Getting uwm running under VMS DECwindows was very easy, once I got past one big stumbling
block:  The code is sloppy about using free() when it should use Xfree().

Also, I did not bother trying to make spawning subprocesses (so that one can start
applications via the uwm menu interface) work.  I just wanted to replace the DECwindows
window manager.

                                         - Ken

    Can I get a pointer to it?

This version of UWM is now available at:

  VINO::BORDEAUX:[WITHROW.PUBLIC]UWM.SAVZ

This is a compressed backup saveset.  It contains the sources and executable
for the UWM window manager.  As noted in .1, it is currently unable to
perform subprocess things, such as starting up decterms.  Either Mr. Ballou
or myself may rectify this shortcomming in the future.

I have found this version to be quite reliable, and certainly more reliable
than PCX$UWM, available elsewhere.  PCX$UWM, however, IS able to perform
subprocess things.

I hope you've told the PCSG folks what the problems are :-)  After all, PCX$UWM
is going to be the one customers see...

    Gee, you know you've been spending too much time in Notes when you've
    forgotten which notes you've responded to.  Robert, my thanks for the
    pointer that you posted in RDVAX::X bringing me back here. 

    Now, a silly naive question.  How does one uncompress the saveset?

     I have a copy of LZDCMP at
     
        ZFC::ZFC$DISK1:[PUBLIC.LZDCMP]LZDCMP.EXE
     
     I'm not sure exactly what arguments you would give it,
     though.

    Thanks Dan.  You and one other (via MAIL) got this to me at about the
    same time.  The documentation that I have for LZDCMP follows.

    Many thanks gang.  I've got the code and am happily building it now.

        1  File Decompression



                                   **********

        NAME:   lzdcmp -- File Decompression

        SYNOPSIS:

                lzdcmp [-options] [infile [outfile]]

        DESCRIPTION:

                lzdcmp decompresses files  compressed  by  lzcomp.   The
                documentation   for  lzcomp  describes  the  process  in
                greater detail.

                Options may be given in either case.

                -B      Output file is "binary", not text.  (Ignored  in
                        VMS  private  mode.)  On  VMS,  this generates a
                        stream file without carriage-control attributes.
                        On Decus C systems, it generates a "fixed block,
                        512 byte record" file.  It is unneeded on Unix.

                -F      Output file is "fixed block, 512 bytes." This is
                        used  only  by  VMS for reading files created by
                        Unix  compress  or  by  "export"  mode.   It  is
                        identical to binary on Decus C.

                -X 3    To read files compressed by an old Unix  version
                        that doesn't generate header records.

                -V val  Verbose (print  status  messages  and  debugging
                        information).   The  value selects the amount of
                        verbosity.  See  the  lzcomp  documentation  for
                        details.

                VMS COMMAND LANGUAGE INTERFACE:

                        In addition to the  above  (Unix-style)  command
                        line  interface,  lzcomp  supports a VMS command
                        line  interface.   The  following  options   are
                        available:

                        /EXPORT=(VMS, UNIX, HEADER)
                                                                          Page 2
        lzdcmp  File Decompression


                        /MODE=(TEXT, BINARY, FIXED)

                        /SHOW=(ALL, PROGRESS, STATISTICS, FDL,
                                        DEBUG, DEBUG_SERIOUS, DEBUG_IO)

                VMS PRIVATE MODE:

                        If the file was compressed in VMS private  mode,
                        all  information  needed to reconstruct the file
                        is stored in the compressed file, using the  VMS
                        run-time  library FDL routines.  This means that
                        the expanded file will have the  same  name  and
                        directory  location  it  had originally.  If the
                        directory structure does not exist (for example,
                        because  you  have  moved the compressed file to
                        another machine), you must  specify  the  second
                        argument to lzdcmp to specify the file name.

I think it is due the the fact that the server resets itself when
the last connection is terminated.

When you kill the DECW window manager, that is the only connection the
servier has, so it resets.

This causes the properties that DECW$Loginout stuffed on the root window
to be trashed, including the security permissions, and probably other
stuff needed to get things running properly.

When you go to run uwm, or other applications, they won't talk to the server
properly.

I figured this out when the screen flashed each time an application tried to
fire up and then gave up (and the server reset).

The fix was simple. Fire up an application and wait a while for it to
connect to the server BEFORE killing the DECW window manager.

I hope the support for alternate window managers will be a lot better
in decwindows V2 on VMS. The Ultrix folks got it right.

I think I tried to start UWM BEFORE killing the DECW WM and got no joy, but
I'll try that again, plus starting some other application.  I'd prefer to have
the UWM running BEFORE I start any apps because the window dressing added by
DECW$WM causes things to be placed incorrectly on the screen (compared
to UWM).

You can say that again, brother!

Robert,

It can't be the DECW WM...It has to be some other non-WM client.  The
server won't let two window managers run at the same time, so you'll
get a different error.

Try starting up your banner first, then Kill DECW WM, then start UWM.

Regards,

           == ken miller ==

     If the application that gets started up first isn't
     positioned where you want it (because of the difference in
     the window manager decorations), then start up an application
     like "Hello world" that you aren't going to keep around.

Actually, starting the UWM first, and the kinning the DECW wm *almost*
works.  UWM runs, and can move windows and stuff, but it doesn't bring
up menus, perhaps because it is confused about what the root window is
or someting.

> Try starting up your banner first, then Kill DECW WM, then start UWM.

That works.

The version of UWM on VINO (as listed in previous replys) now has
subprocess capabilitys, including the ability to create decterms.
Please read the file VMS_CHANGES.TXT in the saveset.

A known bug is that UWM should really put up the "watch" cursor
(and probably grab the server too) when it is creating the decterm,
since that takes a few seconds.  I havn't figgured out how to do that
yet.

What are the exact arguments require with lzdcmp to decompress

VINO::BORDEAUX:[WITHROW.PUBLIC]UWM.SAVZ for VMS?

What specific command did you get to work?

I got lzdcmp.  I define a foreign command.  And I type

$ lzdcmp uwm.savz uwm.exe

It  finishes and when I type run uwm, i get

%DCL-W-ACTIMAGE, error activating image UWM
-CLI-E-IMGNAME, image file $1$DUA25:[SYS0.SYSCOMMON.][SYSEXE]UWM.EXE;4
-IMGACT-F-BADHDR, an error was discovered in the image header

I've tried various other args (-B, etc.) to no avail.  What's the secret
code word!

Please read 275.3 again (carefully).  UWM.SAVZ is a compressed BACKUP SAVESET.
After you do your

	$ lzdcmp uwm.savz uwm.sav
                              ^^^

do a

	$ backup/list uwm.sav/save

I'm all set now, thanks.

Does anyone have a "current" working version of xterm for VMS?

    
    Try Andy Vesper (3D::VESPER), I know he was tinkering with a highly
    modified xterm.
    
    

 I know uwm can put the name of an icon in the icon symbol but can't fiqure
out how?

I think you can only get the actual ICON, or the name if there is no
icon.  I dont think you can get both, if that is what you wanted...

I know some of you have gotten this to work, but I can't get it to work
on my workstation.  It starts up and then quits without doing anything.
I havn't yet turned on accounting to figgure out why.  Can you tell me how
you do it, or refer me to the correct note here.  I couldn't find the info.
