Hi all. Consider this script: <hansl> nulldata 12 setobs 5 2020-02-01 loop i = 6 .. 12 date = sprintf("2020-02-%02d", i) printf "%s -> %d\n", date, obsnum(date) endloop </hansl> the output I get is: <output> 2020-02-06 -> 4 2020-02-07 -> 5 2020-02-08 -> 6 2020-02-09 -> 7 2020-02-10 -> 6 2020-02-11 -> 7 2020-02-12 -> 8 </output> which is of course correct from Monday to Friday, but obviously wrong for weekends. What do you guys think we should do in these cases? I reckon we ought to return NAs, but I'm open to other ideas. ------------------------------------------------------- Riccardo (Jack) Lucchetti Dipartimento di Scienze Economiche e Sociali (DiSES) Università Politecnica delle Marche (formerly known as Università di Ancona) r.lucchetti(a)univpm.it http://www2.econ.univpm.it/servizi/hpp/lucchetti -------------------------------------------------------
