Thanks for the quick response...

Perhaps I'm missing something... but the command I'm using is supposed to 
*read* the .e00 file and *write* the shapefile... so why would ogr2ogr be 
writing a .e00 file?  Do I have something backwards, or is there an 
intermediate step I'm not aware of?

                        Thanks...
