The "how" depends on what sort of program you're calling gretl from (and on what platform), and how informative you want to be if something goes wrong. In C the quick and dirty way is system("gretl-executable datafile"); where gretl-executable and datafile would have to be wrapped in quotes if the paths contain spaces. But note that by default gretl expects to be able to read its configuration from the user's home directory. If you want to bypass that you can use the environment variable GRETL_CONFIG_FILE, as described at http://gretl.sourceforge.net/slave/ . Allin Cottrell
