Creating the 'Hello World' application

1. On the Welcome Page of the RAD Studio, click Create a new project, select Console Application, and then click OK.
2. In the Code template that is displayed in the Code Editor, enter the following:
   • For Delphi, enter the following statements after the try keyword and before the except keyword:

   Writeln(‘Hello World (From RAD Studio!)’);
   Readln;

3. Save the application.
4. In the Project Manager, right-click the Target Platforms node, and in the Select Platform dialog, select 64-bit Linux, and then click OK.

   Tip: To activate the platform, select the Make the selected platform active check box or double-click the needed platform in the Project Manager.
