Parameters and Correlated values are written to the log file if the log level is set appropriately or a special function is used to write the information to the log.

If the logging RunTime settings are set to ''Always write to the log'', ''Extended Mode'' and ''Parameter substitution'', then the parameters and correlated data will be in the log. If, however, the logging is set to only write to the log after an error, or extended mode is not turned on, this information is not available unless special steps are taken to turn logging on, write the data to the log, then reset logging. Logging can be manipulated in the script through use of the lr_get_debut_message and lr_set_debug_message functions.
