The DeterministicProcess command creates a new deterministic process. The parameter x is the value of the process. The value can be constant or time-dependent and can be given either as an algebraic expression or a procedure. A procedure defining the value of a deterministic process must accept one argument (the time) and return the corresponding value of the process. If the value is given as an algebraic expression, it must depend on a single variable.
