One point about sockets and C on z/OS: most UNIX programs using sockets do NOT expect to get a socket ID of zero. If your C (or other socket program since you can do it in assembler also) is running under MVS side of z/OS and NOT under the UNIX System Services, you CAN get a socket of zero when you attempt to allocate a socket. I am speaking from experience. And sockets do work fine on z/OS whether from the "normal" side or the UNIX side. I cannot speak to CURSES or X11.

The z/OS Communications Server IP Programmer's Guide and Reference manual (e.g. z/OS 1.11 SC31-8787-11) talks a lot about X11 and has a page "X Window System programming considerations" showing how to compile such applications. So if the manuals are to believed, z/OS XL C/C++ should support Curses, X11 and sockets from z/OS UNIX. John, thank you for the reverse X tunnel recipe using ssh. Sounds very secure. Scott, thank you for the tip about how to run the XMing X Server on MS Windows as an alternative to the Cygwin X Server that John has used. Running Java programs on z/OS with their GUI displayed on your workstation sounds neat.

Do you mean that there is an X-Window server using GDDM, or that there is an X-Window client to send GDDM graphics to an X-Server? -- Shmuel (Seymour J.)
