XUIS (or whatever legal decides we can call it) has been
program announced and will be in field test "real soon".
Note that there are a number of restrictions (like no
DOP or QIO interfaces, no VWS kernel applications and/or
terminal emulations... etc).
There are also performance and accuracy issues.
Stay tuned. We'll let you know when there is something to
play with.

Because of the amount of mail I've gotten asking about XUIS, I hacked
up a short blurb explaining it. Enjoy.
Fred Kleinsorge, XUIS development
XUIS Overview
XUIS is a runtime library for VMS which implements the UIS
application program interface using X11 as the graphics subsystem.
It will provide a mechanism to run applications developed for the
VWS window system on DECwindows workstations. It will do this by
making Xlib calls (the low-level interface for DECwindows) rather
than directly accessing the graphics hardware. It will allow most
UIS applications to execute without the need to recompile or relink.
The XUIS library is intended as both a long- and short-term
means to migrate users from VWS to DECwindows. The short-term goal
is to move VWS/VMS users quickly to DECwindows. While the long-term
goal is to allow many applications to never require any rewriting,
or to require only minor changes. XUIS protects the customers
investment in both UIS and VMS while providing access to the
DECwindows desktop environment and network transparent windowing.
XUIS provides relative device independence to UIS allowing UIS
applications to execute on the VS3520/40 and next generation
graphics hardware only available with DECwindows. In addition, it
provides remote UIS facilities, allowing a UIS application to
display and input on non-VAX and non-VMS DECwindows compatable
hardware (the UIS client must still run on a VAX/VMS system).
XUIS also provides the UIS virtual display concept to
DECwindows users. A single virtual display can control windows on
up to 16 workstations, allowing a single output operation to draw on
multiple workstations. XUIS brings UIS features such as window
integrity (guaranteed backing-store), world-coordinates, graphic
text, display lists and hardcopy output to the DECwindows
environment.
XUIS is a sharable image which implements a subset of the UIS
runtime library interface. XUIS will allow customization on a
per-image, per-process and system-wide basis over performance and
accuracy of the emulation.
XUIS cannot or will not provide support for:
o The DOP interface or direct monochrome bitmap access.
o The Video QIO interface.
o Digitizer (CREATE_TB) support.
o The VWS "look and feel".
o Access from kernel-mode.
o The VWS terminal emulators.
o Applications that depend on specific UIS quirks or bugs which
are not feasible to reproduce.
Page 2
o Applications which depend on the results of any function not
implemented in XUIS and any use of any undocumented or
unsupported UIS features.
XUIS is PROGRAM ANNOUNCED and has been shown at DECUS. It is
not currently available to internal or external users. Internal
kits will be provided when the software is in a relatively complete
and stable condition. Field Test is currently scheduled for early
Q3, inquiries should be directed to the product Larry Villandry.
Performance cannot be commented on at this time. Keep in mind:
o Emulations are usually at least slightly slower than the native
implementation. Comparison is only valid between UIS and XUIS
and not with native DECwindows. UIS provides a much
higher-level graphic interface than Xlib.
o Client side backing store (when enabled) requires all operations
to be sent to the server twice. Even with optimizations such as
pixmap copy areas onscreen, much more work is done.
o UIS application behavior which was acceptable such as frequent
attribute changing may cause non-optimal X11 performance. X11
is a poor performer when drawing operations cannot be collapsed
and compressed, attribute changing reduces the Xlib and Server
optimizations.
o Graphic Text must be done on the client and cannot take
advantage of any hardware assist.

| 1812.4 | will it run SIGHT? | YIELD::HARRIS | | Tue Jan 09 1990 20:10 | 7 |
| Will XUIS, or what ever it will be called be able to run SIGHT.
My group has created many charts/drawings using sight and have to
modify them often. We currently switch windowing systems to go from
DW to VWS(UIS) in order to use SIGHT. Also any idea when a field test
version might be available.

| "VMS/UISX" is just about to go to FT. Kit's should be available at the
end of this week.
The "acid test" is SIGHT, it abuses the crap out of UIS. We have
are at a point where almost all of SIGHT works without any problem.
We plan on being able to support both SIGHT as well as RENDER on
non-UIS VMS systems.

Sorry, there should be an IFT kit made available in the next day
or so. Keep your eyes peeled.
Due to a sudden reorganization (UIS is being transfered back from
SWS/E to Worksystems Engineering!), VWS V4.3 FT1 (aka UISX) has
has been put on hold for a while.

Make that IFT. Still not FT1. Check the VWSENG::UISX notesfile.

Fred,
good work! Citibank will thank you guys for XUIS! Citibank
bought about 1000 VS2000s to develop UIS-based applications
for traders a few years back.

| Citibank is working to re-write those applications from UIS to
DECwindows.
I really hope that no one attempts to distribute pre-release versions
of these products to customers without approval from product management
and the ability to support XUIS without recourse to engineering

Information on UISX (renamed because XUIS is legally indistiguishable
from XUI) can be found in the VWSENG::UISX notesfile. UISX FT1 kits
are shipping this morning, the FT1 kit will be put into
VWSENG::UISX$FT1:UISX010.* in a few minutes.
The latest version of UISX is suprisingly fast... (we did a little
optimization with backing store) I think people will like it.
Citicorp has a problem: WCDRIVER. They took a early version of the
VT100 emulator and modified it to function as a color terminal... this
will not work - no inner-mode access is provided by Xlib.
