VLISP contains its own set of windows and menus that are distinct from the rest of PRODNAME, but VLISP does not run independently of PRODNAME. Whenever you work in VLISP, PRODNAME must also be running. When you run AutoLISP programs from the VLISP IDE, you will usually need to interact with the PRODNAME graphics or Command windows to respond to program prompts.
If PRODNAME is minimized when VLISP turns control over to it, you must manually restore and activate the PRODNAME window to continue. VLISP will not restore the PRODNAME window for you. Instead, a Visual LISP symbol appears in the VLISP window and remains there until you activate PRODNAME and respond to the prompts at the PRODNAME Command prompt. The Getting Started chapter shows an example of this; see Loading and Running AutoLISP Programs.
