Chapter 9 Input Modes
*
The atrbt_copy command sets the graphic input mode to copy attributes from
one object to another using the current, active graphics input device (GIN).
*
atrbt_copy
*
*   Sets graphic input mode for interactive copy of attribute from one 
*   object to another using input from the current GIN.
*
*        attrbt_copy  otype  action
*
*   Sets the graphics input mode to allow copying of attributes to objects
*   using the current active graphics input device (GIN).  The attribute string
*   is specified by using the  start  command while the cursor is located on
*   an ojbect already has the desired attribute.   This will locate the polygon,
*   find its first attribute and display it.  The attribute is assigned 
*   by using the  continue  command while the cursor is located on the object 
*   to which the attribute is to be assigned.  Mulitple uses of the  continue  
*   command allow assigning the same attribute to multiple objects.  At any time
*   a new attribute string may be specified by using the  start  command again.
*   The attribute is applied to the otype object(s) as defined by the
*   action code.  The increment and decrement commands will behave like the 
*   continue command. 
*
*   atrbt_copy  otype  action
*   Options/arguments:
*
*        otype     Object type code, where:
*                  0 =  node
*                  1 =  segment
*                  2 =  polygon (def=same as map_type value in header)
*        action    Action code, where:
*                  0 =  Replace all attributes w/single new one. 
*                  1 =  Replace/set 1st attribute, leave others. 
*                  2 =  Replace/set 2nd attribute, leave others. 
*                  3 =  Insert new 1st attribute, push others up by one.
*                  4 =  Prefix 1st existing attribute.
*                  5 =  Suffix 1st existing attribute.
*                  6 =  Add a new (additional) last attribute. 
*                  7 =  Remove ALL attributes for one object. 
*                  8 =  Prefix 2nd existing attribute.
*                  9 =  Suffix 2nd existing attribute.

*   Example(s):
*
*   To copy the 1st attribute from the polygon at location 458, 122  to 
*   the 1st attribute for the polygons at 199, 200   and  53,466  enter:
*
*        atrbt_copy 2 1
*        start 458 122
*        continue 199 200
*        continue 53 466
*
*   To copy the 1st attribute from the polygon at location 458, 122  to 
*   the 2nd attributes for the polygons at 199, 200   and  53,466  enter:
*
*        atrbt_copy 2 2
*        start 458 122
*        continue 199 200
*        continue 53 466
*
*   To copy the 1st attribute from the node at 458 122 to replace all attributes
*   for the nodes at 199,200 and 53,466 enter:
*    
*        atrbt_copy 0 0
*        start 458 122
*        continue 199 200
*        continue 53 466
