Re: [Gretl-users] script: open Stata data file - save string-table

However, it seems to me that the variables that you are referring to aren't really string series in the Stata source file. Notice the double explanation in gretl's string table at the top -- first it says "at least one non-numeric variable", then it says "furthermore some mappings from numerical values to labels were found which are printed below"  [re-translated from German here]. Now, if you look at the variable called "version", gretl reports a "String/Code" table and that works alright, as you've said already. (In German: "Zeichenketten / Code -Tabelle") BUT: For variable "caseno" gretl reports something else in English (perhaps this string isn't marked for translation yet in the sources): "Value -> label mappings". For example -5 is mapped to 'other missing'. Actually, it happens that these codes never really appear as values in this series, but this is just a special case I think. So I believe the original series is numeric in Stata's file, and that's why it is imported as numeric. Stata itself would use the value/label mappings to display the values' string codes I guess. If I'm correct, in the end your question then seems to be a (valid) feature request: On importing Stata files with value/label mappings, can this meta information be retrieved somehow in a structured way. But it doesn't have to do with string-valued series I think. Let's see what Allin has to say about that, but in general I suggest to file a ticket on the feature request tracker. Right now I don't have a solution with gretl. Perhaps there exist some other tools to query the meta information of a Stata data file. cheers, sven
