Subject: st: RE: labels
One solution here is to use -label save- 
before the append and then use the 
created .do file afterwards.

I have 2 files with the same variables "name" and "color". Variable 
"color" is an integer variable with a label, but the label is
defined in each file, thus depending on the values of the variable
"color" existing on each file. The problem is just that when I
want to append the 2 files, I lose the labels of the values
which are on the file I want to append, but which are not on the
master data. I don't know how to do to append some label to the
first label...maybe there is an easy way to do so (except to
generate only one label first because I have a lot of files with
the same variable already labelled)
Let's have an example :
data1 :
 list
    +-----------------+
    |    name   color |
    |-----------------|
 1. | georges    blue |
 2. |  robert     red |
 3. |  simone    blue |
    +-----------------+
but in fact, variable color has a label :
. label list
typocolor:
          1 blue
          2 red
data2 :
list
    +------------------+
    |    name    color |
    |------------------|
 1. |  alfred      red |
 2. | monique   yellow |
    +------------------+
. label list
typocolor:
          2 red
          3 yellow
And when I do (on data1) "append using data2", I have :
. list
    +-----------------+
    |    name   color |
    |-----------------|
 1. | georges    blue |
 2. |  robert     red |
 3. |  simone    blue |
 4. |  alfred     red |
 5. | monique       3 |
    +-----------------+
. label list
typocolor:
          1 blue
          2 red
The value "3" which is not in data1 has no label after the append 
command. Someone has an idea?
