Testing the installation

To test the product installation and the critical search paths, build and run a sample application.

1. Create the following Fortran program and name the source file hello.f:

         PRINT *, "Hello World!"
         END

   Note: Each line must have six blank spaces before the first text character.
2. Compile the program:

   If you have set up the short invocation commands, enter the following command:

    xlf hello.f -o hello

   If you have not set up the short invocation commands, enter the following command:

   installation_path/xlf/15.1.5/bin/xlf hello.f -o hello

   where installation_path is the installation location of the compiler packages. If the compiler has been installed to the default location, installation_path is /opt/ibm/.
3. Run the program by entering the following command:

   ./hello

   The result is "Hello World!".

4. Check the exit code of the program by entering the following command:

     echo $?

   The result is "0".
