To enable users to log on to TSO/E and access system resources, you must write logon procedures, and give users access to them. A logon procedure:

• Specifies the system resources available to the user logging on
• Specifies the number of data sets the user can have dynamically allocated
• Specifies which program is invoked after the user has logged on. The program can be the TSO/E terminal monitor program (TMP), Session Manager, or an installation-written program.
