{   This procedure  manages  adding  a  member into the active set table for a
{ particular set.  The  set  must  must  have  already  been  located  and  is
{ specified  by  the  ast_index  parameter.  This routine gets an unused entry
{ into the member entry list for the set, and then stores the fields into  the
{ new  entry.   All  fields  will  be  initialized  by this procedure, and are
{ indicated by the input parameters.
