The FTP server can be configured to display customized messages to the clients when the user changes MVS directories. Two configuration options are available, the MVSINFO Low Level Qualifier (LLQ), the ANONYMOUSMVSINFO Low Level Qualifier (LLQ).
To activate any of these messages, specify the LLQ of the data sets containing the messages in the respective field on the configuration panel. Use of directory change messages is optional. You may specify the same LLQ for both MVSINFO and ANONYMOUSMVSINFO to show the same messages for named users and anonymous users.
