Really awesome, nice explanation , best refreshing video, thank you so much
Glad it was helpful!
Your videos are so good. before interview, It helps so much. it would be more helpful if you take topic on connecting CICS with web services, showing the source code and what all ulities we used to connect like that, can you put a detail video on that ?
Awesome.Good job.Keep up this good work
you are the god for me..thank you sir
The COBOL/Mainftame content is very useful,. Thank You!
Glad to hear that!
Awesome Kumar , Big Kudo's to you! It really helps even experieced people for interviews.. I am Expecting similar videos for IMSDB/DC
Sure 👍
Very helpful... Best vdo with all the required information about Cobol. Thank you for such a video.
Hi Kumar , thnkuu for ur amazing videos . One request , can we get a video on Xpeditor I couldn’t find this topic in ur channel.

Thank You Vamsi. Happy to hear!!
Thanks Kumar regards from ARgentina!
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!
Thanks Divya. Sure Will try to do some videos on tools.
Thank you, it was amazing
Yes you covered all topics ... tq
Nice Video buddy
Clear explanation sir keep update more
Sir can you do pl1 refresher video with programs your all videos are useful for interview
When will we get the cics refresher video. Your video are a blessing for mainframer's. Please upload CICS video
I have been programming in COBOL for 12 years and didn’t realize it. I thought I was just learning the govt system. We have a super proprietary way of using cobol and assembly so I am seeking the learn a more general structure
BS
Sir, please upload the one video on a sample project please please please 🙏🙏🙏
Thanks bro
You are very helpful
Hi! Thank for your videos! I'd like to suggest you that, if you can add subtitles to your videos! Thanks.

Thanks for the clear explanation sir
Once again many thanks Sir
Always welcome
You're awesome thank you very much for sharing can do more videos that helps us very good thank you so much..🙏🙏
Thank you, I will
Could you add IMS DB for beginners and refreshers video ??
Can you make a refresher video for IMS DB also plese..it will be so nice ... :)
Will be doing in 2021. Thank you!
Thank you so much for your every video :)
what is directory blocks significance while creating PDS ?
Thank you.. Really helpful
Thank you Kumar ! I also would like to see examples of how the COBOL coding is used for the ATM Machines, I want to do study about the ATM programming, can you help please ? Thank you Kumar !
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😊
Can you provide real time problem example so that it is get full info about this tq sir
Great video, please have a similar refresher for DB2.............Please................!!!!!!!
Noted! Thanks! Shiraz
Thank you.. very useful
Thank you kumar sir.
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 ?
positive
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.
Awesome boss
Awesome video
can u share the PPT???
I feel bad for his keyboard though
Very useful!
Thank you so much sir
Well explained!!
Great content !
if you could share this PPT that would be more great !
Please do refresher videos on db2 ims and cics also please
Sure Zareena that's next in my queue.
Happy learning! and thanks for watching.
@@KumarITChannel Waiting for db2 sql.... Thanks for all these refreshers
Thats my first programming language
I dumped it for a much better language - Assembly
Amazing videos... Very helpful ❤️
Can you confirm for this video time 13:30 the part 01 WS-MONTH PIC 9(2) VALUE 05. Its group data name, can we use 01 for that?
Yes you can.
pls explain difference between next nd continue
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.
Can I access both VSAM and DB2 from a the same cobol Cics program?
Can you create based on the scenario interview point?
New Mainframe Trainings Classes going on?
brother Tomarrow i have cobol interview any requried tips brother?
hello what is the difference between right and left justified? 13:45
How is the scope of mainframe for freshers?
As a fresher any technology is good . Mainframes are there from many decades and still we be there for decades..Feel proud to work in mainframe systems..
@@KumarITChannel I worked years on some of the super minicomputers. DEC PDP, DG MV 1000 and 1500. Some others.
Hi, in the redefines explanation, could it be that the ws-date-2 field is missing two 1 byte fillers? one after ws-dd and one after ws-mm
What is the scope of mainframe in current
5:41 "Envy-Ronment"
Hi, any chance to get some examples of analysis and requirements gathering in mainframe? Thank you
Yes, soon! I will be making a video on it.
sample cobol program of student having 5 students id,names,3 subjects marks, calcutate total,avg,precentage,grade pz make vid

I want this notes... where I get it?
I am 55 years old. I have worked in microfocus COBOL on UNIX based machine. I want to update with Mainframe COBOL and looking for job also can you help me?
Hi Aditya, Please drop an email to kumaritchannel@gmail.com.
Hi Aditya
I want this ppt doc can you share plz
Kudos to you bro!, as you're mentioning in the beginning of the video, for the detailed and in depth understanding where can we find the information? Can you please let me know?
Thanks in advance!
Glad it was helpful!.. Please do check out my playlist for more Updates.. Thank you!
Can you please suggest good institute for mainframe courses in Chennai ? With contact numbers
No Idea. You can check for COURSERA or UDEMY or IBM Redbooks for self learning and it's good.
Can u make video on COBOL program analysis
Sure definitely
Nice work, but too fast 😀
Can you please send PC download version link, if possible add to description.
I hope you got the solution from my other Video.. Thank you! for watching.
Bro
Db2 refresher as soon as possible
had an interview
How can we practice jcl in windows?
You need to have the emulator installed on your system. Search for tn3270 emulator after the installation you can connect to mainframe.
@@KumarITChannel after installation what we have to do?
@@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.
I need support for 1 months i will give some amount to cobol
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.
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!
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?
that's read as 3 trillion dollars!! NOT "dollar 3 trillion"!!
:)
Mja nhi aayi
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.
Thank You Kumar. This is very informative tutorial. Please add your picture in the beginning of the videos if possible.
