reading US Army DTM

[Joao Ribeiro da Costa]

Hello GRASS users

After monthes trying to get it I got the US Army DTM for Portugal.
I received 5 scennes, in the form of 15 ascii files, apparently 3 files per
scenne (two header like, small and a big one). The files are now available on
disk.
We tried command
	m.dmaUSGSread
but we allways get the answer 
0-cols
0-rows

Any one with some experience in the subject??

thanks for the answer,
