3 Simple Ways to Check Your COBOL Version

Checking the version of COBOL is crucial for software developers to ensure compatibility, maintainability, and adherence to industry standards.

Different versions of COBOL may have varying features, syntax, and capabilities, impacting the behavior and functionality of the code. Identifying the specific version used in a COBOL program or system is essential for troubleshooting, upgrades, and ensuring optimal performance.

There are several methods to check the COBOL version, including examining the compiler or interpreter used, inspecting the program’s source code, or utilizing operating system commands. Each approach provides a unique perspective on the version information, allowing developers to verify and manage their COBOL applications effectively.

1. Compiler/Interpreter

Identifying the COBOL version is critical for ensuring compatibility, maintenance, and adherence to industry standards. The compiler or interpreter plays a pivotal role in this process, as it provides valuable version information during the compilation or execution of the COBOL program.

• Version Display: Compilers and interpreters often display the COBOL version they are using during the compilation process. This information is typically presented in the form of a version number or a copyright notice that includes the version details. For example, the GNU COBOL compiler (GnuCOBOL) displays the version number as part of its startup banner.
• Command-Line Arguments: Some compilers and interpreters offer command-line arguments or options that specifically output the version information. For instance, the OpenCOBOL compiler provides a “–version” option that prints the version details to the console.
• Built-in Functions: Certain COBOL compilers and interpreters may provide built-in functions or intrinsic functions that return the COBOL version. These functions can be invoked within the COBOL program to retrieve the version information at runtime.
• Object File Metadata: In some cases, the compiler or interpreter may embed the COBOL version information into the generated object files or executables. This information can be extracted using tools like the “objdump” utility on Unix-like systems or the “dumpbin” utility on Windows.

By leveraging these techniques, developers can easily determine the COBOL version associated with a specific program or system, enabling them to make informed decisions regarding compatibility, upgrades, and maintenance.

2. Source Code

Analyzing the COBOL source code offers another valuable approach to determine the COBOL version. By meticulously examining the code, developers can uncover vital clues that point to the specific version employed.

• Version-Specific Directives: COBOL compilers often introduce directives or pragmas that are specific to particular versions. These directives can explicitly specify the COBOL version or enable features that are only available in versions. For instance, the “VERSION” directive in Micro Focus COBOL can be used to set the COBOL version for the compilation.
• Informational Comments: Developers may include comments within the COBOL source code to document the version of COBOL used. These comments can provide a clear indication of the version, especially in cases where other methods may not be readily available.
• Generated Code: Some COBOL compilers generate code that contains version information. By inspecting the generated code, such as the object code or assembly code, developers can potentially identify the COBOL version that was used.
• Legacy Code: In the case of legacy COBOL applications, the source code may contain references to older COBOL versions. These references can serve as indicators of the COBOL version that was originally used to develop the application.

By carefully examining the COBOL source code and looking for these indicators, developers can gain valuable insights into the COBOL version used. This information is crucial for understanding the capabilities and limitations of the code, ensuring compatibility with other systems, and guiding decisions related to maintenance and upgrades.

3. Operating System Commands

Utilizing operating system commands offers a straightforward approach to ascertain the COBOL version. These commands leverage the capabilities of the underlying operating system to retrieve version-related details about the installed COBOL compiler.

• Command Invocation: On compatible operating systems, executing commands like “cobol -version” or “cobol –version” in a terminal or command prompt displays the version information for the COBOL compiler. These commands are typically recognized by the operating system and can be used to query the compiler’s version.
• Version Output: The output of these commands generally presents the version number of the installed COBOL compiler. This information can be crucial for determining the specific version being used and understanding its capabilities and limitations.
• Cross-Platform Compatibility: The availability and functionality of these commands may vary across different operating systems. Some operating systems may provide built-in support for COBOL-related commands, while others may require additional configuration or the installation of specific utilities.
• Command-Line Interface: These commands operate through the command-line interface, which requires users to have familiarity with command-line navigation and syntax. This approach may be less accessible for individuals who prefer graphical user interfaces or who are new to command-line environments.

By harnessing the power of operating system commands, developers can conveniently retrieve the COBOL version information, enabling them to make informed decisions regarding compatibility, upgrades, and maintenance.
