The Abort PPL$ Participation routine ends the caller's
    participation in the application "prematurely"-that is, at some
    time before the caller actually completes its execution.

 flags

    OpenVMS usage mask_longword
    type          longword (unsigned)
    access        read only
    mechanism     by reference
    Bit mask specifying options for terminating access to PPL$. The
    flags argument is the address of a longword bit mask containing
    the flag. The flags argument accepts the following value:

    PPL$M_STOP_        Terminates all subordinates created by
    CHILDREN           the caller in addition to terminating the
                       caller itself. (PPL$ makes no effort to
                       delete subordinates at process termination
                       in the absence of a call to this routine
                       specifying this flag value, but note that an
                       OpenVMS subprocess is deleted when the parent
                       terminates.)
