Hi, I'm seeing that the basic ISO date representation isn't recognized by the smpl command: <hansl> open djclose smpl 1989-01-01 1989-12-29 # works smpl 19890101 19890110 # fails </hansl> First, daily data dates formats aren't explained in the smpl reference. (Only in the manual in the "join" chapter, I think.) Secondly, is it intended or just an oversight that basic ISO doesn't work, or is there some deeper issue? (Given that the manual says that "basic format is more suitable for computer processing", one might expect it to be supported in scripting.) OK, I suppose a plain integer ISO date number could in principle be mistaken for the obsnumber, is that the reason? (However, the dataset needs to have at least 1e7 observations to overlap with that number range.) thanks sven
