Hi Allen Version 0.41 is very fast again, as fast as using the older API of dbnomics. Thank you very much for the new version using the new API of dbnomics. But unfortunately 0.41 produce very often errors. One common error is: ? list X = dbnomics_bundles_to_list( bs, "series_code" ) File exists*** error in function dbnomics_bundle_get_data, line 28 called by function dbnomics_bundles_to_list *** error within loop in function dbnomics_bundles_to_list or one not so common error is: ? bundle spec = defbundle("mask",".DEU+FRA..Q") ? bs = dbnomics_get_multiple(provider, database, 1000, 0, spec) Datenfehler *** error in function sanitize_url, line 2 called by function build_parms called by function dbnomics_get_multiple I attache two scipts for examble, running either on gretl 2021a or 2021b for Windows. Sometimes there is no error when I run the scipts again after it produced errors in the first run. Klaus
