The InputBox function displays a simple dialog box with the given Caption and Prompt message. It asks the user to enter data in a text box on the dialog. A Default value is displayed in the text box.

    value := InputBox('Name', 'Please type your name', 'Robert');
  until value <> '';

  // Show their name
  ShowMessage('Your name is '+value);
end;
