(3)During log output

When the command execution result is being output to a log file as specified by the log command, the trace data is displayed in the [Command] window and its contents are also output to the log file.

If the [Trace] window is closed, data is displayed in the same way as in (2) above.

If the [Trace] window is open, its contents are redisplayed. In this case, the same number of lines are displayed in the [Command] window as displayed in the [Trace] window.

(4)Successive display

When you execute the td command, the trace data can be displayed successively by entering the [Enter] key only until some other command is executed.

When you input the [Enter] key, the [Trace] window is scrolled forward one screen.

When displaying data in the [Command] window, 11 lines of data preceding the previously displayed cycle are displayed in the [Command] window (the same number of lines as displayed in the [Trace] window if the command is executed during log output).

The direction of display is such that each time you input the [Enter] key, data on older execution cycles is displayed (FORWARD). This direction can be reversed (BACKWARD) by entering the [B] key. To return the display direction to FORWARD, input the [F] key. If the [Trace] window is open, the direction in which the window is scrolled is also changed.
