(Kept debugger only.) Opens a process dump for analysis with
    the System Code Debugger (SCD). The qualifier /PROCESS_DUMP is
    required and distinguishes this command from the one that invokes
    the System Dump Debugger (SDD), ANALYZE/CRASH_DUMP.

    The qualifier /IMAGE_PATH=directory-spec is optional, and
    specifies the search path the debugger is to use to find the
    debugger symbol table (DST) files. The debugger builds an image
    list from the saved process image list. When you set an image
    (the main image is automatically set), the debugger attempts to
    open that image in order to find the DSTs.

    If you include the /IMAGE_PATH=directory-spec qualifier, the
    debugger searches for the .DST file in the specified directory.
    The debugger first tries to translate directory-spec as the
    logical name of a directory search list. If that fails, the
    debugger interprets directory-spec as a directory specification,
    and searches that directory for matching .DSF or .EXE files. A
    .DSF file takes precedence over an .EXE file. The name of the
    .DSF or .EXE file must match the image name.

    If you do not include the /IMAGE_PATH=directory-spec qualifier,
    the debugger looks for the DST file first in the directory
    that contains the dump file. If that fails, the debugger next
    searches directory SYS$SHARE and then directory SYS$MESSAGE. If
    the debugger fails to find a DST file for the image, symbolic
    information available to the debugger is limited to global and
    universal symbol names.

    The debugger checks for link date-time mismatches between the
    dump file image and the DST file and issues a warning if one is
    discovered.

    The parameter dumpfile is the name of the process dump file to be
    analyzed. Note that the process dump file type must be .DMP and
    the DST file type must be either .DSF or .EXE.

    For more information about using SCD, see the VSI OpenVMS System
    Analysis Tools Manual.
