Plotting 3D Surface Plots using data from an external file

I am trying to plot a 3D surface graph using data in a file of the form:

                  x1  y1  z1
                  x2  y2  z2
                      .
                      .
                  xN  yN  zN

This is the way that a plotting program called GENPLOT likes it.  

I have tried the following which, however, does not work:

         <<Graphics'Graphics3D'
         data=ReadList["datafile",Number,RecordLists->True]
         ListSurfacePlot3D[data]

I get an error message and a blank screen.  (These instructions came
from the Mathematica help-line).  Since my version of Mathematica
excludes support, I can not request more help from Wolfram.  They gave
me your net address for possible help.  

Thanks,
