ARCS <cover> {NOIDS | IDS | IDSONLY}
 
draws arcs using the current line symbol.
 
arguments
 
<cover> - the coverage containing the arcs to be drawn.  A <cover> prefixed by
a period (.) indicates a map library layer.
 
{NOIDS | IDS | IDSONLY} - specifies whether the arcs will also be labeled with
the arc User-IDs.
 
NOIDS - only the arcs will be drawn.  This is the default.
 
IDS - arcs and arc User-IDs will be drawn.
 
IDSONLY - only the arc User-IDs will be drawn.
 
notes
 
ARCS can be used whether or not <cover> has an AAT.
 
A map library must be selected with the LIBRARY command before ARCS can be used

with a map library layer.
 
If a set of arcs from <cover> has been selected using RESELECT, ASELECT or
NSELECT, ARCS will only draw those arcs of <cover> that are in the selected
set.
 
ARCS is used to draw arcs from a coverage using the current line symbol.  To
draw arcs using a variety of line symbols, use the ARCLINES command.
 
ARCS can also draw the arc User-IDs.  These are drawn using the current text
symbol and are positioned at the arc midpoints.  To label arcs with user-
specified text strings or with values from any attribute in the AAT, use the
ARCTEXT command.
 
Because <cover> does not require an AAT, ARCS may be used to draw all the
polygon boundaries in a polygon coverage.  Note, however, that if a set of
polygons has been selected from this polygon coverage using RESELECT, ASELECT
or NSELECT, ARCS will still draw all the polygon boundaries, regardless of the
selected set.
 
This is because ARCS does not use the PAT (it actually uses the coverage ARC
file).  To draw the boundaries of the selected set of polygons, use the
POLYGONS command.
