Allin, This wonderful tool you made, "validate" is giving some strange characters in the output when gretl_commands.xml is tested. It messes the terminal output, by turning on graphic chars mode. Please use: validate gretl_commands.xml | less (instead of using more) Attached are examples of the files for you to see using an editor.
