Agreed with excitement, but all I can think of is him trying to keep up with a teleprompter. The glare in the glasses sorta give it away IMO. Great info either ways.
In 1972 I was a Computer Consultant with Peat Marwick in London. They sent me on a Cobol course, for at the time I only had Fortran. At the end of the course, they asked the participants what they thought. I stood up and said "I've learnt something very valuable, NEVER EVER TO PROGRAM ANYTHING IN COBOL, IT STINKS." and I never have!
A friend of mine from graduate school back in the 1970s had gotten a BS in chemical engineering at the University of Nebraska. He had to take a programming course in which FORTRAN and COBOL were taught at the same time. He remarked that a single spelling mistake in one COBOL statement could generate pages of error messages.
@@JeffRyman69 It was worse than that. Just try missing out a full-stop! Full-stops were used to teminate statements - like an english sentence. Miss one and everything thereafter, until the next full-stop, was taken as part of the same statement - which compilers found incomprehensible. Remember, back then, there was no such things as interactive debuggers that would highlight syntax errors as soon as they were made. No - we had to bubmit a batch run, usually overnight, So, if you or one of the punch-girls, forgot a full-stop - THAT was another day wasted! FORTRAN had no such problem. Each line of code was limited to 72 characters. That was to leave 8 characters in the end, which was used to gang-punch a numeric code in, so that they could be sorted back into order - in case someone dropped the card deck. AH - THOSE WERE THE DAYS!
Thanks for doing this! COBOL. Learned at uni 40 years ago and worked PT there as an operator. From System 360 to building and training AI models with Watson Studio. 😀
First encountered COBOL at a 3 month COBOL Bootcamp in Johannesburg, South Africa. Enjoyed the college community feel of the bootcamp at Van Zyl & Pritchard (VZAP). Our weekly Friday tests required sitting at your computer and writing code in 7 hour sessions with only the required WC (toilet) breaks and eating our sandwiches (lunch) at our desks - much like in a working environment. Strangely - this highly regulative, if not ascetic environment was highly effective in learning all you needed to know to become a successful COBOL programmer really FAST the VZAP way.
My first Computer was Sperry-Univac/S80 in 1987, with COBOL 85. And I was a computer programmer also in COBOL for PC at that time, RM/COBOL with Editor-2 by IBM ( DOS 3.2). After that, for a while, with AS/400. My PC was z8088, at 8-10Hz. Happy times! With no Internet! or cell phones.
I find the hardest part of COBOL is not COBOL but the business processes that are behind the program itself. I worked with COBOL for about 5 years and didn't enjoy how may GOTOs without comments I came across.
That was my experience as well. It's like writing the sheet music for a song you wrote. If you know the song, writing the music is just a chore, but you have to have the song in mind first. COBOL translates well from whiteboard to source code.
Actually even in Cobol the goto is not recommended. I have seen goto statements mostly in old programs.The Great Grand Pa's hardly followed any coding standards during their time and debugging such programs is one of the hardest things I believe 🤔. But in programs which are comparatively newer "Perform" serves the purpose. But yeah I agree with you GoTo is a sucker in any language.😆
Ahhhh COBOL-D didnt have a PERFORM statement, therefore GOTOs had to be used I worked on ALL versions of COBOL on IBM mainframes. Because most shops used COBOL back in the 60s & 70s even 80s. I was an Assembly lang programmer then systems programmer that began in 1968. I even taught COBOL debugging in a large university.
You: Learning COBOL says "I want to work on the most important code running on the most important systems running the types of things that the world depends on." Me: I want to learn COBOL because I like money and job security
@@Babola10 I would not necessarily advise a young programmer to invest in COBOL while he/she has many year in front of him to learn and develop in trendy language la python and Javascript where the demand is growing. But for a middle age one, could make sense to slowly ramping-down to retirement on high-compensation job or mission in a low competition environment.
Thank you for this tutorial. I used to teach RM-COBOL/86 back from 1992-1995. From Front-End(GUI)and Back-End(File and Data Management) to How to print reports... This video was refreshing. But, I don't think going back to it is what we need. Computers are upgrading constantly and so are programming language. Goverment should spend money on computer upgrades instead of COBOL programmers.
@@adespade119 very true. I don't understand why that guy who used COBOL is now questioning on COBOL. No language can compete COBOL. It gives full control to programmer. If the program is written properly will never malfunction.
When i was in college in 98 we had this in our curriculum. Programming Cobol. I learned how to make a tic tac toe game. After just a year I quit computer programming. Now im trying to recall what i had learned during that time. If only id stuck around...
Luca Capelli very much so, the world is truly dependent on old mainframes and scarcely available engineers that know mainframes. IBM was panicking and paying for education for mainframe development / maintenance iirc.
memberwhen it's not that simple, works fine, switching could take a decade. I'd rather be the guy maintaining it for millions than the guy rewriting it for 300k a year.
21:23 -- I'm a little lost on what I'm supposed to be doing here. I have VS Code and Zowe Explorer set up and all that. I'm looking at the source code, but is there something I'm supposed to actually do with it? Submitting the JCL doesn't appear to give very much feedback on what's actually been done. Lastly, as I'm new to this course thing, is there some website I'm supposed to go to that lists any assignments, labs, or tasks I'll be completing as I'm going through this video? Or at least details specifically where to look for my assignments/challenges, and how submitting JCLs actually works?
Sir,it would have been great if short visuals/video clips were attached with this video itself. It would have been so easy to follow up in GitHub, IBM or Coursera later on. Beautiful course layout and your positive voice are the biggest add-ons here, remembering what I learnt here will be real easy. Thanks.
Variable names is where you can have some fun. Use names like Romeo and Juliette, so you can write code like - if Romeo and Juliette perform A100. If Romeo and not Juliette goto A999-End
Can a COBOL program written using VS Code on a Windows 10/11 be executed and permanently exist and operate in a Windows 10/11 environment? We want the program developed and operate on a Windows PC. If so, what version of COBOL does the final program run on a Windows PC? Or is it simply a plugin extension in VSCode?
77 levels are used to define a field that must start on a fullword boundary. They cannot be further sub-defined. Back in the day, they had to be grouped together right at the beginning of Working-Storage and therefore were easier to identify in an ABEND/DUMP situation. I stopped using them in the early 1980s. 01's and 77's are essentially the same except one can be further sub-defined, the other cannot.
Why is everyone like "Great tutorial! Learned a lot!"??? This ONE HOUR video didn't show a single line of code being written or executed. Yeah, there is a LOT of theory here, but that's kinda the point, here you are NOT learning cobol. you are learning what cobol IS. Which are two very very different things. One makes you a cobol developer, the other one makes you a guy who knoes ABOUT cobol.
Last time I did COBOL and RPG was in 1995. Is there a way to run RPG in linux yet? Not the games but the archaic language. When I first learned python I was thinking, position sensitive? Is this like RPG?
Would have loved it if they skipped the whole tedious visual studio method of coding and just provided a browser playground. But great tutorial all in all, best one i found
im here because one of the training center im studying now is openning this cobol subject, and they said it is one of the high paying job in a bank and financing industry. 😅
If you plan to work as a programmer or an IT in the financial/insurance/data industries, it is still wildly used. BUT you don't program in COBOL to have fun. You must also learn mainframe stuff that goes along most of the time. Or just try a free version on your PC just to get a "taste" of it...
