The Revert to the Handler of the Routine Activator routine
    deletes the condition handler established by LIB$ESTABLISH by
    clearing the address pointing to the condition handler from the
    activated routine's stack frame.

    This routine is not available to native OpenVMS Alpha and I64
    programs but is recognized and handled appropriately by most VSI
    high-level language compilers.
