start

    From Workbench:

    Frotz can be started with a game file by clicking on the Frotz icon and then
    shift double clicking on the game file icon. Alternatively, if the game
    file's default tool has been set to where Frotz is, double clicking on the
    game file icon will load Frotz and run the game.

    If Frotz is started without a game file, it will search directories chosen
    by the user in the preferences window for valid Infocom games. To speed up
    searching, files are ignored unless their name matches the AmigaDOS pattern
    (~(#?.#?)|#?.(dat#?|z?)). This means that only files with no extension, or
    files ending with .data (Amiga story files) or .dat (IBM PC story files) or
    .zn (where n is a number, these files are produced by the Infocom format
    compiler Inform) are scanned. If Frotz cannot find one of the directories
    specified, the directory will not be searched and no "Please Insert
    Volume..." requester will appear.

    After searching is complete, a list of all the games found will appear.
    Click on the game you want to play and it will load and run. If you click on
    a game while holding down the shift key a requester will appear indicating
    the name of the game, its release and serial numbers, and the full path to
    the game file. At the bottom of this list is a "Select with File Requester"
    gadget. Clicking on this gadget opens a file requester with which you can
    select the game to play. This file requester will also appear if no
    directories have been chosen in preferences, or no games were found. Icons
    for game files can also be dropped on the startup window.

    If Frotz finds the icon Icon.Data, it will give all saved games this icon.

    From the Shell:

    The simplest use is to just pass the full filename of the game file to
    Frotz, i.e.

    	Frotz <game file>

    From the shell the following switches can also be used:

    	-a	watch attribute setting
    	-A	watch attribute testing
    	-c #	context lines
    	-i	ignore runtime errors
    	-l #	left margin
    	-o	watch object movement
    	-O	watch object locating
    	-r #	right margin
    	-R	save/restore in old Frotz format
    	-s #	random number seed value
    	-S #	transscript width
    	-t	set Tandy bit
    	-u #	slots for multiple und
    		(see using Frotz).
    	-x	expand abbreviations g/x/z
    	-W	search for games and show a list of those
    		found as for Workbench startup.
    	-Z #	set error reporting mode, available modes are
    		  0 = no errors are reported
    		  1 = report first occurence of error (default)
    		  2 = report all errors
    		  3 = exit after any error
