If the output parameter is not given then the data is sent to standard output.
If old version is requested, the output files from v.out.ascii is placed in the $LOCATION/$MAPSET/dig_ascii/ and $LOCATION/$MAPSET/dig_att directory.
If layer > 0 then only features with a category number will be exported. Use v.category to add them if needed or define layer=-1 to export also features without category.
v.out.ascii in the old version mode (-o) does not copy the dig_cats file associated with the binary vector input map to the new output file name. The user must copy the dig_cats file to the new output name if this is desired (e.g. using the UNIX cp command).
It is possible to output the coordinates of vertices in a non-points vector feature by first converting the vector feature to a points map with v.to.points and then exporting with v.out.ascii in points mode.
