Hi, the following script throws an error and halts: <script> open greene14_1 catch smpl (Q<0) --restrict </script> which gives: <output> ? open greene14_1 # balanced panel w/o missings Lese Datendatei /usr/local/share/gretl/data/greene/greene14_1.gdt Periodizität: 15, max. Beob.: 90 Beobachtungsbereich: 1:01-6:15 Liste 7 Variablen auf: 0) const 1) unit 2) year 3) C 4) Q 5) PF 6) LF ? catch smpl (Q<0) --restrict Keine Beobachtung würde ausgelassen! Fehler bei Skriptausführung: Stopp </output> IMHO it would be in the spirit of 'catch' to let this script continue, no? (BTW, never mind the misleading message "Keine Beobachtung würde ausgelassen!" which is a translation bug, probably long-standing and AFAIR not introduced by me. I will correct that soon.) thanks, sven
