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

 no source directory list in effect for path_name

    Facility: DEBUG, VMS Debugger

    Explanation: The debugger command CANCEL SOURCE/MODULE=path_name
    failed because there is no source directory search list in effect
    for module path_name.

    User Action: This is an informational message. However, if the
    wrong module was specified, the command should be re-entered with
    the correct name.
