  • Logon to z/OS Time Sharing Option, TSO
  • ISPF, Interactive System Productivity Facility, a panel driven TSO application
  • Data Set Names
  • UNIX file directory and file names
  • UNIX shell prompt command processing
  • Edit a Partitioned Data Set member
  • Terminate ISPF session and logoff of TSO

While there are many ways to interact with z/OS, learning 3270 TSO/ISPF accelerates mastery of other web based z/OS interfaces.
