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

    The debugger recognizes the syntax, data typing, and scoping
    rules of each language. It also recognizes each language's
    operators and expression syntax. Therefore, when using debugger
    commands you can specify variables and other program entities as
    you might in the source code of the program. You can also compute
    the value of a source-language expression using the syntax of
    that language.

    This appendix describes debugging techniques that are common to
    most of the supported languages. The help topics provide further
    information specific to each language:

    o  Supported operators in language expressions

    o  Supported constructs in language expressions and address
       expressions

    o  Supported data types

    o  Any other language-specific information, including
       restrictions in debugger support, if any

    For more information about language-specific debugger support,
    refer to the documentation furnished with a particular language.

    If your program is written in more than one language, you can
    change the debugging context from one language to another during
    a debugging session. Use the SET LANGUAGE command with the
    keyword corresponding to your language choice.

    On VAX processors, you can specify one of the following keywords:

    ADA        BASIC     BLISS      C
    C++        COBOL     DIBOL      FORTRAN
    MACRO      PASCAL    PLI        RPG
    SCAN       UNKNOWN

    On Alpha processors, you can specify one of the following
    keywords:

    ADA        AMACRO    BASIC      BLISS
    C          C++       COBOL      FORTRAN
    MACRO      MACRO64   PASCAL     UNKNOWN

    When you are debugging a program written in an unsupported
    language, enter the SET LANGUAGE UNKNOWN command. To maximize
    the usability of the debugger with unsupported languages, this
    setting 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. For information about the operators
    and constructs that are recognized when the language is set to
    UNKNOWN, type Help Language_UNKNOWN.
