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

    the debugger to complete executing all process specified by the
    previous command before displaying a prompt to accept and execute
    another command.
