IDENTIFICATION DIVISION.PROGRAM-ID. HelloWorld.PROCEDURE DIVISION. DISPLAY 'Hello, World!'. STOP RUN.
To compile this COBOL program, open your terminal or command prompt, navigate to the directory containing your source file, and execute the following command:
cobc -x hello.cob
Upon successful compilation, an executable file named `hello` (or `hello.exe` on Windows) will be generated. To run the program, simply execute the produced file by entering:
./hello
While the process is generally smooth, new users may encounter common errors during compilation. An often-seen issue is the “unrecognized statement” error, which usually indicates a syntax error in the COBOL code. It is advisable to carefully review the code and ensure compliance with COBOL syntax rules. Another common problem might be related to missing or misconfigured library paths, which can hinder the successful execution of the compiled program. Users are encouraged to check their environment variables and adjust them accordingly.
