[GRASS-user] Error trying to display vector maps

[Carlos Dávila]

Hello all
Each time I try to display any vector map, I get the error that follows:
d.vect map=roads color=0:0:0 lcolor=0:0:0 fcolor=170:170:170 
display=shape type=point,line,boundary,centroid icon=basic/circle size=5 
layer=1 lsize=8 xref=left yref=center llayer=1
Sorry, <layer> is not a valid parameter

ERROR: value <roads> out of range for parameter <map>
       Legal interval: point,line,boundary,centroid,area,face

ERROR: Required parameter <output> has not been initialised:
    ...
Same maps in other computer don't give error. Using 6.3.cvs.
Can anyone tell me what is wrong?
Regards
Carlos
