[Gretl-devel] varlist inside function (and furthermore strange append effect)

Hi, for the first thing, here's a minimal example: <hansl> function void checko(list L) list L print # d_LRY d_LRM (expected result) varlist # weird: 0) const 5) [masked] 6) [masked] end function open denmark list L = LRY LRM checko(diff(L)) </hansl> OK, then in my use case I'm also using 'append' (inside the function) to load data from a csv file. The first part of that csv file contains the same data as in the list L, with the same series names. However, afterwards it seems that for example d_LRY appears twice in the dataset - at least it's the result of an empty "print". ("varlist" doesn't show duplicates, but again has these [masked] entries as before with large series ID# gaps.) How to avoid the duplication and get a "sane" dataset view inside the function? thanks sven
