[pstricks] how does one draw a dashed line using psrticks

[Nwojo Agwu]

Hi,
I wanted to draw a dashed so I typed the following

\psline{linestyle=dashed}(x_{0},y_{0})(x_{1},y_{1}).

I received a Pstricks error message. Could someone please let me know what
the right command should be.

Thanks,
Nwojo
