Building a geographic region

[David Hoover]

Greetings from Idaho!

We received some DLG-3 Optional files from a contractor that did not
contain header information.  What is a good way, and hopefully a quick
way, to build the easting and northing coordinates used to display
to data, either using g.region or the first screen in v.digit?  We have
a lot of these files and don't want to spend much time going into
v.digit to build the region data for each file.

Thanks in advance,
