st: Inserting a row in the data table

["Kartick Gupta" <kartick@mngt.waikato.ac.nz>]

Hello all,
Is it possible to insert a row in the data table? I know it is possible by running some simple program, but is there any function already available in Stata?

For example,
   
    ABC      --change to--->          ABC
1   x                                            .
2   y                                            x
3   z                                            y
4   .                                             z  

Regards
