  • How to compile COBOL program?

    There are many ways to compile the COBOL program. Version control tools like Endevor or Changeman are used to compile the COBOL program in a real-time environment. Also, we can use standard JCL to compile the program. The compile JCL for the COBOL program is as follows -

  • What is mategj COBOL srclib?

    In this example, MATEGJ.COBOL.SRCLIB is the source library used to code the program and the program name is FIRSTPRG. Note! The module name and program name with PROGRAM-ID should not be the same. However, to avoid confusion, specify both names as one. Refer to the screenshot below. There are many ways to compile the COBOL program.

  • Does OpenCOBOL support tabs in source?

    Putting that together, you are using Windows, tabs, and a version of OpenCOBOL which doesn't like tabs in source. You have two things to do directly to get it working, and you may want to get the latest version of GNU COBOL when it is convenient for you.

  • How to use GnuCOBOL on Windows?

    To complete our preparations for using GnuCOBOL on Windows, we need to do the following: 1. Point VSCode to the GnuCOBOL folder The VS Code editor should display the new folder c:gnuCobol on the left side, as seen here 2. Add the CLS01EX01.cob source file

GnuCOBOL

Although there are several COBOL dialects available most of them are very expensive and not open source. Therefore, we’ll be using GnuCOBOL, a project formerly known as OpenCOBOL. And because the Windows installation is much harder to accomplish than those with Linux & Mac, this article will be focused on Windows only. However, the language itself

Configuration

By default your new COBOL compiler expects to be located underC:\\GnuCOBOL. Personally, I don’t like to put my binaries directly under C, so I’ve moved them to C:\\bin\\GnuCOBOL. However, this can provoke some dire consequences as cobc.exe, the compiler, will still try to reference includes and libraries from the default directory. But before we solve

Compiling Helloworld

Although I’m not aiming to teach COBOL syntax in this article, we should at least be able to compile the traditional HelloWorld program. If for nothing else, then just to show you a few important details that come to light when one starts writing COBOL source codes. For example, COBOL treats spaces & tabs very differently, so expect to run into wei

Utilizing The Win32 API

With GnuCOBOL we can also compile programs linked with Win32-libraries. In the example below we CALL a public Win32 function MessageBoxAto display text in a message box. The compilation command contains some new flags: cobc -x hellow.cob -W -fstatic -l User32 -fstatic enforces static generation of all external calls as static. -llinks the program w
