There is a single Console window for all open AutoCAD drawing documents. When you scroll through the Console window, you see commands entered in all document contexts. This differs from the AutoCAD Command window, which shows only the commands issued against the current drawing. In other words, each AutoCAD drawing has its own Command Line window, but all drawings share the same VLISP Console prompt.
VLISP automatically switches context when you change the active drawing document in AutoCAD. The active document in AutoCAD is always the active document in VLISP. Commands entered in the VLISP Console window always apply to the active document. The title bar of the VLISP window contains the name of the active drawing document.
