I/O Message Levels

Most of the messages that appear in the message frame are those that are determined by the I/O message level. The I/O message is a number that is determined by adding up the codes of the desired message types.

The format of each message is determined by the DBMS connector being used, but the information is similar.

Setting Message Levels

You can set the I/O message level in any of the following ways:
