# if dataset is not of time series, which is wierd, but anyway
gen varlag=var[_n-1]
# if dataset is of time series or cross-sectional or panel ("L." is the operator)
tsset timevar, panelid
gen varlag=l.var
or
by panelid: gen varlag=var[_n-1]

panelvar and datevar are the wrong way around
Thanks for your comment.
Actually it doesn't matter. Stata will know the difference.
necessita di verificare:)
I saw your posting, and am wondering if you can help me with lag variable in STATA 11SE.
I am trying to run a regression for sales=c+beta(newsreporting) + salesL where salesl suppose to be infinitely lagged. but I am having trouble creating the lagged sales variable for some reason
