  Hi Alan,

  Thank you for your attention and kudos to your effort in the list and
the work of all developers.

  Ok, I have played with those routines and I have arrived to an
approach that looks simple enough.

  I called 'plenv' with "axis" parameter equal -2 and them called the
'plbox':

  call plbox("bcmst", 0.0_plflt, 0, "bcnstv", 0.0_plflt, 0)
    (I still have to fully understand the alphabet soup)

  It seems to do what I have expected.   To put the labels where I
wanted I added three calls to 'plmtex' as in the attached code. (Yet
Another Change On x00f.f90)

  I keep thinking that the fact that inverting "ymin" and "ymax" in the
'plenv' call will invert the Y axis.  That is, it is a (desirable IMHO)
feature and not a bug that the developers decide to "fix". ;)

  I think I can live with this.

  I am picky enough to be a manual reader.  ;)

  Ok, I think we can proceed to the remaining questions.
