  This section provides illustrations of the primary windows with explanations of the pull-down menu options on their menu bars. The discussions include:

  - "VPE Window Menu Bar"
  - "Control Panel Menu Bar"
  - "Image Window Menu Bar"
  - "Colormap Menu Bar"
  - "Menu Bar Menu Bar"
  - "Message Window Menu Bar"
  The Sequencer and Help primary windows have no pull-down options, so they are not discussed here. See "Using the Sequencer" for information about the Sequencer, and 5.3 , "Using Online Help" for information on the Help window and Help menu options.

  ### VPE Window Menu Bar

  The menu bar displays the titles of seven menus:

  - File
  - Edit
  - Execute
  - Windows
  - Connection
  - Options
  - Help.
  The following sections describe the menus and their options. For many of the menu options, one or more tools on the canvas must be selected in order for the option to be applied. If a menu option is grayed out, it is unavailable and cannot be selected.

  #### VPE File Menu

  The `File` menu displays the options you can use to create new programs, view or edit previously created programs, load macros, and save programs. You must have write permission for a file to save changes directly to that file.

  The following options appear on the `File` menu:

  New | Initializes the VPE for a new program and clears the canvas. If you have opened Control Panels and Image windows from the VPE, they are closed. If a program you changed but did not save currently exists on the canvas, a dialog box appears so you can save changes. If you opened the VPE using `Open Macro` or `Open Visual Program Editor`, this option is grayed out.
  Open Program... | Opens an existing visual program. A dialog box appears for you to specify the desired program name. If a program you changed but did not save currently exists on the canvas, a dialog box appears asking if you want to save changes. If you opened the VPE using `Open Macro`, this option is grayed out. See "File Selection Dialog Boxes" for more information.
  Recent Programs | Brings up a cascade menu with the recently opened visual programs. Select one of the choices to open the respective network.
  Save Program | Saves the current visual program, and associated Control Panels. This option saves the following files: filename`.net` (for network; that is, a Data Explorer visual program); filename`.cfg` (for configuration).
  Save Program As... | Saves the current visual program and all associated Control Panels under a name you type into the dialog box. This option saves the following files: filename`.net` (for network; that is, a Data Explorer visual program), filename`.cfg` (for configuration).
  Program Settings | Brings up a cascade menu with two choices: `Save As` saves the current settings for the visual program (e.g., window placement, interaction mode, camera viewpoint, interactor setup, etc. The settings are saved in a `.cfg` file. `Load` loads previously saved settings from a `.cfg` file.
  Load Macro... | Loads a macro and makes it available in a tools palette. A file selection dialog box appears for you to specify the desired macro file name. See also "Loading Macros"
  Load Module Definition(s)... | Loads a module definition and makes it available in a tool palette. A file selection dialog box appears for you to specify the desired module file name. The executable you are using must either include this module, or this module definition must refer to an outboard or run-time loadable module. See 9.2 , "Loading and Using Outboard and Runtime-Loadable Modules".
  Print Program... | Prints or saves to a file a representation of a visual program. If the `Label Set Input` toggle button is activated, then any parameter value(s) set in the configuration module's Configuration dialog box will also be printed next to the corresponding tab(s), if scale allows.
  Quit or Close | Closes all windows created from the current VPE window. If you have made changes since the last save, a dialog box appears so you can save changes. If you opened the VPE from the Image window or with the `Open Macro` option, `Close` appears as an option instead of `Quit`. `Quit` is grayed out if the `Execute` menu title is highlighted. You must select the `End Execution` option in the `Execute` pull-down menu; or if the Sequencer is running, you must stop it or pause before quitting.

  #### VPE Edit Menu

  The `Edit` menu lists options for manipulating tools on the canvas.

  #### VPE Execute Menu

  You can use the `Execute` menu to execute the current visual program in various ways. This menu is the same as the `Execute` menus in control panels, the Image window, the Colormap Editor, and the Message window. The options in the `Execute` pull-down menu are grayed out when there is no connection to the server.

  The Execute menu lists the following options:

  Execute Once | Causes the visual program to execute only once, using current values and configuration settings. Subsequent interactor value changes do not cause program reevaluation until this command is reexecuted. This option is grayed out if the Sequencer is running.
  Execute on Change | Causes the visual program to execute each time a value or configuration setting is changed. If you are changing values faster than Data Explorer can generate images, the program executes as fast as possible, always using the current settings at the time an execution cycle begins. This option is grayed out if the Sequencer is running.
  End Execution | Causes the visual program to stop executing.
  Sequencer | Causes the Sequencer to display. This option is grayed out if there is no Sequencer in the visual program. While the Sequencer is running, you can change interactors, and those changes are reflected in subsequent frames. You can pause the Sequencer on a particular frame and explore that frame using the `Execute Once` and `Execute on Change` options. "Using the Sequencer" discusses the Sequencer in detail.

  While the visual program is executing, the `Execute` label in the menu bar is highlighted and remains so until execution is completed. If `Execute on Change` is selected, the `Execute` label in the menu bar is highlighted with one color during execution, and another color the rest of the time.

  For more information, see 5.4 , "Executing a Visual Program".

  #### VPE Windows Menu

  The `Windows` menu allows a user to open and create control panels, open previously defined macros included in the visual program, open the Image window, and open the Colormap Editor.

  These options appear on the `Windows` menu:
