Hi Lionel,

are you using GRASS4.x or GRASS5.x?

You can use m.proj for projection and inverse projection of single
values or from a file. I suppose this is a new version of m.geo. But the
m.proj from GRASS4.3 only supports 7 different projections (one is
Lambert Conformal Conic, is that what you need?), the m.proj from
GRASS5.x has about 100 projections. 

If you want to use these projections with data, you have to create a
location with this projection. 

cu,

Andreas
