Rocket® Visual COBOL®

My company currently uses Net Express 3.1 and will be migrating to Visual COBOL within the next several months.  We use the SPZERO compiler directive on majority of the programs we migrated off the mainframe several years ago.  This is due to having spaces in numeric fields on the old mainframe data files.  At the time of migration, it was better to use SPZERO than to modify the files/programs.  I read in the Visual COBOL documentation that SPZERO has been deprecated and is not supported in Visual COBOL.  Is there an alternate way to accomplish the same behavior as SPZERO in Visual COBOL? Thanks,Ben#VisualCOBOLautoscalemodescreenresolution#COBOL#netexpress

Hi everyone,If you’re interested in exploring a new GenAI capability that helps plan, generate, and analyze unit tests for COBOL, the AI Unit Testing for COBOL beta is a great opportunity to try it firsthand. Feel free to sign up or share this post with colleagues who may benefit. COBOL applications weren’t originally designed with unit testing in mind, which has made adoption notoriously challenging. In this beta program, you’ll gain hands-on experience with GenAI-driven unit testing and learn how to adopt it without making any changes to your production code. Learn more and register here: linkIf you have any questions, please reach out. I’d be happy to help.

HI,I am reading the book Visual COBOL. In my opinion the book is horrible. There is no punctuation in the code.  Since I am a beginner at this and Fortran, I’m not sure where it should go. So, I am putting periods at the end of every sentence. If you have read the book I am on page 14, doing the first program with Rental Agency. Also, there is no Capitalization in the text. S0, I am capitalizing words that I think are keywords.I have no idea if this is going to work.  I have another book Intro to COBOL. It  is better since it has done Cobol correctly. But I would like some help, please.Thanks for any help you can give me. Wow this site is very aggravating I keep getting post a public tag. I have 3 tags and it still is asking me for more tags, public ones.Mark

Hey everyone,As we step into 2026, one thing is certain: GenAI will remain a major topic this year.

This all works correctly with a Linux host of Centos 7 and Rocky Linux 8 but not with Rocky Linux 9. Host: Rocky Linux 9.4, docker 28.2.0 and MF Visual COBOL 6.0 When /var/microfocuslicensing/bin/startboth.sh is run as the docker image starts, lserv starts correctly and mfcesd seems to start but hangs so mfcesdchk fails to communicate with the license server.  A pstack of mfcesd shows: On a Rocky Linux 9 docker image:#0  0x00007fe3acf7c1f7 in close () from /lib64/libc.so.6#1  0x000000000040ab11 in daemonize ()#2  0x000000000040e7b5 in main () It takes over 10 minutes to actually start so that mfcesdchk returns correctly. I am just trying to debug if this is a docker on Rocky 9 issue or inside the mfcesd daemonize code.  Any ideas or trace info that can be turned on while mfcesd is starting up to determine where it is hanging?------------------------------Eric HardestyRocket Software Forum Member------------------------------

Hi. We are trying to setup a COBOL project, originally setup with Enterprise Developer (Micro Focus) for Eclipse, within VSCode using the Rocket COBOL extension. This project uses multiple folders, each of one hosted within different Git repositories. At first, we just imported the main folder, containing the main .cobolProj file from the original Eclipse project. However, no copybooks or other COBOL files referred from this .cobolProj file seems to be discovered by the extensión. We get COBCH0008 errors showing  "unknown copy file filename" for example, on COBOL files using the COPY directive. We then tried to import additional folders containing these copybooks into a VSCode workspace, but to no avail. Our question is :  Does the Rocket COBOL extension for VSCode work as expected, with a multi-folder project ? Just as an example, the <copybook> section of the main .cobolProj file looks like this: <copybook-paths xsi:type="copybookPathsSettings">         <path enab

What to do? As you do not get a lot of Patch Updates for Visual COBOL 7.0 for Visual Studio 2019 these days, help links still point to somewhere on microfocus.com It would be nice if they could work with the new home https://docs.rocketsoftware.com/bundle/visualcobol_dg4_70_html/page/GUID-CBF8DCDC-1F63-4C02-AC0C-7FABBE6A04AD.html I know help can be installed locally, but this is an additional support burden we would like to avoid if possible. Since this version is still supported, any plans to fix this in a PU?

Hi. We have few developers using licensed Enterprise Developer for Eclipse products (Micro Focus). They all have the same installation paths. Now they are trying to migrate to Visual Studio Code using the Rocket COBOL extension. However, one of them is having problems with the activation of the Language Server. Despite having configured the install location of the licensed product exactly in the same way as the others, the COBOL Language Server is not enabled. (Language Server Autostart setting is also set to true) When opening a COBOL file, VSCode detects it as a COBOL file,  but when checking the brackets on the VSCode status bar, (next to the COBOL file type) there's no information about the Language Server being used or enabled. If we type anything into any COBOL file, no errors are raised by VSCode. We have checked the output of  the Rocket COBOL extension, but there is no clue about what is going on. There's basically no information about any activity of the extension. So th

