[Gretl-devel] environment variables in gretl script

Hi, I am now back to using gretl on Windows (more often at least). So finally I tested py4gretl on win and of course it fails. Actually I think it probably also would fail in most desktop ways of using it, even on *nix. The reason are the missing write permissions in the current directory (./), where py4gretl (both gretl and python sides) stores two temp files. That "current" (at the time of invoking gretl) directory I guess will often be the installation directory of gretl, where a normal user cannot write. So I am thinking of other places to store the temp files. However, py4gretl needs to pass that information from the gretl side to the python side, so it's name must somehow be accessible from gretl script. Hence my question: what type of environment variables can be used in a script? Or any other ideas on a good place to store temp files (on all supported platforms)? Thanks, Sven
