Nobody understand what you try to do Please try to explain so every one can understand

Hi thank you so much , my job was system administrator on mainframe I left this job since 2006 How I can refresh my info VAS/ESA VSE 2.1 Ciccf Vsam and Sam file The difficult job was unload and reload data Because in that time Need to do this procedure every month To delete the gaps inside hard disk Now big gap between 2006 now 2024 but it was an amazing job never have it again

In case you thought a silent tutorial video was kind of cool, it's not!

link drivers pls

good

good

Hello, is there a possibility to use Vs Code /Cobol with DB2? Do you have any example?

I see a fellow notepad.exe enjoyer :>

Which COBOL is this? I came back to the language and I can´t believe that most programming is still done employing the old fixed-format source code, and archaic editors. Useful additions related to screen usage, by the way. Thank you for sharing.

GRACIAS DE CORAZON TE AGRADESCO ESE FAVOR. SALUDOS DESDE MEXICO.

Hi, How do I clear the screen in this version of COBOL?

Now do TPF.

Thank you very much!!! Your video was so helpful!! I watched a lot of videos before this one, and nothing was useful for me, besides I liked your voice, it's pleasent to hear it as I'm not a native english speaker!!

And then you got a VSAM DATABASE harhar

Thanks for the vid. Nice refresh. I was a CICS programmer in the 80's and 90's. Fun Times.

Can you please add videos about client/server applications. Where front-end uses GUI based language like Java using JSON as io file and the back-end is COBOL CICS. What else do we need to know about mainframe modernization?

I hope more IT experts and beginners alike find these videos to learn enterprise COBOL. COBOL is easy to learn. Large banking and financial companies are still using it these days. I hope to help teach COBOL again using these tools here.

I have not yet register to have access to zOS mainframe. Just syntax checking right now my COBOL/CICS programs. May I ask if there is expiration to mainframe access? Can I try Stored Procedures, Channel and Containers instead of COMMAREA. ALso, finding a nice debugger. Separating presentation logic, business logic, and data access programs to try web services using JSON files.

You say COBOL have no idea about DB2, but DB2 knows COBOL because Stored Procedures can be written in COBOL. I'm right? Thank you!

Thank you for this very useful video!

Very Helpful

Audio is non existent

thank god finally one of these without an indian accent

sir make video on crosstab

Let say you are in a Mainframe lpar, how/where to know if you have an IMS DB? Which are the files you need to create in order to create a dbd and begin to fill with data? Thank you!

Thank you for this very useful video!

Thank you for this very useful video!

I was a system programmer back in the 70s. I remember updating the CICS tables for new programs, terminals & databases. You had to shit down CICS and re load it to bring in the new tables. CICS 1.3 under DOS/VSE. The first 4 characters of the 3270 stream were blanked out so an application could plug in the 4 character program name of the next program to run when any PFAID key or ENTER key was pressed.

Your reference to the SQLDA reminds me of the following, which may be useful to you. I worked from 1981 with SQL/DS, supporting customers in the DOS/VSE and VM/CMS implementations. When DB2 came along, I used the same approach there, and it worked well. The original SQL/DS manuals stated explicitly that dynamic SQL could only be exploited in Assembler and PL/I. However, the constructs for PREPARE and the rest were there in COBOL. I tried it out, and this it what the books should have said. “You can build dynamic SQL, but the target COBOL variables referenced in the SELECT list must match the data coming in as the results of the FETCH”. In other words, it reflected the fact that COBOL couldn’t allocate storage dynamically in response to the values in an SQLDA. An early customer in. CICS/DOS/VS wanted to display a screen with many fields that the user could use in various combinations to narrow down their search, but the result list was always the same. So the SQL statement was built up in sections, starting with “SELECT NAME, RANK, NUMBER” After that, each field input from the screen was tested, and if it was not blank, the appropriate additional WHERE clause was added. No attempt was made to allow for AND/OR sophistication. Once the statement was complete, it was PREPped and run. This was used by number of other customers, and when DB2 came along it worked in exactly the same way. I don’t know if the DB2 books made the same restrictive statement, but it was directed at the limitations of COBOL, not of the data base or the SQL interface.

Great job and a lot of useful information. I’m looking forward to the IMS and especially the CICS flavors of working with DB2 and COBOL.

Thank you sir

Wonderful video ! I did connect to mainframe. This time I want to connect again using my favorites. Howto do that ?

Thank you for this very useful video!

Hola buenos dias. Por favor me puedes enviar el link par inscribirme. y asi poder resibier el la url el usuario y clave para poder ingresar y HACER LOS EJEMPLOS.....Milgaraca por tu ayuda u orientacion

Do you use GnuCOBOL?

Nice to see enterprise COBOL can be learned by those interested to learn mainframe. I used to teach COBOL using PC version separate from the JCL because my students then are not allowed to have access to the terminals connected to mainframe.

Now I understand! Thanks!

In 1989 I choose COBOL under DOS 3.3 (over DBase III +, which rest of the classmates choose as they feared COBOL compiler errors :-) ) wish I could get my hands on a mainframe till this day.....

I worked on a CICS system (utility customer service) back in the 70s and 80s, when most of the transactions were written in Assembler; the majority of which were limited to 12K bytes. The mainframe probably had 8MB of storage - and was supporting up to 2000 terminal operators - with under half second response.. Migrating to Cobol and Command Level was quite a revolution.

I 'retired from CICS' 16 years ago after working with it for 26 years. Fascinating to see the zOS elements which were barely beginning to appear when I signed off! One minor observation: the start rather implies that CICS is for the finance industry only. Its true power is its flexibility across all business areas (manufacturing, commerce, government), and across a huge variety of enterprises from tiny (CICS on a 370/125 with 128K) to enormous.

NO ❗

Very good presentation. I am a retired COBOL Analyst Programmer and preparing to re-enter this rewarding career. Glad to know that COBOL is not dead. That it is continuing to evolve. Also, great that there is Open Mainframe project where beginners and experts can be able to learn COBOL or refresh. Thanks! Sonny Z.

where is the course book?

Is IBM Enterprise COBOL free?

Thank you so much for your help!

Wish I had that years ago! Thanks!

Very good! Who is the presenter, please? And are there other videos by this presenter?

hi, you presenter said something about "info on the emal", this course is free to take? i would like to take that course.

HOLA. YO QUISIERA APRENDER SOBRE SCREEN SECTION PERO PARA EMULAR UNA GRID ES DECIR VARIAS LINEAS CON VARIAS COLUMNAS

I am a Cobol beginner, excellent information
