Hi, now that the print command is generalized (in git), I tried the following line inside a function: print b.obsT b.p b.lagord b.T where all those bundle members are scalars. Then print interprets them as series IDs and spits out the following error: Variablennummer 434 außerhalb der Grenzen # variable number out of bounds *** error in function construct_bmats, line 1 I'm not saying this is necessarily a bug, but I find the error message confusing, although I understand gretl's internal logic (after thinking about it). Just want to make sure this is the intended status quo. thanks sven
