     This is odd.  It works fine on our RedHat 9 machines in KDE
environments.  We saw this problem in Solaris machines that do not
seem to handle the single quotes surrounding the command to be
executed.  But other Linux machines seem to require them!

     I suggest that you restore the XASERVERS to its normal form in
$SYSUNIX after copying your version into $SYSLOCAL.   Then the MNJ
will not interfere with your corrections.  Note that UNIXSERVERS also
has this grammar.  I am left not understanding this whole business -
why are quotes required sometimes and apparently forbidden other
times.
