The best way is to use 
r.out.ascii grassmap > grassmap.asc

You then have to edit grassmap.asc to change the header of the ascii file 
to the format
required by Arc/Info's "asciigrid" command to convert to Arc/Info GRID.
This is easily done...
ASCIIGRID <in_ascii_file> <out_grid> {INT | FLOAT}
For eg., the header should be:

ncols 480
nrows 450
xllcorner 378923
YLLCORNER 4072345
cellsize 30
43 2 45 7 3 56 2 5 23 65 34 6 32 54 57 34 2 2 54 6
35 45 65 34 2 6 78 4 2 6 89 3 2 7 45 23 5 8 4 1 62  ...etc etc

All this info can be got by the header in grassmap.asc and g.region
Hope this helps...
