Subj:	Unmanageable windows under DECW Motif V1.1

After upgrading to DECwindows Motif V1.1, I was able to create DECterm windows,
but I couldn't start the Motif Window Manager and clock.  This probably applies
to other DECwindow applications, but I didn't test them.

One of the major differences between DECwindows Motif V1.1 and previous
versions is that the Session Manager starts all processes up as detached
processes instead of subprocesses.  This means that the processes execute
the system's SYLOGIN.COM and the user's LOGIN.COM.  Buried in the 170 pages of
release notes on page 1-27 is a description of the above along with an
example command procedure which should be placed in SYLOGIN.  I found adding
this code necessary to skip around commands which refine SYS$OUTPUT or require
terminal input.  This code is not an exact copy of what is supplied in the
manual.

$! Check if in interactive mode
$ If (F$Mode() .Eqs. "INTERACTIVE")
$ Then
$!
$!  Exit if not a terminal device (from VMS 5.1 to 5.4 release notes?)
$   If (.Not. F$Getdvi("Sys$Output:", "TRM")) Then Exit
$!
$!  Exit if this is a DECwindows display device or a mailbox device.
$   Terminal = F$Trnlnm("TT")
$   TL = F$Length(Terminal)
$   If ((F$Locate("WSA", Terminal) .Ne. TL) .Or. -
    (F$Locate("MBA", Terminal) .Ne. TL)) Then Exit
$!
$!  Interactive commands go here
  .....
$ EndIf

DECterms under Motif V1.1 use quotas from the SYSUAF instead of using quotas
from the Sysgen PQL parameters.  Reference section 1.4.5.3 in the release
notes.  You should raise SYSUAF parameters to the minimum values specified
below.  If you are creating a large number of DECterms, say on a VAXcluster
Console System, some of these quotas must be raised much higher.

PRCLM     8 to 20
JTQUOTA   1024
ASTLM     200
FILLM     100
DIOLM     200
BIOLM     200
ENQLM     200
BYTLM     32768
WSEXTENT  8192
PGFLQUOTA 37768

Motif V1.1 includes several of the X11R4 MIT utilities including XMODMAP which
is used to remap keyboards and XWD which is used to perform X-window screen
dumps.  Wow!  Now VMS has the same capabilities as most Unix systems.  Don't
take me wrong.  I wish these utilities would have been provided in the first
release of Motif.
