Dear Epidata list,
I am looking for a way to generate a date-variable from a 

i.e. I will type in the Danish central person registration number (10 
digits where the 6 first digits are the birthday ddmmyy) I would like to 
automatically create a date variable from this - to calculate ages at 
later dates.

I have looked for a chk that would do it, but couldn't find any.
Does anybody have a solution?
(and sorry if this has been discussed before, I searched and couldn't 
find any relevant discussion threads)

thanks in advance,
Drude Molbo,
