Subject:      Hierarchical structure

    Hi all,
 
    I have a data set that represent a hierarchical structure (i.e. in tree way)
and each record there is the code and the code of their parent record.
I need to make other code with all the info for the level, i.e.:
 
          1st level -> a
          2nd level -> aa
          2nd level -> ab
          3rd level -> aaa
          3rd level -> aab
               ...
 
  I need to do this in a easy way. Please, if s.o. has done that before
tell me,
 
            Thanks in advance,
 
 
                       Joaquin
