[Tutor] Help needed with script to batch-create shapefiles

Just a quick follow up for those of you who are interested. The batching script is now working and is attached below.
The intermediate step of saving the xy layer to a folder was unecessary and has been removed. The 'MakeXYEventLayer' command only creates "in memory" layers and not .lyr files on disk. Also, the 'FeatureClassToShapefile' command has been replaced by the 'CopyFeatures' command, since all that FeatureClassToShapefile does is call CopyFeatures multiple times. CopyFeatures is faster.
Thanks again to evryone who replied to my second posting.
#Import standard library modules
import win32com.client, sys, os
#Create the Geoprocessor object
GP = win32com.client.Dispatch("esriGeoprocessing.GpDispatch.1")
#Set the input workspace
GP.workspace = "C:/One"
#Set the shapefile output workspace
outputShapefiles = "C:/Shapefiles"
# Load required toolboxes...
GP.AddToolbox("C:/Program Files/ArcGIS/ArcToolbox/Toolboxes/Data Management Tools.tbx")
GP.AddToolbox("C:/Program Files/ArcGIS/ArcToolbox/Toolboxes/Conversion Tools.tbx")
#Get a list of dBase files in the input folder
fcs = GP.ListTables("*","dBASE")
#Loop through the list of dBase files
fc = fcs.Next()
# Set the outputname for each output to be the same as the input.
outxyLayer = fc.split(".")
#Convert each dBase table in the list into an xyLayer.
GP.MakeXYEventLayer_management(fc, "X", "Y", outxyLayer, "")
print "Made XYEvent layer %s with %i features" % (outxyLayer, gp.GetCount(outxyLayer))
#Convert each xyLayer into a shapefile
GP.CopyFeatures(outxyLayer, outputShapefiles + "/" + outxyLayer)
#Move to the next fc in the list.
print "FINISHED converting %s TO %s" % (fc, outputShapefiles + "/" + outxyLayer)
fc = fcs.Next()
# If an error occurred print the message to the screen
