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

    The debugger interprets the expression specified in an EVALUATE
    command as a language expression, evaluates it in the syntax of
    the current language and in the current radix, and displays its
    value as a literal (for example, an integer value) in the current
    language.

    The current language is the language last established with
    the SET LANGUAGE command. If you did not enter a SET LANGUAGE
    command, the current language is, by default, the language of the
    module containing the main program.

    If an expression contains symbols with different compiler-
    generated types, the debugger uses the type-conversion rules
    of the current language to evaluate the expression.

    The debugger can interpret and display integer data in any one
    of four radixes: binary, decimal, hexadecimal, and octal. The
    current radix is the radix last established with the SET RADIX
    command.

    If you did not enter a SET RADIX command, the default radix for
    both data entry and display is decimal for most languages. On VAX
    processors, the exceptions are BLISS and MACRO-32, which have a
    default radix of hexadecimal. On Alpha processors, the exceptions
    are BLISS, MACRO-32, and MACRO-64, which have a default radix of
    hexadecimal.

    You can use a radix qualifier (/BINARY, /OCTAL, and so on) to
    display integer data in another radix. These qualifiers do not
    affect how the debugger interprets the data you specify; they
    override the current output radix, but not the input radix.

    The EVALUATE command sets the current value of built-in symbols
    %CURVAL and backslash (\)  to the value denoted by the specified
    expression.

    You cannot evaluate a language expression that includes a
    function call. For example, if PRODUCT is a function that
    multiplies two integers, you cannot use the command EVALUATE
    PRODUCT(3,5). If your program assigns the returned value
    of a function to a variable, you can examine the resulting
    value of that variable. On Alpha processors, the command
    EVALUATE procedure-name displays the procedure descriptor address
    (not the code address) of a specified routine, entry point, or
    Ada package.

    operators and constructs, see the Language_Support Help topic.
