Many Thanks to all who replied.
As was pointed out by a couple of people, I _WAS_ swamped by answers.
There were many helpfull answers, two that were wrong (but that is
OK), 1 that asked that I forward the solution. There was one flame and
2 simi-flames. But even they included an answer.

Solution:
Login to machine Y and after Openwindows is running, execute "xhost +".
There are no man pages on xhost, but there is an xman page on it. After
xhost is running, login to machine X and then set the display variable,
Bourne shell or Korn shell (sh or ksh):
DISPLAY=y:0.0 export DISPLAY
C-shell (csh):
setenv DISPLAY y:0.0
After doing this, all Openwindows apps that are on X seem to work fine and
display on Y.
If you logout of machine X, the next time you login, you have to re-set
the DISPLAY variable.
Another way was suggested by Lenny Turetsky.
"From the command line:
program-foo -d host_I'm_really_on:0.0
The `-d' tells it to use the next argument as the name of the machine on
which to display. The 0.0 tells it which screen to display on.
Some programs demand the use of the `-display' rather than `-d' -- check
with the manpages."
There are no man pages for filemgr, but a trial finds that it requires the
-display instead of the -d. There are xman pages, but they don't say
anything about starting it on a remote machine.

There were some script files that were sent, to help automate the process
a little.
Pat Max sent the following:
"...to make it easier I will send you the xon script which came
with X11r4 and the one that came with X11r5. The way you run them is
to type
xon machine command
or
xon machine xterm
and then in the xterm window, type the command. It will run on the
machine and display on yours. When I ran OW a number of years
ago, before I was converted to X11, I used to run the mailtool on
the server that had the mail that way."
Put it in /usr/local/bin and make it 755. I call this on xonr5 and the
other one xon.
X11r5 xonr5
#!/bin/sh

#! /bin/sh
#
# xon: start an X11 client on another host
#
# Runs the given command on another host with $DISPLAY set in the environment.
# Does an xhost to allow access to the other host.
# Xon is very careful not to leave any extra processes waiting
# around on either machine for the client to exit. In order
# to achieve this, csh is used on the remote host and all inputs
# and outputs are redirected to /dev/null.
# The -debug switch allows you to see errors, but doesn't worry about
# leaving extra processes around.
# If the given command starts with "xterm", it adds the arguments
# "-name xterm-$hostname"
# where $hostname is the name of the remote host. This allows
# you to customize your server's xrdb database to set attributes,
# such as the window color, based on the name of remote host.

I have not tried either one, so they may not work.
