Thanks for refresher videos , these videos are used to revise our-self before any interviews. Can you please do for the special tools that are recently used in mainframe. or the other existing utilities like Expeditor, Version control tools like Changeman, then the scheduler CA7, File-Aid.. If you do videos for the tools it would be really helpful for those who had a gap in career and want to refresh. thanks in advance!

If we are defining a data item with sign symbol, for eg: s9(05) . Will it take positive sign or negative sign ? what is the default sign ?

[@sarathpelluri9621]

positive

[@KumarITChannel]

The default would be positive. If you want to change it to negative you can move or pass the value. 01 WS-SIGN-NEG-NUM PIC S9(3)V9(2) VALUE -123.45.

[@rty1955]

As a programmer of one of the largest, non stoppable ATM network, we NEVER used COBOL for the Network. It was all proprietary assembler code😊

pls explain difference between next nd continue

[@KumarITChannel]

In COBOL, "NEXT" is used to transfer control to the next iteration of a loop, while "CONTINUE" is used to do nothing and continue with the next statement.

You need to have the emulator installed on your system. Search for tn3270 emulator after the installation you can connect to mainframe.

[@Dev-iu2gs]

@@sanjeevnaruboina215 Check for IBM ZOWE an open source mainframe simulator tool, you can get a month trial wherein you would be able to connect to MVS where you can practice JCL/COBOL programs, i didn't try DB2, but I am sure there would be necessary provision for that as well.

Why are we talking abput Cobol when its monopolized by IBM and Micro Focus. Where is version that is Web Stack ready??? I could do a better job with PHP than Cobol now. IBM (Its Big Mess) is holding so that their mainframes will still survive. $hit!

[@KumarITChannel]

I hope you find this useful. It's evident that you have strong feelings about COBOL and the way it's being managed by its major vendors. Indeed, COBOL has been a significant player in the IT industry for decades, particularly in mainframe environments. Let's unpack some of the points you've made: COBOL's Relevance: COBOL remains relevant because many critical systems, especially in the banking and financial sectors, still run on it. It's not so much about the superiority of the language itself but about the decades of legacy code that institutions find challenging to migrate. IBM and Micro Focus: While IBM and Micro Focus are major players in the COBOL world, especially in terms of compilers and platforms, they're not the only options available. However, their solutions are among the most mature and widely adopted in enterprise environments. Web Stack & Modernization: There have been efforts to make COBOL more "web-friendly". For example, Micro Focus offers solutions to expose COBOL applications as web services. There are also frameworks that allow integration of COBOL with modern technologies. But you're right in the sense that it doesn't compare to modern web-centric languages or frameworks in terms of ease of development or ecosystem. PHP vs COBOL: PHP and COBOL serve very different purposes. While COBOL is rooted in business logic, often for large, monolithic applications, PHP is a server-side scripting language tailored for web development. The two aren't directly comparable. However, with the right tools, you can integrate COBOL logic with a web front-end developed in PHP or another modern language. Legacy and Migration: One significant challenge for many organizations is that migrating from legacy COBOL applications to more modern platforms is expensive, risky, and time-consuming. COBOL's persistence isn't just about companies refusing to adopt newer technologies, but often about risk mitigation and financial pragmatism.

@@KumarITChannel I have been a Cobol programmer on the IBM and NCR Mainframes as well IBM S/36/38s. COBOL is the best language i know I can do wonders with it. Now that i have matured and grown into the world of Internet and Web Technologies, i am deeply disappointed because COBOL i still lagging. Why? IBM monopoly. I hate them since 1973. I know PHP is in a different domain but COBOL should have been there if not for 2 big bullies - IBM and Microfocus. Leaving these aside, can i ask you a favor to recommend some solution for COBOL on the Windows platform that can integrate with web techs run on both linux and windows? Or are you arms twisted by the bullies?

[@rino19ny]

that's read as 3 trillion dollars!! NOT "dollar 3 trillion"!!

[@rty1955]

I can assure you, if you use DISPLAY or ACCEPT clauses on a mainframe, or you will be looking for another job. What this does is send/receive from the operators console. NEVER do this. Instead use parameters at run time. Also you vide iis geared to VS (MVS, O/S, ETC) Therr are other operating systems on the mainframe. You onviously were spoon fed on MVS I used to teach COBOL debugging for a large university. You need to be VERY careful of numeric input variables as it does NOT perform type checking. Therefore it IS possible to perform math with alpha characters. I have demo'd this to my students. Also there are different verions of COBOL as well. For examole COBOL-D does NOT have a perform clause.

[@chandranshpandey1929]

Mja nhi aayi

[@djd829]

16:54 shouldn't this be DISPLAY WS-GROUP2. ? We already know the values of WS-GROUP1, we want to prove that the move worked.
