, 
        you should save the inner representation of the SFL module class 
        with the sflsave command after the sflread command ends.

        Also, if you see the following message example during 
        the input of a subcommand of an sflread command:

      prolog: syntax error at LINE=2, COLUMN=0

        Press the < CR > key several times, and thus, 
        after you make sure the input prompt : is displayed, 
        input the subcommand.

    (E) sflread <sflsource> -exp

        Once the sflread command starts its execution with this format,
        you can use memory and operators, both of which are originally 
        available only in function circuits, in every position.
