Description

This command allows you to define a set of non-geometric attributes which may
then be attached to a single or selected group of entities.  You may also
delete change or display attributes in the group.

The attributes are added or updated in the following format:
         name=value
To delete the attribute, you only need to specify the name.

Each string may be up to 20 characters but when displayed using the `s'
option, the string is shortened to the first 16 characters.  You may define up
to 10 attributes in the group.  The attributes are written into a temporary
file called USERATTR.ARC in the current directory.  This file must not be
edited and it is limited to 233 characters.

In order to query the attributes attached to an entity, use the \qent command.
To obtain a report use the \atrep command.

NOTE 1: Do not use attribute codes used by the system.  These are listed in
the DUMP.DOC file in the \ARCA directory.
NOTE 2: This command will not affect attributes set by the \atrib command!
