(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.
