[Gretl-users] loop command

I don't understand what's wrong ! I work on an annual data file with 20 observations spanning from 1971 to1990 and create a dummy variable by using " loop for i=1971..1990 ". When looking at the printout, changes are reported for each iterations but finally, displaying the dummy variable I see no change . I replace the loop by "i=1..20" and it worked fine . Moreover, the time series plot doesn't show the usual graph's left margin, the thin fine-looking space between Y-axis and the drawing (see attached).
