Creating Your First Hello PL/I World Application

Create a project

You start by creating a Visual Studio project which is the container for your source code:

1. Start Enterprise Developer. If you need instructions, see To start Enterprise Developer.
2. In Visual Studio, click File > New > Project.
3. In the New Project dialog box, expand Installed > PL/I.
4. Click Native and select Console Application.
5. Specify a name for your project such as HelloPLIWorld and specify a location.
6. Uncheck Create directory for solution and click OK.

   This creates a solution and a project from the available templates in the specified location and opens them in Solution Explorer in Visual Studio.

Add a source file

The IDE creates a project with a template PL/I program. To demonstrate how you add files to a project, you'll delete this template file and add a new one:

1. In Solution Explorer, right-click the template program your project, Program1.pli and click Delete. Confirm deletion.
2. Right-click your project in Solution Explorer and click Add > New Item > PL/I Items, click PL/I Program, specify a name such as HelloWorld.pli and click Add.

   This adds a template PL/I file to your project and opens it in the editor.

3. Copy and paste the following code into the editor, overwriting the existing text:

   HelloWorld: proc options (main);
     put skip list("Hello PL/I World!");
   end HelloWorld;

4. Click File > Save All.

   You can verify now that your project compiles cleanly.

5. Click Build > Build Solution.

   The progress of the build is displayed in the Output view. There should be no errors in the build.

You can now run the application.

Run Hello PL/I world

To run the application:

1. From the main menu, click Debug > Start Without debugging.

   This opens a console window with Hello PL/I World! printed in it.

2. Press any key to close the console.

Preserve this project because you are going to use it again for other demonstrations.
