Description

The HIDE WINDOW command is used to temporarily remove, or 'hide', a window or group of windows from the screen. A window is an area of the screen designated for output and input. There is no limit to the number of defined windows. Windows are defined with the DEFINE WINDOW command, and are activated with the ACTIVATE WINDOW command.

The <window-name> is the name of the window as previously specified with the DEFINE WINDOW command. A <window-name list> is a list of window names, each separated by a comma. To hide all currently defined windows, use the ALL keyword.

The HIDE WINDOW command does not deactivate windows. Output may be directed to a hidden window, as long as that window is active. Output to a hidden window remains hidden until the window is revealed with either the SHOW WINDOW or ACTIVATE WINDOW commands.

The HIDE WINDOW command may be used in a hot key procedure to switch the screen display from windows to full screen. Full screen display is enabled with the ACTIVATE SCREEN command. Hot keys enable users, while running an application that is waiting for keyboard input, to press a key to execute a specified procedure.
