There is a bug here (more below) but the short answer is: use set force_decpoint on and then gretl in German will behave in the same way as gretl in English with regard to sscanf. In addition, if you really, really want to output a "csv" file with decimal commas when running gretl in English (something that is not at all recommended, and therefore is not made easy), consider this example: <hansl> open data4-1 set csv_delim semicolon store horrid.csv string s = readfile("horrid.csv") s = strsub(s, ".", ",") outfile horrid.csv --write printf "%s", s outfile --close </hansl> OK, here's the bug mentioned above. What happens if you trying using sscanf on numerical values that use the decimal comma, when running gretl in German (or any locale that uses the decimal comma), without doing "set force_decpoint on"? You might expect that either (a) you'd get the same effect as when running in English (truncation to integer) or else (b) you'd get the full numerical value. But up till now you'd in fact get an error condition. Bug! For the present I've "fixed" this (in CVS) such that you get the full numerical value, but I'm not at all sure that's right. That needs further discussion. Allin _______________________________________________ Gretl-users mailing list Gretl-users(a)lists.wfu.edu http://lists.wfu.edu/mailman/listinfo/gretl-users
