[Gretl-users] setobs using variables

Hi, I am using gretl 2016b-git on Windows (x86_64) with build date 2016-02-02. I ran the following script: scalar anzahl = 1000 nulldata anzahl setobs anzahl 1:0001 --special-time-series The log script follows: ? scalar anzahl = 1000 Generated scalar anzahl = 1000 ? nulldata anzahl periodicity: 1, maxobs: 1000 observations range: 1 to 1000 ? setobs anzahl 1:0001 --special-time-series 'anzahl': not a scalar starting obs '1.0001' is incompatible with frequency Error executing script: halting Why is anzahl not a scalar? I explicitly declared it to be so. How can I make the first observation 1:0001 depending on anzahl? Should I build a string? Thank you and kind regards, Thorsten
