Problem: If the RM/COBOL runtime, or, compiler abnormally terminate, then, the use counting mechanism can become corrupt.  This scenario will cause any future instances of the runtime/compiler to fail with a "unauthorized use message (loc 810). Resolution: The full text of the Loc 810 error is : System function error (Loc 810) - Semaphore OK but shared memory marked bad.The "rmucutil" utility will show that there is a shared memory issue. Either reboot or reset the locked "shared memory" to resolve the problem.Below is the syntax for the "rmucutil" utility, located in your RM/COBOL installation directory:rmucutil xx-xxxx-xxxxx-xxxx runtime|compiler detailsThe "rmucutil" utility will show that there is a shared memory issue. If the output shows there is a shared memory or semaphore issue, you can clear shared memory and semaphores manually if the ipcs (for Inter Process Communication Status) commands are available on your operati

We have a number of tables in Microsoft SQL that are defined as uniqueidentifier. When accessing this column type the OpenESQL interface, using ODBC, returned this column type as a char(36).Modifying our native code to .NET and using ADO it appears that this column type is returned as a 16 character binary column type.My question is whether you are aware of this and whether there are other column data types that behave differently when using ADO as opposed to ODBC? Peter

Hello Team,Currently we have Enterprise developer already available in the system , I am trying to integrate VS Code using Rocket COBOL extension to do a BRD documentation using the Co-pilot features. We have two copybooks extension ,one with CPY and another COPYCOB. The intelisense is  able to identify the CPY copybooks but not the COPYCOB eventhough the extensions are mapped. Is there possibility to re-use the XML files of MFED for the integration of VS code.ThanksSanoop

I am trying to code Cobol programs, compile and execute. I need help on what I need to download to accomplish this. I  have worked on IBM mainframes using Cobol, jcl, ISPF, TSO, etc many years ago. I want to restart now. Please advice on what I need to do to get started. Thanks.

I have a relational database with a one-to-many table. When reading it in COBOL, I believe it's necessary to read the record key from the main table and the related records from the secondary table; I believe a read should be performed from the main table record key, and the related records from the secondary table would be stored in an "occurs" of that record.The  code  FD :  FD ARCHIVO-NUEVO.01 REG-NUEVO-FISICO.05 Fis-RecNumber PIC 9(6).05 Fis-Nombre PIC X(30).05 Fis-Tabla-Pagos.10 Fis-Nuevo PIC 9(8) OCCURS 100 TIMES. Is correct???Thanks

Hi everyone,I downloaded Visual COBOL for Eclipse Personal Edition Ubuntu 11.0.zip, but I am unable to complete the installation because of a license issue.The bundled license XML file appears to contain the following License Group:Visual COBOL for Eclipse Personal Edition_Windows-RPv1Since this is the Ubuntu/Linux download, I expected the license file to be for Ubuntu or Linux, not Windows.Has anyone else seen this issue with the Ubuntu 11.0 Personal Edition download?Is this Windows-RPv1 license XML actually valid for Ubuntu/Linux, or is the wrong license file included in the download package?If this is not the correct file, how can I obtain the correct Ubuntu/Linux Personal Edition license XML?Thanks.

Hi everyone!With the release of Rocket ACUCOBOL extend 11, you got the support for the most popular dev tool out here, Visual Studio Code.  Now you can equip your teams to develop ACUCOBOL applications in VS Code, simplifying hiring / onboarding and speeding up development.See the extension in action in the short demo:Let us know what Rocket ACUCOBOL demos you’d like to see in the future in the comments.  

I have Visual COBOL + Microsoft Visual Studio on my Windows 11  laptop. I inadvertently deleted the shortcut that I used to launch Visual COBOL+VS. I cannot figure out how to restore the shortcut. Can anyone advise me on how to rebuild the correct shortcut? Thanks

Hello everyone,I just (6/4/26) download Visual COBOL for Eclipse Personal Edition Windows 11.0.zip   The C:\ProgramData\Micro Focus\CommuterLicFile.xml file is empty.License Administration cannot gener license.Anyone can help with generating trail license? How? Thanks.MA

We have a user that is on a Dell Laptop and two different times they have ran the Dell System Update process and Bench (ver 9.2) has started locking up on projects.  When this happens they get a “NOT RESPONDING” error from Windows and have to shut it down bench with task manager.  At times they can reboot the machine and it will work for a bit then start locking up again.  We have reinstalled bench on the machine but that did not fix the issue.  The only solution that worked was getting a new machine for that user but we don't want to do that again since this issue has now appeared on the new laptop also.Has anyone seen this happen after a system updates and if so how did you solve this issue? 

Good afternoon, is there a way to make acu-gt print using the same font as acutoweb?It seems that the font and size settings in the configuration file are ignored by acu-gt. 

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. 

To show records of a vision file we use paged-grids and the majority of our users are fine with that.There is one customer (and unfortunately our most important one) who wants a “standard scrollbar”.The answer that this is only doable when we know how many records are 100% does not convince him and he does not let it go.So we thought of a lazy-loading scenario.We load and show the first 100 records and when he drags the grid thumb all the way down to the end of the grid we try to load more records.The problem is that the grid does not give an event when reaching the last record.Does anyone have an idea how to solve this ?Or do you have a totally different approach ?

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

I’ve been using VC11 for Eclipse (Windows) for a couple of months now, and this seemly random highlighting of this is really getting on my nerves.  The image below shows a “simple” example.  It is often much worse.Here I just put my cursor on the top left and then cursored down some lines.  When my cursor reached line 14 the entire line, plus the first 3 characters of line 15, were suddenly highlighted for seemingly no reason.  Cursoring down again it removed highlight from 14 and highlights 15.  Other examples seem to be even more random.  Is this a known issue or what?  Anything I can do?  The only way to unhighlight is to open the Find box (Cntl-F) and then hit escape. 

I came upon the following and figured I’d give it a try:  https://docs.rocketsoftware.com/bundle/netexpress_ug_51wrappack1_html/page/opclap_15.htm#s016As long as the ACTUAL-PARAMS compiler option is specified immediately before the template class (my term), you can build out the full class with the specified name and based on the specified class parameter.  Specifically “$SET ACTUAL-PARAMS(ELinklist Employee)” will build the ELinklist class with Employee being the “parameter class”.  Specifically, the parameter class “Element” in the source for PLinkList will be replaced with actual class Employee.But what if I want a second one, say ALinklist with class Another as the parameter?  If I put “$SET ACTUAL-PARAMS(ALinklist Another)” below the earlier ACTUAL-PARAMS it will create ALinklist, but ELinklist seems to be gone.I can post my exact source code if necessary.
