Copy value labels

[Senor Edward]

The function crcslbl can copy a variable's label to a new one. e.g. _crcslbl VariableA OldVariableA
I need to copy the value label of the old variable into the new one.
What is the STATA syntax for this?

Although I have no experience with - labmask -, I suspect this user-written program whose author is Nick Cox can do this trick for you.

I guess that you want one variable to be labelled according to the value labels of another. You could do that by using the name of the value labels in question or you can use macro extended function syntax to look up the value labels' name.
