Window Updates System Debug automatically updates all displayed window values after the completion of every interactive user command list. In addition, when the user single steps (SS) the program, or continues (C) program execution until the next breakpoint is encountered, System Debug automatically updates the windows. System Debug knows the current value of each cell in each window on the screen, and is therefore able to efficiently update only those cells that have changed since the last update. Consequently, window updates are very quick and are not distracting to the user. When major changes appear during window updates, these usually reflect a major change in the program environment, such as a procedure call. Values that have been modified between updates are automatically flagged by System Debug by highlighting them in inverse video. This allows simple visual recognition of cells that are changing. The top of stack area displayed in the frame and stack windows is typically very dynamic. The user can configure the terminal enhancement used to display these changing values (refer to the ENV CHANGES command.) In addition, the user can configure the terminal enhancement used to display the current stack marker (refer to the ENV MARKER command.)
