Library /sys$common/syshlp/dbg$help.hlb DEBUG, SET, LANGUAGE, /DYNAMIC, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    When you start the debugger, the current language is set to that
    in which the module containing the main program is written. This
    is usually the module containing the image transfer address. By
    default, when the scope of the program being executed changes to
    a module written in a different language, the debugger changes
    the current language to that of the module.

    You can prevent the debugger from automatically changing the
    current language with the SET LANGUAGE/NODYNAMIC command.
