Thanks for your reply Hamish. I have the following set up:
I am running Grass v6.4 in Windows XP I have FWTools2.0.4 installed (for the GDAL library) I have also installed gdalwin32-1.6 I have Proj4 v4.4.6 Win32 release installed I also have Python 24, 25 and 26 My GDAL_DATA env variable is currently set to C:\program files\FWTools2.0.4\data and my PROJ_LIB variable to C:\program files\FWTools2.0.4\proj_lib Does GRASS uses these environment variables? Where does GRASS look for its projection library? >From the GRASS cmd line in my GB location, the g.proj -p command gives: -PROJ_INFO-------------- name: Transverse Mercator proj: tmerc datum: osgb36 ellps: airy lat_0: 49 lon_0: -2 k: 0.9996012717 x_0: 400000 y_0: -100000 no_defs: defined -PROJ_UNITS------------------ unit: metre units: metres meters: 1 I hope this clarifies something.

(multiple versions in different places for different needs) what does "g.proj -p" report?
