Introduction of TSO/ISPF

Imagine the confidence and speed which you get, if you master TSO Mainframe Tutorial and ISPF Mainframe Tutorial.

This Tutorial is in-depth and precise TSO/ISPF tutorial on IBM Mainframe.

We will also cover MVS TSO tutorial here.

  • TSO Stands for Time Sharing Option.
  • ISPF Stands for Interactive Search and Display Facility.

What is TSO?

TSO is the short form of Time Sharing Option in which multiple users can access the MVS (Multiple Virtual Storage) concurrently and to each user, it will appear that he or she is the only user in the system.

Each user in the system has an Address Space and a unique user id which is 8 character maximum. Each user has its own profile and logs as well.

Important Functions of TSO

TSO also provides commands to manage datasets. In Mainframe, the files are called as data sets. TSO interacts with either a line by line mode or in a full-screen menu driven mode. There are a lot of functions which TSO can handle. Let us understand all these functions –

  1. Dataset Management Functions like Deletion of data sets, Insertion of records in a dataset or Updating the records in Dataset etc. 
  2. Another important function which TSO can handle is Program Development functions 
    like Creating a program, Compiling the program, Link Editing the program, Executing the program etc.
  3. The next important function is Batch Job Functions like Submitting a job, Monitoring a job and Viewing the output of a job.

What is ISPF?

ISPF is the shorthand for Interactive Search and Display Facility and this is a software that provides the dialog management service and users can directly use the menus to perform the required operations.

The commands that can be used in TSO can be entered via ISPF Panel and this panel has Action Bars, Program Menus Point and Shoot Field, Selection Fields and, Function Keys. 

What is TSO/ISPF

In Line By Line Mode, users enter a command by typing through their keyboard while in Menu Driven Mode, users interact with the Mainframe through ISPF menus. The combination of TSO and ISPF is called TSO/ISPF.
