Delphi is a general-purpose language based on an Object Pascal dialect with its roots coming from Borland Turbo Pascal. It comes with its own IDE designed to support rapid application development (RAD).

It allows cross-platform native (compiled) application development from a single code base. Currently supported platforms are Windows, OSX, iOS and Android.

It comes with two visual frameworks:

  • VCL: Visual Component Library specifically designed for Windows development wrapping Windows native controls and support for creating custom ones.
  • FMX: FireMonkey cross-platform framework for all supported platforms

Cross-platform Hello World using FireMonkey

program CrossPlatformHelloWorld;


{$R *.res}

  ShowMessage('Hello world!');

Most of the Delphi supported platforms (Win32/Win64/OSX32/Android32/iOS32/iOS64) also support a console so the WriteLn example fits them well.

For the platforms that require a GUI (any iOS device and some Android devices), the above FireMonkey example works well.

Hello World

This program, saved to a file named HelloWorld.dpr, compiles to a console application that prints "Hello World" to the console:

program HelloWorld;


  WriteLn('Hello World');

Show 'Hello World' using the VCL

This progam uses VCL, the default UI components library of Delphi, to print "Hello World" into a message box. The VCL wrapps most of the commonly used WinAPI components. This way, they can be used much easier, e.g. without the need to work with Window Handles.

To include a dependency (like Vcl.Dialogs in this case), add the uses block including a comma-separated list of units ending with an semicolon.

program HelloWindows;


  ShowMessage('Hello Windows');

Show 'Hello World' Using WinAPI MessageBox

This program uses the Windows API (WinAPI) to print "Hello World" into a message box.

To include a dependency (like Windows in this case), add the uses block including a comma-separated list of units ending with an semicolon.

program HelloWorld;


  MessageBox(0, 'Hello World!', 'Hello World!', 0);
