About Mainframe:

A mainframe is a large-capacity computer system with processing power that is significantly superior to PCs or midrange computers. Traditionally, mainframes have been associated with centralized, rather than distributed, computing environments.

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.

Any business application is divided into logical modules and these modules are developed using programming languages. These programs should be executed in a pre-defined sequence to achieve the business functionality.

JCL (Job Control Language) is used to DEFINE and CONTROL the JOB to the operating system.

COBOL:

First language developed for commercial application development, which can

efficiently handle millions of data.

2. Procedure Oriented Language – Problem is segmented into several tasks.

Each task is written as a Paragraph in Procedure Division and executed in a

logical sequence as mentioned.

3. English Like language – Easy to learn, code and maintain.
