# Changing Options

From the Options dialog, you can change display and interpreter options of Windows Frotz 2002.

Note that when the Z-Machine was designed, computers usually had fixed displays, so little thought was put into allowing the game and interpreter to cope with changes to the screen size, font or colour settings during a game. Windows Frotz 2002 does its best to cope with display option changes, but occasionally it may prove necessary to restart or restore a saved position to get the game to run correctly with changed display options.

## Display Options

Font
The proportional font used for text in the game.

Fixed width font
The fixed-width font used for text in the game that needs a particular layout, such as the status bar, or any maps or symbols the game might display.

Font size
The size, in points, of the fonts used for text in the game. This applies to both the proportional and fixed width fonts.

V6 scaling
The factor used to scale the graphics files for Infocom's V6 games.

Text colour
The default colour for text. Unless the game explicitly chooses a colour, this colour will be used for all text in the game.

Background
The default colour for the background. Unless the game explicitly chooses a colour, this colour will be used for the background.

Fast scrolling
If this option is selected, text is scrolled as fast as possible.

Show [More] prompts
If this option is selected, the interpreter pauses with a [More] prompt after displaying a screen of text.

Left margin
The width, in pixels, of the left display margin.

Right margin
The width, in pixels, of the right display margin.

## Interpreter Options

Interpreter number
The code passed to the game to identify the machine the game is running on. This is used by a few of the later Infocom games to change the appearance of the game. For example, Zork Zero has a black background when the interpreter number is MSDOS but a grey background when it is Amiga, and Journey adds a extra menu to the interpreter window only when the interpreter number is Macintosh.

Report errors
The rule the interpreter follows on encountering an error in the game that is not serious enough for it to have to stop. The choices are:

Never | Never show any messages. All errors are silently ignored.
First time | Show a message the first time the error occurs, and silently ignore it after that.
Always | Always show a message when an error occurs.
Fatal error | Treat all errors as fatal errors. When an error occurs the interpreter will stop.

Ignore runtime errors
If this option is selected, the interpreter will attempt to continue, even if it encounters a serious error in the game. It is recommended that this option not be selected unless you are trying to run a game for which source is not available and the author cannot be contacted.

Expand abbreviations
With their later games, Infocom introduced the shortcut commands g, x and z as synonyms for the commands again, examine and wait, respectively. If this option is selected, the interpreter will expand these shortcuts into the full command, even if the game does not support it. This is useful for playing the older Infocom adventures.

Set the Tandy header flag
This option sets or clears a flag in the game's header that was used by Infocom to indicate a game being sold through the Tandy Corporation. This causes some of the older Infocom games to behave slightly differently. For further information, see

## Startup Options

Set Frotz as the default ...
By default, when Frotz is started, it registers itself with Windows Explorer, so that double clicking on a Z-code file (i.e. a file ending with .z1, .z2, .z3, .z4, .z5, .z6, .z7 or .z8) runs Frotz and opens that file. This can be disabled by unchecking this tick box.

## Text-To-Speech

TTS Voice
This option sets the voice that the text to speech uses.

Rate
This option sets the rate at which the TTS speaks. 0 is default.

Volume
This option sets the volume at which the TTS speaks.
