VMS Help ANALYZE, /CRASH_DUMP, /RELEASE, Description  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Use the /RELEASE qualifier to release from the system paging file
    those blocks occupied by a crash dump. Be aware that when you use
    the /RELEASE qualifier, SDA immediately deletes the dump from the
    paging file and allows you no opportunity to analyze its contents.

    When you specify the /RELEASE qualifier in the ANALYZE command,
    do the following:

    1. Use the /CRASH_DUMP qualifier.

    2. Include the name of the system paging file
       (SYS$SYSTEM:PAGEFILE.SYS) as the filespec.

    If you do not specify the system paging file or the specified
    paging file does not contain a dump, SDA displays one of the
    following messages:

    %SDA-E-BLKSNRLSD, no dump blocks in page file to release,
                      or no page file
    %SDA-E-NOTPAGFIL, specified file is not the page file
