John Lee asks what MIT release DECwindows on VMS corresponds to. The answer is that VMS V5.1 and V5.2 DECwindows corresponds to MIT R2 for XLIB and the Protocol. We incorporated the R3 toolkit intrinsics and the R3 font naming conventions, however. >I reason I need this information is that I have heard that X11R3 is much >better >on the Suns and I would like to upgrade them to X11R3.

What release of X11 is DECWindows (VMS), and >is there any reason why we should not upgrade our Suns? > >--John Lee I can't say what goes on with the Sun stuff, but my guess would be that you would not have much trouble if you did not USE any of the R3 Xlib features on the Sun. In fact it may be MORE compatible because of the font names and intrinsics. As I recall, the Xlib changes are mainly odds and ends of macros that allow access to all the info that comes back from the server setup. (Can someone correct me if I'm wrong). The protocol should not be a problem, although I'm sorry to say that a bug in the VMS server will prevent you from talking from a Sun client to a VMS server whether you upgrade or not. Of course, it would always be safest to upgrade one of your Suns and check it out before you do them all. Burns Fisher VMS DECwindows Development
