The main documentation of the Initialized_Base_Structure Procedure contains additional explanation of this code listing.
function Initialized_Base_Structure (Structure) result(Initialized) ! Use associations. use Caesar_Flags_Module, only: initialized_flag ! Input variable. ! Base_Structure to be checked. type(Base_Structure_type), intent(in) :: Structure ! Output variable. type(logical) :: Initialized ! Initialized condition boolean. !~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ! Verify requirements - none. ! Set initialized boolean. Initialized = Structure%Initialized == initialized_flag ! Verify guarantees - none. return end function Initialized_Base_Structure
