st: compare files, vars only

[David Kantor <kantor.d@att.net>]

Hi.
Does anyone know of a program to compare the sets of variables in two 
data files? What I have in mind is something akin to -cf-, but...
 it would not compare values -- only the names of variables;
 it would not care whether the two data files had the same number of 
observations.

I was planning to write such a program, but I wanted to be sure that 
it hadn't already been done.
Thanks
--David
