-labvalclone- is a wrapper for the creation 
and running of a do file defining a set of 
value labels, except that on each line of 
the do file the name of the value label 
is changed. 

For changing the labels in another file,
you could -label save- explicitly to 
a do file --- optionally change the value label name 
(e.g with the aid of a text editor) --- 
and run it with various data files. 

At its simplest, 

use A 
label save COLOURS using colours.do 
use B 
do colours
label val HUES COLOURS 

I once contemplated a -labelrename-. 
What put me off was mostly the thought 
that the program might be dangerous 
because of assumptions about what it did
and didn't do. That is, suppose you rename 
a set of value labels. You probably want 
to associate the newly named set with 
the variables its predecessor was previously linked to -- 
but you might not. It seemed better 
to leave users to work out the separate
steps they needed.
