WINDOW REFRESH

Reprint Entire Screen

This directive causes the entire screen to be redisplayed, as it was last known to the Thoroughbred Basic Windows Manager. It is very useful in situations where a SYSTEM directive may have caused data to be printed on the terminal, a broadcast message from root has disrupted the screen, or the terminal was powered off and then on again. It is sometimes helpful to program a function key or hotkey to cause the application to issue this command.

If this task is configured for Thoroughbred Basic Windows, only the standard set of Thoroughbred Basic terminal mnemonics should be used to send output to the terminal. Using direct hexadecimal escape sequences to control the terminal screen may cause the Thoroughbred Basic Windows Manager to lose knowledge of cursor position and character attributes.
