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

    (Default) Causes the debugger to trace when a process does an
    image exit. The debugger gains control and displays its prompt
    when the last image of a one-process or multiprocess program
    exits. See also the /ACTIVATING qualifier.
