If there are many errors and warnings, these files that log the errors and warnings can become very large, especially the MESSAGE.DAT file. It’s a good idea to periodically review the warnings and errors to see if there are any changes you can make to remove them. The fewer messages the system has to process, the better the performance.
You can also change your INI settings to turn off some of the system’s logging features. This will also improve performance—just make sure you have evaluated the messages first. For example you can make the following changes in the Control control group:
LogTransactions = No (eliminates the LOGFILE.DAT file)
LogToConsole = No (eliminates messages which appear on the screen)
These INI options default to Yes.
The system always creates the MESSAGE.DAT file and deletes it automatically each time you run the GenTrn program. The GenData and the GenPrint programs append errors and warnings to the file. So it gets larger and larger if you do not run the GenTrn program as often or if you do not remove the file between runs. For the best performance, evaluate the errors and warnings to see if there are any changes you need to make in the files, then purge the MESSAGE.DAT file and go for a clean run, beginning with the GenTrn program.
