This sparked a thread to which Eric Booth, Scott Merryman and Martin Weiss contributed. 

I concur with the view that -reshape long- is often the best advice. 

That said, one program mentioned was -sortrows- from Jeffrey Arnold at SSC. 

The help of -sortrows- refers to a program of the same name by myself, but there is no such program. That is a slip for my -rowsort-. For a broader review of working row-wise, see

Is there a way to sort or reorder dates using the foreach  
command--perhaps using the egen function in the loop or something?

How do I get:

Date1          Date2         Date3         Date4

23July1997    01Jan1997     12Sept1997     03Feb1997

to be ordered thusly:

Date1          Date2         Date3         Date4
01Jan1997     03Feb1997     23July1997     12Sept1997
