Downloading and running the executable hat.exe Create a new folder in a location you can find easily, called CryptoPrograms or something similar that you will easily recognize. Create another folder inside this one entitled Hat. Now download the executable hat.exe into the Hat folder, as well as the word list that you will be using. I used the English-PHOENIX dictionary found in the resources section of the ACA website, and renamed it Phoenix.dict. Its size is approximately 3.1 Mb. To run the program, double-click the executable, and a new window should open. It will ask for the number of letters in the word. Before going further, I suggest that you customize the window as follows: 1. There is an icon just to the left of the title at the top left of the window. Clicking on this reveals a drop-down menu. Select the Defaults option. This opens another window called Console Windows Properties, which has 4 tabs. Change nothing in the General tab. 2. Click on the Font tab and choose Lucida Console, whose letters are easy to read than the other choice. 3. Click on the Layout tab. Increase both the window width and screen buffer width from 80 to 100, giving a slightly wider window. 4. Click on the Colors tab. Change the screen background from black to white and the screen text from white to black by clicking on the appropriate radio button and then on the desired color square. 5. When you have finished making the changes, click OK. These changes don't take effect until after the window is closed and re-opened. To make the changes immediate, select Properties in the drop-down menu and make the same changes. You can make the window longer by dragging down on the lower right corner of the window. At the correct mouse position, a double-headed arrow control should appear. You can't make the window wider using this control. After customizing the window, go back to the program window, and enter the number of letters. The program then asks you to enter the order numbers, one at a time, followed by the Enter key. After you have entered all the numbers, the program asks for the name of the word list. Then it will list any words it found whose order numbers match the order numbers you entered, followed by the total number of words of the correct length it found in the word list. The program then tells you to press the Enter key when you want to quit. If at some point you want to print out the display, you will need to prepare the window to highlight the part you want to print. To do this, follow these steps: 1. Click on the icon at the top left corner of the window and mouse down to Edit. 2. A second menu opens; select Mark. 3. Now use the mouse to highlight the portion of the window you want to print. This is done by selecting the area you want just as in a word-processing document. 4. Open the drop-down menu again, mouse down to Edit, and select Copy in the second menu. 5. Open a new document in Notepad or text editor of your choice (I use Notepad++, because Notepad is so bare bones. Notepad++ is a vast improvement, and it is free). 6. In the document's Edit menu select Paste. The part of the window you highlighted should now appear in this document, and you can print it.
