st: time-series operator in -foreach- loop

[Finne H�kon <Hakon.Finne@sintef.no>]

Dear Statalisters,

With data -tsset- :

. gen event = 0

. foreach i in 1/10 {
  2. replace event = 1 if D`i'.group==1
  3. }
D1 not found
r(111);

. replace event = 1 if D1.group==1
(6589 real changes made)

. 
Why doesn't -foreach- read D1. as a time series operator, and which is the
better workaround?
