the person telling you this is definitely wrong about things. Assuming you're
wanting a polygon coverage ungenerated, the procedure in Arc/Info is as follows:

	UNGENERATE line <cover> <ungenerate-file>
	UNGENERATE point <cover> <ungenerate-file>

this will ungenerate the lines and polygon labels in separate files. After
that, enter TABLES, select the *.pat file and UNLOAD the Info database to
a plain text file (take care of the items to be exported and the delimiter).
This will take two minutes maximum, and will give you a perfectly useful
input for Grass.

Good luck,
