Seymour, I meant that an X Server (display window) running on a workstation (such as a PC, Mac or UNIX box) can receive X Window graphics from a z/OS X Client (the application program) that uses GDDM/MVS and the GDDMXD/MVS interface. At least, that's my understanding.
Paul, thank you for the clarification that the original comment (about a possible lack of Curses, X11 and socket support) referred to the IBM XL C/C++ compiler rather than z/OS UNIX. The z/OS XL C/C++ Programming Guide (for example SC09-4765-10 z/OS V1R10.0-V1R11.0) has a page that says it supports Curses under z/OS UNIX, with a link to the z/OS C Curses manual (SA22-7820). A large section in the same Programming Guide "Understanding z/OS UNIX sockets and internetworking" talks about support for the various flavors of sockets with a pointer to the z/OS XL C/C++ Run-Time Library Reference for the exact API. 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. Cheers, dap _____________________________________________________ In <[email protected]>, on 9 April 2012 at 12:08 AM, David Price <[email protected]> said: >Does this imply that X-Windows under z/OS UNIX System Services is >usable It implies that you can run an X-Window (no S) client. >Turning to the z/OS MVS side for a moment, I see that GDDM/MVS >supports X-Windows graphics through the GDDMXD/MVS interface. 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.)
