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. To
    debug a module written in a different source language from that
    of the main program, you can change the language with the SET
    LANGUAGE command.

    The current language setting determines how the debugger parses
    and interprets the names, operators, and expressions you specify
    in debugger commands, including things like the typing of
    variables, array and record syntax, the default radix for the
    entry and display of integer data, case sensitivity, and so on.
    The language setting also determines how the debugger formats and
    displays data associated with your program.

    The default radix for both data entry and display is decimal for
    most languages. The exceptions are BLISS and MACRO, which have a
    default radix of hexadecimal.

    The default type for program locations that do not have a
    compiler-generated type is longword integer. This is appropriate
    for debugging 32-bit applications.

    It is advisable to change the default type to quadword for
    debugging applications that use the 64-bit address space (on
    OpenVMS Integrity server systems, the default type is quadword).
    Use the SET TYPE QUADWORD command.

    Use the SET LANGUAGE UNKNOWN command when debugging a program
    written in an unsupported language. To maximize the usability
    of the debugger with unsupported languages, SET LANGUAGE UNKNOWN
    causes the debugger to accept a large set of data formats and
    operators, including some that might be specific to only a few
    supported languages.

    Note that SET LANGUAGE UNKNOWN can be an easy, quick workaround
    for language-related problems because it uses the "loosest" set
    of rules.

    For information about debugger support for language-specific
    operators and constructs, see the Language_Support help topic.
