stdio

    Accompanying Frotz is FrotzStdIO, a version of Frotz which uses only
    standard input and output (i.e. a shell window). This allows Frotz to take
    input from a file, or to be used over a network. In the latter case, the
    output terminal must support ANSI 3.64 character sequences.

    FrotzStdIO can only be run from the shell, and its operation controlled only
    by command line switches. In addition to the switches available in Frotz,
    the following extra switches are available:

    	-f	Sets the foreground pen to be used for all text. The
    		default is 1 (which is usually what the shell uses, and
    		is usually black).

    	-w	Sets the screen width in characters. FrotzStdIO cannot
    		determine the screen dimensions for any given output
    		(Indeed, if the output stream is a file, there is no
    		concept of a screen.), so this and the following switch
    		must be used to obtain the required display size. The
    		default is 77.

    	-h	Sets the screen height in characters. The default is 21.

    	-C	Normally CTRL-C will exit FrotzStdIO. If this switch is
    		used, the CTRL-C signal is ignored.

    	-T	This switch limits the length of time for a game session.
    		If specified it must be followed by the maximum number of
    		minutes the session may last. Warnings are issued at 5
    		minutes and 1 minute before the time limit expires.

    	-V	This switch can be used to limit the input and output
    		capabilities of FrotzStdIO. Whatever text follows the
    		switch will be used for saving and restoring games, e.g.

    			-Vusername.save

    		and all other file operations will be disabled. If the
    		filename contains a question mark, e.g.

    			-Vuser?.save

    		then up to 10 save files may be used. When the game is
    		saved or restored, the user is prompted for a number
    		which replaces the question mark to give the saved game
    		name.
