Environment Options
On the Visual LISP Tools menu, the Environment Options submenu allows you to set session-wide VLISP options. For example, you can tell VLISP whether to save text editor files at set intervals automatically, whether to create automatic backup files, and how you want to treat attempts to modify protected symbols. Environment Options is also where you set diagnostic options, such as what statistics to report during syntax checking, and what level of detail to display when inspecting drawing objects. You can also set formatting options for AutoLISP code, and page layout options for printed output.
