[Gretl-users] accessing single elements of a series

Hi there, I am a bit puzzled by the grelt syntax. Why can I not use (s is a series) print s[1] but I can use scalar z = s[1] print z ??? It cost me some time to get it that actually accessing single elements works as it is written in hansl, simply because I did not understand the error msg from using the print command (I often use print or leading ? to check my understanding of syntax...). Also, in hansl it is said that one may use lagged_s =s[-1] to produce a lagged version of the series. But to no avail (at least not, if there are some NA included). Wheras the (undocumented?) lagged_s = s(-1) works (although grouped differently in the gui) Best Frederik
