LULC Files?

Hello!

I have recently obtained a set of USGS LULC files
split up into several catagories of :

  grid_cell
  land_use1 and 2
  political
  census
  hydro
  federal

I have used the following commands to import them
into grass

1. dd if=filename of=output ibs=8000 cbs=80 conv=unblock | m.lulc.read outfile
2. m.lulc.USGS outfile

I seem to get a blank screen after the computer has processed the
data. Am I missing some information about processing the data?

Thanks for any help
