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

    The DUMP command displays the contents of memory, including
    registers, variables, and arrays. The DUMP command formats its
    output in a manner similar to the DCL command DUMP. The debugger
    DUMP command makes no attempt to interpret the structure of
    aggregates.

    In general, when you enter a DUMP command, the debugger evaluates
    address-expression1 to yield a program location. The debugger
    then displays the entity stored at that location as follows:

    o  If the entity has a symbolic name, the debugger uses the size
       of the entity to determine the address range to display.

    o  If the entity does not have a symbolic name (and, therefore,
       no associated compiler-generated type) the debugger
       displays address-expression1 through address-expression2 (if
       specified).

    In either case, the DUMP command displays the contents of these
    locations as longword (by default) integer values in the current
    radix.

    The default radix for 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.

    Use one of the four radix qualifiers (/BINARY, /DECIMAL,
    /HEXADECIMAL, /OCTAL) to display data in another radix. You can
    also use the SET RADIX and SET RADIX/OVERRIDE commands to change
    the default radix.

    Use one of the size qualifiers (/BYTE, /WORD, /LONGWORD,
    /QUADWORD) to change the format of the display.

    The DUMP command sets the current entity built-in symbols %CURLOC
    and period (.) to the location denoted by the address expression
    specified. Logical predecessors (%PREVLOC or the circumflex
    character (^)) and successors (%NEXTLOC) are based on the value
    of the current entity.
