Weeeellllllll...... There IS a "Sockets API" for CICS, provided by the TCPIP (nka Communications Server for z/OS) product, but you'd have to write your own code to exploit it. But for "display devices" (tubes and printers) CICS speaks mainly 3270 datastream and SCS datastreams, and communicates with those kinds of devices via VTAM. Now, VTAM speaks to TCPIP when TCPIP speaks tn3270, and most "modern" tn3270 clients can emulate printers as well as tubes. > Then, why does everybody still the VPS component (or > equivalent) for CICS? Because it's easier and more flexible than tn3270? > Again, can somebody point me to the documentation?
