That's right.

I believe it is the command "levels", right? (just found that out)

Thanks so much for your suggestion.
One question: I have version 8.2 of Stata so I don't have the "levelsof" command. Is there anyway of geeting this plug-in for my version? Or is there a similar version of this command for Stata 8.2? I believe this command would be very useful to me even in other contexts (that not the value labels).
Thanks,
MA_V

Thanks for the plug. I'd have to recommend -labmask-
myself as probably the most user-friendly solution here.

If it didn't exist, the problem yields to a few lines.

* check the assumption of correspondence in
your desired direction:

bysort var1 (var2) : assert var2[1] == var2[_N]

(compare:
How do I list observations in a group that differ on a variable?
http://www.stata.com/support/faqs/data/diff.html)

* get the distinct values of -var2-:

levelsof var2, local(levels)

foreach l of local levels {
    su var1 if var2 == "`l'", meanonly
    label def var1 `r(min)' "`l'", add
}

By assumption the values of -var1- given -var2-
are identical. So we can do a look-up by a -summarize-
of those values, and add a new value label each
time around the loop.

Then we link the labels to the variable:

label val var1 var1
