Dear Statalisters,

Nick's strategy to extract the varname from the e(wexp)-container works 
very fine, but  I  need for further calculations the content of the 
variable - its values in a vector of 8 subpopulations. How can I get 
back form the string expression extracted out of e(wexp), the name of 
the variable used for weighting, to its vector?

Thank you in advance

Wolfgang
