In addition to the Tab(-10,1) (Set Minimized Window Title)and Tab(-10,2) (Set Normal Window Title) commands, which work only under Windows, you can use the SET TITLE command under any A-Shell platform to define variable text which dynamically updates the title bar when any of the control variables specified in the title definition change. Under non-Windows platforms, it requires ZTERM or ATE in order to actually write to the title bar of the terminal emulator. See SET.LIT in the A-Shell Command Reference.
