- FrotzS5 V1.6 - an interpreter for all Infocom games. Complies with standard
- 1.0 of Graham Nelson's specification. Written by Stefan Jokisch in 1995-7 for Dos
- and ported to the Psion Series 5 by FrΘdΘric Bouvry (C) Copyright 1997-1999.
- Additional work and bug fixes by Simon Quinn.
-
- This port of Frotz is freeware, that means:
- -You may not make money with this software by selling it or by any other way.
- -If you want to put this software on a CD-Rom compilation, email me before
- to get my agreement. It shouldn't be a problem if you don't charge too much
- money for the compilation, go to http://www.palmtime.com/frotzs5.html for
- contact information.
- -You may not modify the original files.
- -I'm not responsible for any damage this program could cause to your palmtop
- or yourself.
- -But you can play for free and copy it for friends as long as you copy all
- the files included in this distribution.
-
- A good place to get stories is ftp://ftp.gmd.de/if-archive/games/infocom/
- All the stories there ending with .z1 up to .z8 work. Some .z6 games, which rely
- on graphics, may not work. Also Infocom sometimes use .zip extensions for their
- z6 games, these work fine with Frotz.
- Another way to get stories is to buy compilation CD-Roms like
- 'The Masterpieces of Infocom': about 21$US for more than 30 stories +
- the original documentations and maps in Adobe Acrobat .pdf format
- (Activision who bought Infocom is still selling those compilations).
-
- Version Information
- -------------------
- -Official FrotzS5 App UID is 0x1000055B
- -Since v1.1 different font sizes can be selected and the toolbar can
- be turned on/off thus the screen width may be less than 80 columns.
- ! The majority of the stories asks to Frotz what's the current number
- of columns then handles this correctly (or just responds 'screen to narrow'
- but this happens rarely). A few stories (well, I know only one:
- A Mind Forever Voyaging) don't handle correctly a screen width under about 70
- columns so you should switch to e.g. mode 70x18 (without toolbar) for AMFV.
- Dynamic font change during a game is currently not possible. Use 'Terminate Story'
- or type 'quit' to change the font size between stories.
- The internal random numbers generator has been improved since v1.1
- ! Some games record the screen width in their private memory space and
- this memory space is saved since your first 'save' operation (e.g.: The HitchHiker's
- Guide To The Galaxy) so you better select you favourite font/screen/toolbar size
- from the beginning or you may get problems with the title when changing the screen
- size and restoring a game started with a different screen size.
- Some games such as Sherlock use the Invisiclues and assume a screen height
- greater than the current one... same problem as AMFV (see above).
-
- -Since v1.2 you can put your stories and saved files anywhere. Frotz
- will record in his profile the latest place where you read a story
- and the place where you put the saved games. It works even on
- drive D: (Compact card). For owner of previous versions, you don't have to
- but you can move your C:\Frotz directory anywhere now. After the
- first 'Open Story', browse to your new folder where you moved your stories
- open one and Frotz will remember where they are for the next Open. The same
- applies for the save/restore operations.
-
- -Since v1.3 Frotz uses all the screen height of a Geofox palmtop.
-
- -Since v1.4 Frotz should now work on any sized screen, such as Revo
- and Psion7. No toolbar is available on the Revo due to the size of the
- screen. Changed by Simon Quinn
-
- -Since v1.5 Memory usage decreased by 2/3. To do this the number of Frotz undo
- buffers was reduced from 25 to 2, saving 900Kbytes! Rewrote screen display
- code for big performance boost. Cursor keys now work in Journey & Beyond
- Zork. Fixed key timer problem that was causing Arthur to crash. Fixed border
- graphics in Beyond Zork etc. Toolbar buttons tidied up for larger
- screens. Changed by Simon Quinn
-
- -Since v1.6 More speed ups for the screen display code. Fixed major Frotz engine bug
- when printing inverse text blocks that are taller than the screen, such as
- in Sherlock. Squashed a few small bugs. Changed by Simon Quinn.
-
- Install procedure:
- ------------------
- The easiest and best installation is to use the Frotz SIS package. Otherwise
- do the following:
-
- The 4 distributed files are FROTZS5.APP, FROZS5.AIF, FROTZS5.RSC and FROTZS5.TXT
-
- 1) Make sure you can see the System folder on the Psion by using the check box
- in the System menu -> Tools -> Preferences -> Show 'System' folder.
- 2) Create a new folder called 'FrotzS5' under C:\System\Apps thus C:\System\Apps\FrotzS5
- 3) Copy all the files from the distribution to this folder with PsiWin.
