    We&#39;d need to see you control files, but I suspect the TDEF line is
    causing problems.  I believe this gets set with your first open
    file.  For example, if you open a file and &quot;set t 1&quot;, time will get
    set to some date as defined in that control file.  If the subsequent
    files don&#39;t have this date defined you&#39;ll get the grid coordinate
    error.  You could issue a &quot;set dfile&quot; command to re-set the
    coordinates.<br>

          30z, 36z, 42z... the first one has the right time value, but
