Creating an APL Source file

Conceptually, the simplest way to create an APL Source file is with Notepad, although you can use many other tools, for example, Microsoft Visual Studio.

To create an APL Source file using Notepad

1. Start Notepad.
2. Choose Format > Font... from the menu bar and select an appropriate Unicode font that contains APL symbols, such as APL 385 Unicode.
3. Select an APL keyboard by clicking on your keyboard selector in the system tray. This keyboard setting (and button) will only be associated with the current instance of Notepad; if you start another instance of Notepad, or another editor, you will need to select the APL keyboard for it separately and there will be two floating toolbars on your display.
4. Enter your APL code.
   If you use a Ctrl keyboard, you will discover that Ctrl+ keystrokes generate APL symbols For example, Ctrl+n generates ⊤.

5. Choose File > Save in the menu bar.
   The Save As dialog box is displayed

6. In the Save As dialog box, ensure that Save as type: is set to All Files (*) and Encoding: is set to Unicode. Enter the name of the file, adding the extension .asmx or .aspx, and then click Save.

   An .asmx file must be saved somewhere in an IIS virtual directory structure
