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

 using file_specification BUT it does NOT appear to match with file_
 specification

    Facility: DEBUG, VMS Debugger

    Explanation: The debugger is pulling debug symbol information
    for an image from the image DSF file BUT the link time in the
    image header for the DSF does NOT match with the image EXE.
    This means there may be symbolic and/or source line correlation
    misinterpretations or omissions.

    User Action: Verify that, if defined, the dbg$image_dsf_path is
    set up correctly. Verify that your DSF was created by the same
    link that created your image EXE.
