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.  

The self-extracting file is called either "Bextract.exe" (for Bertie3) or "Textract.exe" (for Twootie.) 


The routine for the typical Windows installation:  

  1. 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"
  2. 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. 
  3. 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. 
  4. When you have your destination directory set, click "Extract".
  5. 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.

  1. 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. 
  2. 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.
  3. 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 asked.
  4. 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:

  1. 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.
  2. 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.
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.
