CICS. Customer Information Control System (CICS®) is a family of mixed language application servers that provide online transaction management and connectivity for applications on IBM Mainframe systems under z/OS and z/VSE.
CICS is middleware designed to support rapid, high-volume online transaction processing. A CICS transaction is a unit of processing initiated by a single request that may affect one or more objects.[1] This processing is usually interactive (screen-oriented), but background transactions are possible. CICS provides services that extend or replace the functions of the operating system and are more efficient than the generalized services in the operating system and simpler for programmers to use, particularly with respect to communication with diverse terminal devices. While CICS has its highest profile among financial institutions such as banks and insurance companies, many Fortune 500 companies are reported to run CICS along with many government entities. History[edit]
CICS - COBOL Basics. CICS programs are written in COBOL language in Mainframes.
We will be discussing about writing a simple COBOL-CICS program, compiling it and then executing it. CICS Program We will be writing a simple COBOL-CICS program which displays some message on CICS output screen. This program is to demonstrate the steps involved in executing a COBOL-CICS program. Following are the steps to code a simple program: Step 1 Login to Mainframes and open a TSO Session. Step 2 Create a new PDS in which we will be coding our program. Step 3 Create a new member inside the PDS and code the following program: IDENTIFICATION DIVISION. Step 4 After coding the program, we need to compile it.
Step 5 Open a CICS session. Step 6 We will now install the program using the following command: Step 7 Execute the program using the associated transaction-id. Why You Should Learn COBOL. Arunn Ramadoss thinks you should learn COBOL.
Admittedly, he's biased. He's the program manager of Micro Focus, a company that sells modernization tools for COBOL (see our previous coverage here). Young programmers may be wondering whether they need to learn Java, or whether knowing JavaScript and either Python or Ruby is enough. And with computer science graduates reportedly receiving multiple job offers straight out of college, why look even further into the past at something like COBOL? According to Gartner, 85% of the world's businesses data was still being processed in COBOL as recently as 2001 (only when discussing something like COBOL could we consider 2001 "recent").
And while many of these applications will be re-written, Ramadoss thinks much of this code will still be around. And even in these days of delayed retirement, many COBOL engineers are leaving the job market. It's not an unreasonable idea. And integration is what will be important for today's students of COBOL. All The Rich Kids Are Into COBOL—But Why? All the cool kids write Node.js.
But the rich kids? They're into COBOL. According to an ITWorld report, college students that take COBOL classes earn as much as $10,000 more in their first jobs than their Go-slumming hipster friends. Even though COBOL is a programming relic of enterprise systems gone by.

Top 10 Reasons to Learn COBOL. Posted on 05.
Feb, 2013 by Scot Nielsen in COBOL, Corporate Social Responsibility, News, Skills A legendary language What is the first thing which springs to mind when you think of COBOL? Did you know that 200 times more transactions are processed daily by COBOL business applications than there are Google and You Tube searches made? COBOL is not about to drop dead – it still dominates the business language world. 1.
