Besides the Windows commands for closing, opening, and sizing windows, the Development Environment has commands for displaying and arranging windows. These commands appear on the Window menu and include:
| Command | Action |
| Cascade | Overlaps all open windows. The top of each window appears below the previous window's title bar. The active window appears at the front. See Figure 1.3. |
| Tile | Resizes windows so that all open windows appear on the screen without overlapping. See Figure 1.4. |
Graphical Development Environment windows support the standard Windows Control menu commands, including the Minimize command. When a window is minimized, an icon representing the window appears at the bottom of the main environment window (see Figure 1.5). Double-click the icon to restore the window.
