I am not familiar with GRASSLANDS, but with GRASS, you must put the ungenerate
files in a directory named "arc" in your mapset in order to import them.

 do I need to write the file extensions (.lin, .txt, .pol, .lab)? Are these
file extensions rigth?
No, you do not have to add the extensions to the file names.

without file extensions (.lin for arc/info ungenerate lines file and .txt
for arc/info label-text file) but result is:

You probably have the file in the wrong place.  Make a directory called arc
and put them there.  Also, be sure to ungenerate as single precision.

>2) Can the GRASS category column in label-text file be the same that the ID
number column in label-text file ?

I offer GRASS support & will send you info on it in a seperate email.
