Quoting Nick Cox <n.j.cox@durham.ac.uk>:

There is a fairly systematic discussion in

SJ-9-1 pr0046 . . . . . . . . . . . . . . . . . . . Speaking Stata: Rowwise (help rowsort, rowranks if installed) . . . . . . . . . . . N. J. Cox
        Q1/09   SJ 9(1):137--157
        shows how to exploit functions, egen functions, and Mata
        for working rowwise; rowsort and rowranks are introduced

There is (now) not much difference in effect between my -rowsort- and Jeff Arnold's -sortrows-; note that there is also -rowranks- as well.

You could use Jeffrey Arnold's -sortrows- (use -findit- to locate download).

There's probably a proper name for the process I'd like to carry out.

Say I have five columns of information with staggard cell inputs.  How do I go about moving all the information in a subsequent column back through to the first column for which no information is missing on the row?

I'd like to go from something like this:

Col1   Col2     Col3    Col4    Col5

101     101
       111      333
                                935
                       023      016
405              295


to something like this

Col1   Col2     Col3    Col4    Col5

101     101
111     333
935
023     016
405     295
