In addition to the advice given by Nick Cox, you may want to check carryforward on SSC.
ssc desc carryforward
ssc install carryforward

This embodies some of the ideas in the FAQ into a program.

        2/03    How can I replace missing values with previous or
                following nonmissing values?

I have the following data after using the _tsappend_ and the _predict_
command, how do I add the same ticker name to rows 237-240, without
listing "AAPL".  I will be working on panel data and after the predict,
I will need it to extend the ticker names to the _tsappend_ rows.

        Ticker  Forecast     Date
234.    AAPL   -3.15e-09   2010w38
235.    AAPL    5.20e-10   2010w39
        ------------------------------
236.    AAPL   -8.58e-11   2010w40
237.            1.42e-11   2010w41
238.            -2.34e-12   2010w42
239.            3.86e-13   2010w43
240.            -6.37e-14   2010w44
