For I64 and Alpha linking, directs the linker to mark the cluster
    'cluster-name' with the indicated qualifier keyword value.
    Attributes set by this qualifier are only evaluated by the
    loader. This qualifier is used to build OpenVMS drivers. See
    Writing OpenVMS Alpha Device Drivers in C for guidelines for
    using this qualifier.

 Qualifier Values

       RESIDENT
       Marks the cluster 'cluster-name' as RESIDENT so that the
       segment (I64) or image section (Alpha) created from that
       cluster has the RESIDENT flag set. This will cause the loader
       to map the segment or image section into non-paged memory.

       INITIALIZATION_CODE
       Marks the cluster 'cluster-name' as INITIALIZATION_CODE so
       that the segment (I64) or image section (Alpha) created from
       that cluster has the INITALCOD flag set. The initialization
       code will be executed by the loader. This keyword is
       specifically intended for use with program sections from
       modules SYS$DOINIT and SYS$DRIVER_INIT in STARLET.OLB.
