This system variable replaces the placeholder %P in Sd dialog static text fields and string passed to the SdSubstituteProductInfo function. This system variable is automatically initialized to the value of the system variable IFX_PRODUCT_NAME; if you assign a new value to IFX_PRODUCT_NAME the value of IFX_PRODUCT_DISPLAY_NAME does not automatically change.

Note • The system variable IFX_SETUP_TITLE specifies the text in the title bar of all built-in dialogs.
