Embodiments relate to supporting creation of a manual of a program product. An aspect includes recording into a recording medium that can be accessed by the computer a screen character string, a translated character string where the screen character string has been translated to another language, or an identifier associated with the screen character string or the translated character string, displayed on a display device by the program product. Another aspect includes recording into the recording medium attribute information of the screen character string or the translated character string. Yet another aspect includes maintaining consistency between the screen character string or the translated character string and a character string that is displayed on a display device by an application for creating the manual, using the screen character string, the translated character string or identifier recorded on the recording medium and the attribute information.
