Introduction to the new mainframeTSO overviewTSO/E Acronym for Time Sharing Option/Extensions (TSO/E) Allows users to create an interactive session with z/OS Provides a single-user logon capability and a basic commandprompt interface to z/OS Most users work with TSO through its menu-driven interface,Interactive System Productivity Facility (ISPF) Copyright IBM Corp., 2006.

Introduction to the new mainframeTSO overview (continued) In a z/OS system, each user gets a user ID and a passwordauthorized for TSO logonlogon. During TSO logon, the system displays the TSO logon screen onthe user’s 3270 display device or TN3270 emulator. z/OS system programmers modify the layout and text of the TSOlogon panel to better suit the needs of the system’s users.

Introduction to the new mainframeUsing TSO commands in native mode Usually, ISPF provides the interface for TSO. However,However TSO includes a limited set of basic commandsindependent of ISPF and other programs. Using TSO in this way is called using TSO in its native mode. When you logon to TSO, the z/OS system responds bydisplaying the READY prompt, and waits for input (similar to aDOS prompt).pp) Copyright IBM Corp., 2006. All rights reserved.8

A CLIST issues the commands in sequence. CLISTs are used for performing routine tasks and working moreefficiently with TSO. TSO users create CLISTs with the CLIST command language.

Introduction to the new mainframez/OS UNIX interactive interfacesLike TSO and ISPF, the z/OS UNIX shell and utilitiesprovide an interactive interface to z/OS.Use the UNIX shell to: InInvokeoke shell scripts and utilitiestilities Write shell scripts (a list of shell commands created with theshell programminggg language)g g ) Run shell scripts and C language programs interactively.

Introduction to the new mainframeInvoking the UNIX shellYou can invoke the UNIX shell in any of these ways: From a 3270 display or a workstation running a 3270 emulator From a TCP/IP-attachedTCP/IP attached terminal,terminal using the rlogin and telnetcommands From TSO by entering the OMVS command or the ISHELLcommand.

Introduction to the new mainframeTSO commands used with z/OS UNIXISHELLÆ This command invokes the ISPF shell. Intended for users more familiar with TSO/ISPF than UNIX Provides panels for working with UNIX files,files mounting andunmounting file systems, and z/OS UNIX administration. z/OS programmers can do much of their work under ISHELL.OMVSÆ This command invokes the z/OS UNIX shell. Intended for users more familiar with UNIX than TSO/ISPF Allows the user to alternate between the shell and TSO UNIX programmers should find the z/OS UNIX shellprogramming environment familiar.

Introduction to the new mainframeSummary TSO allowsllusers tot logonltot z/OS/OS andd use a limitedli it d sett off basicb icommands in native mode. ISPF is a menu-driven interface for user interaction with z/OS. ISPF provides utilities, an editor and ISPF applications to theuser. To the extent permitted by various security controls anISPF user has full access to most z/OS system functions. TSO ISPF should be viewed as a system management interfaceand a development interface for traditional z/OS programming. The z/OS UNIX shell and utilities provide a command interface tothe z/OS UNIX environment. You can access the shell either bylogging on to TSO/E or by using the remote login facilities of( g )TCP/IP (rlogin). If you use TSO/E, a command called OMVS creates a shell foryou. You can work in the shell environment until exiting ortemporarily switching back to the TSO/E environment. Copyright IBM Corp., 2006. All rights reserved.27

In a z/OS system, each user gets a user ID and a password authorized for TSO logonauthorized for TSO logon. During TSO logon, the system displays the TSO logon screen on the user's 3270 display device or TN3270 emulator.
