LOGOFF command

Use the LOGOFF command to terminate your terminal session. When you enter the LOGOFF command, the system frees all the data sets allocated to you. Data remaining in storage is lost.

If you intend to enter the LOGON command immediately to begin a new session using different attributes, you are not required to LOGOFF. Instead, you can just enter the LOGON command as you need to enter any other command.

If your terminal is a Systems Network Architecture (SNA) terminal that uses VTAM®, you might be required to use a format different from the one described here. Your system programmer should provide you with this information.

When the LOGOFF command is executed in the background, your TSO/E session is terminated normally. Any remaining commands in the input stream are ignored.

The TSO segment, which includes the TSO profile, will only be written to the RACF® database if it has changed during the TSO/E session where the user is issuing LOGOFF.
