Or perhaps the stucture of your workfile does not fit. By the way, I personally prefer performing ODBC operations with scripts, because it much easier to alter the code and to reuse it. In terms of importing data via ODBC I've got another general question myself: obs-format combinded with string (%s) does not work, or to be precise, GRETL crashes immediately! Could someone provide an example for such string indices? E.g. I want to load for 4 Countries GER, UK, JP, CN the CPI and WPI series in the following order: GER CPI GER WPI UK CPI ..... I succeeded in using numbers instead of Names (1:1; 1:2; 2:1...). But if it's possible to use the strings with %s it would be even nicer. Thanks in advance Pindar
