Gen today = 15 May 2007
This should read as a string variable

Gen today2 = date(today, "dmy")
This will convert today into elapsed date format

Format today2 %dD_m_Y
This will allow today2 to be shown in the normal way

Then 
Gen age = (today2 - dob)/365.25
This should give you age in years with decimals.

Format age %2.0f if you want age as whole numbers.

I might have missed something - good luck

Dear Statists,

Could anyone tell me how to change a data set with dob to present age as
a
new variable please.
