LANGUAGE - Variable defining the language
The global variable LANGUAGE is a string. It defines the language to use for the on-line help and various menus. At the present time, the values of LANGUAGE can be "eng" for English, which is the default, or "fr" for French.
This variable is defined in the startup file scilab.star . It can be changed there.
When launching Scilab, you can also give the value of language as an argument: scilab -l <language> for Unix and runscilab.exe -l <language> for Windows.
