Re. the "X" marker...

["M.W. Poirier" poirmw@xxxxxxxx]

  It may have something to do with the amount of RAM one has,
  plus the way this RAM is configured, for I have never seen
  this "X" on my machine. I do have a large amount of RAM.

  On a completely different matter, does anyone remember the
  U2 command that produces this sort of file (see below); The
  periods are hard RETURNs. I seem to recall that it was a U2
  routine created by Carl, but I could be wrong. My problem
  is that search as hard as I will, I cannot find the routine
  in question. It likely is one of the log-like or diary-like
  routines. I tried them and none were like what you see below.
  In advance, thank you for your help.
