You shouldn't try.
First, -reshape- one or the other so that you have two data files with
compatible structure, and then -append-.
Second, it's not even clear that this is an -append- problem. It sounds
more like -merge- to me.

Subject: st: appending to a file
I have two files. One in long and one in wide format.
In the long file, I have observations at the group level:
group x y
1
1
1
1
2
2
2
2
k
In the wide file, I have data at the group level, including a variable
day:
group day x y
1 1
2 1
3 2
4 2
5 3
k
How can I append the day variable from the wide file to the long file?
