Betreff: st: compare files, vars only
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
