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

Dear All, 

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 Also, the 'FeatureClassToShapefile' command has been replaced by the 'CopyFeatures' command, since all that FeatureClassToShapefile does is call CopyFeatures multiple times.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. 

Regards, 

Chris.

    while fc:

        outxyLayer = fc.split(".")[0]

        #Convert each dBase table in the list into an xyLayer.
        GP.MakeXYEventLayer_management(fc, "X", "Y", outxyLayer, "")

        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()

except:
    traceback.print_exc()
    # If an error occurred print the message to the screen
    print GP.GetMessages()
