The algebra of Communicating Sequential Processes provides a facility to formal specify systems by describing their behavior. To be able do denote these systems more precisely it is useful to introduce state variables. Because the CSP algebra deals with concurrent processes, the state variables are shared between those processes. This contribution describes techniques how to represent shared variables in CSP utilizing common features of CSP without any extension to the algebra.
