This parameter specifies whether or not you want automatic formatting of Control Structures in functions. The default value is 1 which means that formatting is done automatically for you when a function is opened for editing or converted to text by ⎕CR, ⎕NR and ⎕VR. Automatic formatting first discards all leading spaces in the function body. It then prefixes all lines with a single space except those beginning with a label or a comment symbol (this has the effect of making labels and comments stand out). The third step is to indent Control Structures. The size of the indent depends upon the TabStops parameter. To turn off automatic formatting, set AutoFormat to 0.