Hello, I'm working on a Visual COBOL application that connects to a relational database via ODBC. I want to know: What ODBC driver properties or attributes does Visual COBOL expect for proper functioning? Are there specific cursor types, transaction settings, or character set requirements? Any known limitations or recommended configurations for ODBC drivers with Visual COBOL?. Any guidance or references from Micro Focus / Rocket documentation would be greatly appreciated. Thank you!------------------------------Divya KoduriEngineerUnisys CorporationBanglore IN------------------------------

COBOL remains a cornerstone of global business operations powering 70% of the world's business transaction processing across industries such as banking, insurance, travel, retail, and government. However, running COBOL that has not been modernized – combined with outdated engineering tools and practices – can slow innovation, increase operational risk, and expose systems to today's security threats. Organizations with COBOL at their core can no longer afford to operate on outdated applications and systems or take unnecessary, expensive risks with application rewrite projects.  However, for many people, COBOL's reputation is clouded by a number of persistent myths and misunderstandings – even those familiar with COBOL may still judge it based on how it looked and operated over 30 years ago.

I've not ventured back to VS Code for a fair while, so have some questions and things that need clarification.My understanding for searching through the community posts what when you start vs code (such as from the command line 'code . ') if an existing .cblproj file exists it is read and the compile directives used, SQL directives and copybook paths.I seem to find this isn't true. To locate my copybooks I ended up creating a cobol.dir file and used COPYPATH(C:\\MF\\COPY;C:\\MF\\CPB)I also configured tasks.json: {     "version": "2.0.0",     "tasks": [         {             "type": "COBOL-MSBuild",             "command": "C:\\\\Program Files\\\\Microsoft Visual Studio\\\\2022\\\\Enterprise\\\\MSBuild\\\\Current\\\\Bin\\\\amd64\\\\MSBuild.exe",             "buildTarget": "${workspacefolder}/MyProg.cblproj",             "problemMatcher": [                 "$COBOLMSBuild"             ],             "group": "build",             "label": "COBOL: MSBuild (Compile Current File)",            

We are in the process of converting a native application to COBOL .NET and I would like to know a couple of things Is the use of SQLDA supported in COBOL .NET? If so then do I still need to set the address of sqldata(n) to a group entry as per below and process in 64k chunks or is there a better (easier) way? 01 obj-entry.    03 obj-len     pic s9(9) comp-5.    03 obj-str      pic x(65535). Ideally I would like to utilise a type String field but, as I have learnt, you cannot use ADDRESS OF on a native managed type so hoping for alternatives Thanks------------------------------Peter Restorick------------------------------

Hi everyone, The idea that COBOL is "stuck in the past" is one of tech's most persistent myths - and one of its biggest disconnects, given how much COBOL is still actively being developed. Even those once familiar with the language can struggle to see how it fits into a modern tech stack in the age of AI. Perhaps you're one of them? There's more than a grain of truth, of course - many COBOL systems do carry the weight of their history. Real-world COBOL often contains layers from different eras, as you'd expect from software that's delivered value for decades. But to examine a few lines of code written from 1980s or earlier and conclude COBOL has no place in modern IT is like dismissing smartphones because you once used a brick-sized mobile phone in the '80s. Don't let your memory of COBOL - as it once was and when you once wrote it - cloud your judgment of what it's capable of today. And perhaps most regrettably, don't let that lead you to trade it for something that's little more tha

Software used:   Microsoft Visual Studio Professional 2019 Version 16.11.42   Micro Focus Visual COBOL 8.0    Operating System: Windows Server 2022 Datacenter   Problem Description:   We have few Micro Focus Visual COBOL program executables running as Windows services. These .cbl programs were created using 'Console Application, COBOL' option in Visual Studio editor. The built .exes were converted to services using NSSM (Non Sucking Service Manager). Requirement now is to eliminate NSSM and create core Visual COBOL code that runs itself as Windows services without help of any third party tool. Is this feasible with a project created with 'Console Application, COBOL' options? ------------------------------Kavitha NatarajanRocket Software Forum Member------------------------------

In Native COBOL you can have something like this:        01 MyData.           05 MyString1        Object Reference.           05 MyString2        Object Reference.           05 MyString3        Object Reference.           05 MyString4        Object Reference.           *> This is just a simplist list, there could be 100's       01 ProgramToCall        PIC X(6).       procedure division.           *> Program Names are build dynamically and called in a variable.          move "ABCDEF" to ProgramToCall          Call ProgramToCall using MyData Now moving to COBOL .NET this has to change as Object References must be on an 01 Level.

Serveral questions here all in regard the the RunUnit in COBOL .NET.1. In COBOL .NET you can spin up a RunUnit and do work, then suspend the RunUnit in a rununitcache (ConcurrentDictionary).A ConcurrentDictionary is stored in process, is there any way to store a suspended RunUnitin Redis or something similar?So if you are scaling out across servers you could pick up that RunUnitregardless of the server you hit via it's id or something?2. What else could I do with a RunUnit other than start, stop, dispose, SetUserData & GetUserData that might add value?3. Can you get the ID of a RunUnit inside the RunUnit? 4. Is there a limit to amount of RunUnit's you can spin up under say C# rest api? Neil ------------------------------Neil HayesSoftware Development Specialist------------------------------
