Hello,
On an annual dataset spanning from 1970 to 2010, I want to create a dummy valid  from 2005 and on.
I tried the following command line :
    genr D = (t > "2005")
but the newly created variable D has zeros only. Same result through the GUI.
Note that this script does work fine for a monthly dataset (let's say genr D = (t > "2005:01")).
best,
artur
