What are the three methods of entering TSO commands?

You can enter most TSO commands, CLISTs, and REXX EXECs from all three panel types: data entry; menu; and scrollable data display. However, some TSO commands, such as LOGON and LOGOFF, can cause unwanted results when you enter them from ISPF. This is also true of CLISTs and REXX EXECs that contain these TSO commands.

What is TSO command in mainframe?

Time Sharing Option/Extensions (TSO/E) allows users to create an interactive session with the z/OS® system. TSO provides a single-user logon capability and a basic command prompt interface to z/OS. Most users work with TSO through its menu-driven interface, Interactive System Productivity Facility (ISPF).

How do you execute TSO commands in REXX?

To start a TSO session in order to run a CLIST or REXX exec:

1. Select the CLIST or REXX exec file on the Files view.
2. Click Start Debugging or Run on the Debug menu.
3. Click the TSO tab; the Clist or REXX exec to execute field contains the name of the file that you selected.
4. Click OK.

What is ISPF command?

This is a list of the various commands that can be entered into the field alongside the individual lines of the file that you are editing using the ISPF editor. These commands usually act on the data line that is alongside and may also affect adjacent lines if a number is typed alongside.

What best describes difference between TSO and ISPF?

TSO provides a single-user logon capability and a basic command prompt interface to z/OS. What is ISPF? ISPF is a full panel application navigated by keyboard. ISPF includes a text editor and browser, and functions for locating and listing files and performing other utility functions.

Can we automate mainframe using Python?

We will use a Python script that will issue several Brightside commands to start the required started tasks. This script can be executed in any system where CA Brightside and Python are installed. Before running the real test on Jenkins, we will run the script locally on the workstation to make sure that it works.

Can we automate mainframe using selenium?

It’s no wonder that mainframe testers also ask if Selenium can be used to test their mainframe applications. Unfortunately, the short answer to this question is no; you cannot use Selenium to automate your mainframe tests, simply because Selenium only works in the browser, and not on mainframe applications.
