Natural system messages are provided in lower case. If your terminals cannot display lower case characters correctly, convert the messages from lower to upper case by executing the program ERRUPPER in the Natural system library SYSERR.

However, once the messages have been converted to upper case, you cannot convert them back to lower case. To recover lower case messages, you have two options:

• Reload the messages by using the Object Handler.

• Unload the lower case messages to a free language code by using the Object Handler before conversion so that a backup always exists. 

For detailed information, see the Object Handler documentation.
