Hi, Artur and I wanted to try something with Ox, but we ran into an error message about an "unmatched {". See this example: <hansl> function void heyho(void) foreign language=Ox main() { } end foreign end function heyho() </hansl> It seems the gretl parser is trying to enforce its rules for other foreign languages as well. Some months ago the script that now produces this error worked (I think). The error appears both on Win and on Linux. cheers, sven
