    Thus, to define an output concept nun~ber of 285, and to attach it
    to node nun~ber 3 instead of the keynode, and also to double its
    weight, the user punches =285.3.*6 as an output concept number
    field. If, in addition, the concept number on node 2 is to be
    moved onto nodes 4 and 5 with half weight, another output concept
    nun~ber field would be added, the total reading:


                         =285.3.*6=N2.4.5.*3

c)  it is also necessary to supply the conditions specified for
    each node. For each node ex&ctly one node condition fiel& exists,
    except that conditions need not be specified for the last node
    (and adjacent nodes) if a definition using a tree type is en~loyed,
    and the syntactic and structural criteria supplied by the type are
    all that is needed for these trailing nodes.

    The first node condition field begins immediately after the output
    concept number fields. Each node condition field is followed by
    a slash, (I) except for the last node condition field which is
    followed by a dollar sign ($). If the tree is being defined
    according to a standard type, oniy the semantic information need
    be supplied in the node condition fields. If a type is being
    defined, however, or if a tree is being defined without the use of
    a type, all information `mist be supplied for each node. In this
    case, there ~st be exactly as many node condition fields as there
    are nodes in the final tree.

    If structural data is being specified, all but exactly one node
    condition field should begin with either an I or a D followed by
    an integer. The node whose condition field does not begin with
    an I or D is taken as the root of the criterion tree.  A node whose
    condition field begins with tInli niist match a node which is
    descended from (direct or indirect ancestor) the correspondent of
    node n~~er n. A node whose condition field begins with "~"
    must match a node which is the direct (first-generation) descendant
    of the node which matches node n. "Descend'1 is understood in the
