5.5.13 ‘@L’: Set language

‘@Ll’ sets the language to l, where l is one of ‘{c,c++,n,n9,r,r9,v,x}’. See Languages.

There are shorthand forms of this command for some languages; see ‘@c’ (ATc), ‘@c++’ (ATcpp), ‘@n’ (ATn), ‘@n9’ (ATn9), ‘@r’ (ATr), and ‘@r9’ (ATr9).

Generally, the global language should be set in the limbo section by means of ‘@L’, ‘@c’, etc.  rather on the command line by options such as ‘-L’ or ‘-c’.
