Break Command (Run Menu)
Stops execution of a program while it's running and switches to break mode If a statement is being executed when you choose this command, that statement is displayed in the Code window with a thin-line border around it, and highlighted in the colors you set with the Environment command on the Options menu. If the application is waiting for events in the idle loop (that is, no statement is being executed), no statement is highlighted until an event occurs..
Some editing changes made during break mode may require you to restart your program for the changes to take effect.
