>Dumb question du jour: Is there a way to programmatically clear the debugger output window, without issuing CLEAR DEBUG? I would like to be able to do the same thing programatically that "clear output window" does from the debugger's Window menu, but without clearing breakpoints and restoring default window sizes and positions like CLEAR DEBUG does.

You mean like Right-Clidk in the Debugout window, then clicking Clear?
