The value labels that are attached to a variable have a 
name. The line you mentioned creates a local macro called 
`lab' containing that name if the variable w_`var' has 
value labels attached to it, otherwise the local macro 
`lab' contains "", i.e. an empty string.

You can read more about this in -help extended_fcn-.

Hope this helps,
Maarten
