Rocket® Visual COBOL®

Our Cobol apps run natively on a Linux host with just local logging files, and I was wondering if there is any documentation on emitting (Opentelemetry) traces to an external collector (via network).If not natively supported, maybe people have some other ideas how to bridge the gap? Maybe building some integration via “Consolidated Tracing Facility” (CTF)?Thanks for any idea!Tung

Good morning, I have been working in COBOL for over 20 years and I have always believed that when a main program (PA) calls a second program (PB) using `CALL PB USING field1 field2 field3` and the procedure in PB is `PROCEDURE USING field1 field2 field3`, the parameters that are put in the `using` procedure of a program (PB) should be defined in the `linkage` section, but I see in the documentation this“ Data-name-1 must be defined as a level 01 or a level 77 entry in the Linkage Section , File Section or Working-Storage Section”This raises a lot of questions for me.Has this always been the case? If the variables in PB are defined in the working storage section, what relationship do the variables in PA have with those in PB? How does assigning values ​​to variables in PB affect the variables defined in PA? Could the call be made from PA without passing those parameters?

This pertains to the use of external filehandlers, where my COBOL class is compiled with CALLFH"abcdef", which in tern needs to call fh/aaaaaa.dll which exists in the sub folder fh.The COBOL has :CALL “fh/aaaaaa” using ………During animation I debug the class, debug abcdef, but when it gets to the CALL “fh/aaaaaa” it doesn’t raise an exception but doesn’t execute the code either.I can see from procmon that the assembly was indeed loaded as well as the .pdb but just ignored almost as though it was looking for the programid but that didn’t match.Is this not supported?Is there an COBOL .NET  replacement for COBPATH ?Neil 

I am trying to call non-static Java methods from an executable file since static methods work fine in this environment.  I can accomplish this using cobjrun but it seems like the $java$ is not resolved correctly without cobjrun.I have tried adding all mf*.jar from the VisualCobol/lib directory into my CLASSPATH before execution but always get a load error similar to the following:Load error : file '$java$JavaCalculator'error code: 198, pc=0, call=1, seg=0198     Load failure Here are the files that show the failure:natcobol.cbl       $set ooctrl(+p-f)       program-id. natcobol.       class-control.          claJavacalled is class "$java$JavaCalculator".      * The above maps the Java class 'JavaCalculator' to the COBOL class name 'claJavacalled'       working-storage section.        copy "javatypes.cpy".           01 hCla            object reference.           01 l1              j

Does anyone know where I can get a copy of Visual Cobol?I have a book on the subject but the author gave the reader a bogus web address.Or do I just have to wait to be told where to go to get my copy of the compiler. I like working with Visual Studio Community. 

Hi,I am posting this question on behalf of a customer, to ensure it goes to the relevant forum and a place they they can see the post. Once I post this I'll share the link with the customer and ask to reply/comment here also.They ask:Does somebody know how to translate the following C#-Lambda-Command to Visual Cobol ?Example (the second last line):private void FlexGrid_Load(object sender, EventArgs e){string conn = Util.GetConnectionString();var ds = new DataSet();string[] tables = "Customers, Orders".Split(',');foreach (string tableName in tables){Util.FillTable(ds, tableName, conn);}// Defining relation between master and detail gridds.Relations.Add("Customers_Orders",ds.Tables["Customers"].Columns["CustomerID"],ds.Tables["Orders"].Columns["CustomerID"]);flexGrid.DataSource = ds;flexGrid.DataMember = "Customers";flexGrid.RowDetailProvider = (g,

Good morning.I'd like someone to explain how the cobutf8 utility works to see if we can use it in our company.We work with Microfocus Visual COBOL 8.0 for Eclipse (Unix/Linux).The database is Informix, and a few years ago we migrated to the UTF-8 locale.The OS has LANG=es_ES.UTF-8.However, some integrations with other companies require files with a fixed position structure. We've found that with UTF-8 encoding, there's a left shift for each UTF-8 character written. Currently, we've added calls to iconv before each move to the file variable, but that's very cumbersome when the file has many fields.

