The Instruction List (IL) editor is an intelligent, free-form text editor for editing Instruction List logic. You can configure the IL editor as to the format and color coding of the IL logic you create, as well as the behavior of the editor itself. Default indentation rules can be applied while editing or you can beautify an entire block with a single command. Contextual smart list support is provided for almost every entry you make, allowing you to choose from a list, labels, variables and instructions when they are expected.

There two basic methods for entering IL logic: Right-click, choose Insert, then choose Variable or Keyword. A smart list appears prompting you to choose a valid item, or create a new item. Start typing and a smart list will appear listing your valid choices depending on where you are typing (Quick-edit method). The IL editor supports cut, copy and paste using the Windows Clipboard, allowing you to interact with other text-based editors such as Notepad. You can drag and drop between the IL editor and other Machine Edition tools, such as the Toolchest and the Variable list. Few restrictions are placed on the way you work in the IL editor.

The editor allows the entry of undefined operands so you can type references to labels or variables that don't yet exist. Any unresolved references are detected upon validation and easily located and corrected.
