Subject:      Lag values

Hello
I want to compute lag quarterly values after taking into account missing
quarterly values. I have already filled the holes (missing quarters with
missing values). For example, when computing the lag value of variable x
for year 2000 quarter 3, I would like to set lag x = . if x =. for year
2000 quarter 2.Any suggestions?
