We consider numerically the crossover scaling behavior from the directed percolation universality class to the compact directed percolation universality class within the one--dimensional Domany--Kinzel cellular automaton. Our results are compared to those of a recently performed field theoretical approach. In particular, the value of the crossover exponent $\Phi$ = 2 is confirmed.
