TRACE ON
This statement turns tracing on. This means that if logging is turned on, trace information will be logged into the log file while the script is executing. To turn logging on in the Map Designer, choose Preferences from the View Menu and on the Logging Defaults tab, check Error and Event Logging ON/OFF. In this window, the log file may be set along with the message types to be logged. Since a CXL trace logs debug messages, this message type should be selected under Error Types to Log.
The information logged to the log file during a trace is:
• the first 32 characters of each input line
• an indication for each pattern/action statement of whether the pattern match is successful or not.
