If you are using the Synergy windowing API or UI Toolkit, the SCREEN command updates the screen and/or windowing system.

The SCREEN command serves as an interface to the windowing API. It enables you to establish small macros (using a combination of the SAVE and @ commands) so you can look at intermediate states of the screen that you wouldn’t ordinarily get to see.

You can place more than one option, separated by spaces and/or commas, on the same line. Specifying WAIT as the last option gives you a chance to examine the current state of the screen before the next debug prompt covers it up.

The following example redraws the windowing system screen, leaves the screen displayed until you enter a character, and then clears the screen before accepting any more debugger commands.
