I agree, these would be useful outputs. But unlike merge, which can do many
things and thus often needs to be checked (via tab _merge, etc.), append in
the mode that it is usually used is a one-trick pony: it just concats the
datafiles. Now I see that it is capable of doing fancier things, and
sometimes that might be what someone is trying to do. But I guess something
that would give a warning when the number of variables in the two datasets
differ, and a severe warning when they lack any commonality, would be
helpful. In my experience, most of the time when using append one doesn't
think that either of those conditions should occur.
Even better, how about having -append- return the number of common
variables, and the number of unique variables from the master and using
datasets? Then one could automate the checking of whether it worked...
