[SIC\]DEFINE LANGUAGE Name [Help_File] Define a new user language. User languages can be filled with user com- mands with DEFINE COMMAND. Their precedence against other languages is set by default to Automatic, use SIC PRIORITY afterwards to change it. If an help file is provided, the command HELP will look into this file for the language help (see SIC documentation for details). Else it will display a summary of all the language commands and their translations.