The following code crashes when it is executed within Visual Studio 2022: CALL GetCurrentDirectory  USING BY VALUE     PC-PATH-LENGTHBY REFERENCE CURRENT-PC-DIRECTORYRETURNING iRetEND-CALL.it fails with the error message: 173     Called program file not found in drive/directory: GetCurrentDirectoryAI updated the PATH variable to include the folders where the COBOL runtime exists. So why does it not find the Windows API function? Is this a limitation of the PE version or some other property to build has not been set correctly? Any help is appreciated. Kevin

Hi ,we works with Micro Focus Visual cobol 8.0 for Eclipse on linux/UnixWe have a program  with a file that we defines so:file-control.     select prevcob    assign to wk-prevcob     organization is line sequential.data division.file section.fd prevcob.01  reg-prevcob               pic x(185).and a working variable that defines the file structure as follows:01 wk-reg-prevcob-pru.    10 prevcob-nombre-pru            pic x(40)      value spaces.    10 prevcob-impdivisa-pru         pic 9(16)v99   value 0.    10 resto                         pic x(127).We define a cusor that obtains data from a database with UTF-8 locales in Informix and passes it to the variables of the working (the host variable are defined like pic x(300) and pic s9(16)v9(2))move clinombr                    to prevcob-nombre-pru

Is there any documentation on help in converting from Fujitsu COBOL to Visual COBOL? 

After installing the Visual COBOL PE, a took a utility program written in Fujitsu COBOL, to see how much of the source would or would not compile. There were few lines of code in the utility program that did not compile and I changed and/or deleted them so as the original source compiled successfully. However, the source included the COPY WINDOWS statement and that is where the majority of the errors occurred when compiled the windows.cpy file! My first thought was that the original source was to blame. I subsequently took the COBOL source template  file that is created when a new project is started. Below is the contents of that file:         identification division.       program-id. Program1.       environment division.       configuration section.       data division.       working-storage section.       COPY WINDOWS. *> pick up Windows defines       procedure division.           goback.       end program

I have requested to download Visual COBOL Personal Edition, but I have not received an email or reply to download Visual COBOL Personal Edition. What should I do so that I can download Visual COBOL Personal Edition?

The book is by Micro Focus, which is the previous owner of Visual COBOL. It references available materials at their website: http://www.microfocus.com/visualcobolbook. The book itself is copyright 2017 by Micro Focus. Following that link results in a 404 (page not found) error. Is there a current website that contains the materials related to the book?Concerning murach’s mainframe COBOL, the book is copyright 2004, Mike Murach and Associates, Inc. It also makes references to Visual COBOL, but given the copyright date, I can see any links provided in that book as being more outdated than the Visual COBOL book. Is there a current website that contains any materials related to that book?

I filled out the digital form with my email, as you are supposed to do to get the license to use the product. But I have not received a license code via email yet. I was hoping someone here could help me. 

I have successfully downloaded Visual COBOL. Reading the pdf, I find it talks about which versions of Visual Studio are supported. I think the doc may be somewhat outdated since it doesn’t talk about .NET 8 or Visual Studio Community 2022 edition. The first recommended topic to view is 8 years old, so I don’t think it applies. I am withholding installation until I know it will work with my system. I have:--HP Pavilion 64-Bit Gaming LaptopAMD Ryzen 5 Processor16 Gigs RAM1-TB Internal StorageWindows 11 Home EditionExternal 8-TB Solid-State Hard DriveVisual Studio Community 2022 64-bit Edition, Version 17.14.24Will Visual COBOL work with my system?

We currently have a native COBOL application that uses dynamic SQL (via OpenESQL) to fetch, insert and update into Microsoft SQL.This includes varbinary(max) columns which we have working and I suspect it was based on the demo which was available from this link https://community.rocketsoftware.com/rocket-visual-cobol-28/demo-using-the-varbinary-max-column-type-from-cobol-4560. Unfortunately the link to the actual demo is no longer available.I now have the fun and games of trying to convert this logic to .NET core Visual COBOL and I am really struggling to work out how to ‘stitch’ the 65k blocks back together into the correct format and would really appreciate some guidance on this (the same goes for splitting it into the 65k blocks to insert/update).Is there any chance for the demo mention

I think that no, but…Can I do something like that?:       77 lsMethod string.           Move 'gabert' to lsMethod           Invoke Classes lsMethod returning QuebraGalho  Hugs.Antonio JoãoVisual COBO + Visual Studio.

Hi! I am currently testing Visual COBOL 11 against my software, and when I run a program that has Database Connectors in them, I get a 9D,25 error on all the SQL tables that are in the program.Copilot tells me that the 9D,25 means the XFD is corrupt, but I re-created the XFDs and I am still getting the error. I re-created the Aculock DB, and made sure that my ACUFH file is pointing to the correct folder, and I have a valid license.  Is there anything else I can look at? 

I installed the latest Personal Edition of Visual COBOL.I'm trying to create a class that inherits from base and I'm getting the message "Inherited class 'Type base' not found".How do I fix this?
