[pstricks] [Help]How to draw a piecewise function with pst-plot

Hi all,
I'm trying to use pstricks to plot some functions with pstricks in LaTex.
And now some problems have occurred to me.
Here's a piecewise function or subfunction f(x):
f(x) = 1 while x <= 0
f(x) = 0 while x > 0
and I tried to use pst-plot : \psline[linecolor=red](-3,1)(0,1)
\psline[linecolor=red](0,0)(4,0)
but I donnot know how to make the coordinate (0,0) to be a hollow dot, while
(0,1) is a solid dot.
And another problem is that I also tried the IfTE : \psplot{-3}{4}{
ifTE(x>0,0,1) }, but pstricks tried to connect the line y=0 and the line y=1
to be a continuous line.
Can anyone tell me how to fix the problem, thanks very much.
A newfish to LaTex and PSTricks.
