 Such a partition has to be solved with a \emph{solver method} of \cref{solver-methods}.
 When \lstinline!previous(x)! is used on a continuous-time state variable \lstinline!x!, then \lstinline!previous(x)! uses the start value of \lstinline!x! as value for the first clock tick.
 
-The use of the operator sample from \cref{event-related-operators-with-function-syntax} in a clocked partition is problematic.
+The use of the operator \lstinline!sample! from \cref{event-related-operators-with-function-syntax} in a clocked partition is problematic.
 Diagnostics are appropriate especially if it is intended to generate sampling faster than the clocks, and otherwise the sampling should ideally be adjusted to the clock ticks.

 Since the goal is that it should be possible to use \emph{every} continuous-time Modelica model, it is not forbidden.
