CRUISE now provides a C-Function input area for adding component extensions or defining a control algorithmn directly within CRUISE. This mode enables the user to write functions in standard C-syntax. Most of the ANSI C operators and statements can be used, e.g. the 'IF-ELSE'-statement. In this mode it is also possible to define up to 99 input and 99 output variables which can be used by other components through the Data Bus.
