Workspace Combo Box
The Workspace combo box is provided for you to instruct the compiler which workspace to use when compiling. The compiler starts up in the most recently used workspace in the Studio. You can scroll and select earlier entries from this combo box.
You may select one of the recent workspaces or Defaults, or you can click the prompt button to the right, which will allow you to browse to the Studio workspace (.SWS) file. What you select will adjust the contents of the Paths and Options tab pages according to values recorded in the workspace you select.
