$REGISTRYW_(Alpha_and_Integrity_servers)

   On Alpha and Integrity server systems, interface to the OpenVMS
   Registry database server.

   The $REGISTRY service supports both asynchronous and synchronous
   operations. For asynchronous completion, use the Registry
   ($REGISTRY) system service.

   For synchronous completion, use the Registry and Wait
   ($REGISTRYW) system service. The $REGISTRYW system service is
   identical to the $REGISTRY system service, except that $REGISTRYW
   returns to the caller after the system completes the requested
   operation. For additional information about system service
   completion, see the Synchronize ($SYNCH) system service.

   This system service is 64-bit compatible.
