Installing Bertie3 or Twootie
The installation procedure described here makes the assumption that you are
running some version of Windows from Windows 95 on (including 98, 2000, ME, or
NT). I have not tested this on Windows XP. If you are running
Windows 3.1 please see the note at the bottom.
The code is distributed in self-extracting ZIP files. You do not need
to have your own copy of PKZIP or UNZIP in order to extract the files; once the
self-extracting file is downloaded, you simply double click it, and all the needed files
will extract themselves. If you are running an operating system in which the
self-extracting zip file does not work, please send me an email, and I can point
you to other distribution packets that might work.
self-extracting file is called either "Bextract.exe" (for
Bertie3) or "Textract.exe" (for Twootie.)
The routine for the typical Windows installation:
When you go back to the Bertie/Twootie home page, click on the "download the software" link.
A windows will pop
up and say something like "You have a chosen to download a file from this
location... What do you want to do with this file?" It will
name either "Bextract.exe" or "Textract.exe". Click the
box that says "Save ... to disk"
Another window will pop up with the label "Save as..." It allows you
to specify the directory where you want to put the self-extracting file. Pick
any location that you can find later. Click "continue"
and you should get a "download complete" message in relatively short
order. If your download is interrupted the file might be terminated
prematurely; in that case just try downloading the file again.
The next step is to make the self-extracting file do its business. First find the place where you put
the downloaded file (Bextract.exe or Textract.exe).
Double click on the file name. A window will pop up with a label that
starts "PKSFX for Windows" and a box that says "Extract
to...". That destination directory is the place where the extracted
files will be placed; where Bertie3 or
Twootie and all their files will be found. The window gives a default
destination (typically "C:/windows/temp")
but you can change it to whatever you want by using the Browse
button. It's perfectly OK to extract the files into the same
directory into which Bextract.exe or Textract.exe was placed.
- When you have your destination directory set, click "Extract".
You should get a confirmation message that says "Extraction
completed". Click OK. (If you do not get this confirmation
message, just try the steps up to this point all over again. A single
hiccup in the download process can make this fail, and so sometimes you have
to try a second time.)
Now to start Bertie3 or Twootie. Go look at your "destination" directory--the one into which the
files were extracted.
- The stored problem sets are the "*.ber" files (for
Bertie3) or "*.two" files (for Twootie). The text files
are all "*.txt". The executable program is Bertie3.exe
or Twootie.exe respectively.
- If you are using anything from Windows 95 on, you can start the program by
simply double clicking on that file name. The program will start a
DOS window, with a default window size of 25 lines, and with a default font of
10 x 20. The big buttons up at the top of the DOS window can
be used to change these defaults. (Both programs support a screen size
of up to 50 lines, and if you switch to that screen size you will want to
adjust the font size.) Another default: the DOS window will close
automatically when you quit Bertie3 or Twootie.
- You can change the defaults by right clicking on the name of the executable
file, and adjusting the various parameters you find. It is also easy to create
such a shortcut by opening "Windows Explorer", finding
the executable file (Bertie3.exe or Twootie.exe), clicking on
it and holding down the right mouse button, dragging to the desktop,
letting go, and selecting "Create Shortcut here" when
- Both programs start by reading a configuration file in which defaults for
program behavior are set. These are bconfig.ber for Bertie3 and
tconfig.two for Twootie respectively. Those files can be edited with
Edit, Notepad, or Wordpad, and defaults changed as you like. See the
Help system for details.
If you are using Windows 3.x:
Once installed, many of the defaults and options in the programs
can be reconfigured to suit your own needs and preferences. For
example, they can be reconfigured to use different characters
for the logical symbols. You can re-define the characters the
program uses to print logic symbols. You can change some of the
syntax defaults and options for providing hints. For more details
see the "reconfiguration" topic in the help system.
- A "Program
Information File" or "Pif" file is provided which can help set
up. It has a default assumption though of the destination directory into
which you will extract the extracted files. That default is
C:\logic. A directory with that name can be created in
various ways, including use of the DOS command md (make
directory) and cd (change directory). The default location
is important only if you are using Windows 3.x: the "Program
Information File" or "Pif" file that is provided
assumes that the program will be found in C:\logic. The
"Pif" file tells Windows 3.x how much memory to reserve
and where to find the executable file. If you want to use some
other directory for the program under Windows 3.x, you can, but
you will need to use the Windows PIF editor (in "Main")
to edit the "Pif" file provided.
- You can create a shortcut using
the supplied "PIF" file. Under Program Manager select
File, New, and then New Program Item. You will then be prompted
for Program Item Properties. Assume you have installed the files
in the directory "C:\logic". For Bertie3 you want the
Description to be "Bertie3", the Command Line
to be "C:\logic\bertie3.pif", and the Working
Directory to be "C:\logic". For Twootie you want
the Description to be "Twootie", the Command
Line to be "C:\logic\twootie.pif", and the Working
Directory to be "C:\logic". Shortcut Key can
be left empty in both cases. Click "OK" and you should
find a new icon. If you install the program in some directory
other than "C:\logic", and are running Windows 3.x,
you will need to edit the Pif file, as noted above.
