  Inter-Process Communications? 
 The Question is:
 
How do I communicate detween tow processes on two machines?
 
 The Answer is :
 
  Typically via a network.
 
  Common network communications protocols include clustering, via IP
  (TCP, UDP, and other IP-based protocols), via Intra-Cluster
  Communications Services (ICC; system services that are part of
  OpenVMS itself), and via DECnet.
 
  For some of the many examples, please see the files in TCPIP$EXAMPLES:
  (if you have TCP/IP Services installed) and SYS$EXAMPLES:DB*.*.
 
  Please acquire and read the OpenVMS Programming Concepts manual, and
  the IP and/or DECnet product documentation.  Please see the OpenVMS
  FAQ for pointers to on-line versions.