- 4) Create the folders where you will place the stories and save your games.
- e.g.: C:\Documents\Frotz\Story, C:\Documents\Frotz\Save (or even on drive D:)
- 5) Put the story files you want to play in the folder you created for them.
- e.g.: C:\Documents\Frotz\Story
- 6) Now you should see the FrotzS5 Icon in the Extra Toolbar.
- 7) The first time you open a story, save a game or restore a game, you will have
- to browse to the folder you created but after that, Frotz will remember them.
-
- N.B.: The application can run on a CF card too, e.g.: D:\System\Apps\FrotzS5

- Thanks to Stefan Jokisch, the author of Frotz, for giving his sources (Dos Frotz v2.32).
- Without him I wouldn't have made this port.
- Special Thanks to Ian Dean, the porter of Frotz to the WinCE palmtops (FrotzCE),
- for helping me to solve a difficult problem that you should better know when porting Frotz...
- Thanks to Steve Richardson for his support and bug reports.
- Thanks to David Isherwood for making the runtime help file of FrotzS5 (not yet included).
- Thanks to Adam Jackson for beta testing v1.2
-
- Supports all games from V1 to V8. Many V6 graphical games work in text mode, such
- as Journey, Arthur and Shogun.
-
- Limitations in current version:
- No graphics, no sound.
-
- Known bugs:
- None
-
- Troubles:
- -Most games need between 300 and 600 Kbytes of RAM so if one doesn't start it is
- possible you don't have enough free memory.

- Documentation from Stefan Jokisch adapted to the Psion Series 5:
- ----------------------------------------------------------------
-
- FROTZ V2.32 - an interpreter for all Infocom games. Complies with standard
- 1.0 of Graham Nelson's specification. Written by Stefan Jokisch in 1995-7
- This program once started as a re-make of Mark Howell's Zip, but
- has grown into an utterly new interpreter.
-
- Frotz is freeware: It may be used and distributed freely provided
- no commercial profit is involved. (c) 1995-1997 Stefan Jokisch.
-
- Special keys:
-
- Ctrl-D - toggle debugging options
- Ctrl-S - help on hot keys
- Ctrl-N - new game (restart)
- Ctrl-P - turn on input line playback
- Ctrl-R - toggle input line recording on/off
- Ctrl-U - multiple undo, works even for old V1 to V4 games
- Ctrl-X - exit game
-
- Psion Shortcuts are displayed in the menu of FrotzS5 like e.g.:
- Ctrl-E - exit from FrotzS5
-
- Other keys:
- cursor left - move one character to the left
- cursor right - move one character to the right
- arrow left - move one word to the left
- arrow right - move one word to the right
- home - move to beginning of line
- end - move to end of line
- backspace - delete character to the left
- shift-delete - delete character below cursor
- escape - delete whole input line
- cursor up - get previous command
- cursor down - get next command
- tab - word completion (like "tcsh" under Unix)
- e.g.: 'exa' then TAB displays 'examine'
-
- When you need to type an unpleasantly long word, try to type the
- first three or four letters then press the tabulator key. If you
- are lucky, Frotz fills in some or all of the missing letters. A
- high beep noise indicates that the word is ambiguous; a low beep
- indicates that it does not exist. Apart from that, you can also
- use the history feature to get to previous input lines. Type the
- beginning of the input line you are looking for, then use cursor
- up/down to scroll through all input lines matching that prefix.
- e.g: type 'lo' then arrow up/down to retrieve all the commands
- that you entered that begin with the letters 'lo'.
- Note: No beep in the Psion Series 5 version.
-
- Questions and answers:
-
- Q: What is Frotz?
- A: Frotz runs text adventures which come in so-called story files:
- ZORK1.DAT, TRINITY.DAT, CURSES.Z5, JIGSAW.Z8, ARTHUR.ZIP etc.
-
- Q: Where can I find story files to use with Frotz?
- A: First, you can use the files from your original Infocom games. It
- is possible to play Atari ST, Amiga or Macintosh games on your PC
- once you manage to transfer the story files. Some people even
- extracted story files from old Atari 800, Apple II and C-64 disks
- (ask your local 8bit guru). Second, there is an increasing number
- of new games available on the Internet. Check the if-archive at
- ftp.gmd.de.
-
- Q: Why does Frotz stop with an error message?
- A: It might have detected a bug in the story file other interpreters
- overlooked. It's also possible that the story file is corrupt;
- be sure to download story files in binary mode, especially when you
- use a WWW browser.
-
-
- List of fatal errors:
-
- - "Bad stack frame"
- - "Byte swapped story file"
