Close All Windows R←2023⌶Y
Under Windows the option, Windows -> Close All Windows allows the user to close all open Editor and Tracer Windows, but does not reset the state indicator.
This I-beam mimics this behaviour, thus allowing the user to write code which can close all windows before attempting to save the workspace; with the exception of calling 0 ⎕SAVE
it is not possible to save a workspace if any editor or tracer windows are open.
Under non-Windows operating systems this is the only mechanism for closing all such windows. This I-beam is effective in RIDE too.
