                                                                atrbt_concat
Chapter 12 Attribute Operations

The atrbt_concat command is useful for combining multiple attributes assigned
to an object into a single string.  Some GIS applications cannot handle
multiple attributes; this command will make the attribute entries palatable for
such applications.  The concatenated attribute string will be stored according
to the action code parameter.

atrbt_concat

    Concatenates attributes for objects in specified set.

         atrbt_concat s action

    Concatenates all atributes for all objects in specified set s.

    Options/arguments:

         s         Set number, where:
                   0 - 31,   inclusive, are valid
         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.
    ___________________________________________________________________________
    Example(s):

    To concatenate individual attributes for each object in set number 8 for
    the current map and replace all attributes with the new one, enter:

         atrbt_concat 8 0
     
    More specifically, in an object in that set were to have three attributes
    (AW99, RW78 and PY76), application of the atrbt_concat function would
    result in the same object having an attribute of AW99RW78PY76 as one
    string.
