Alan,
Thanks for taking the time for writing such a comprehensive response
I shall certainly investigate what I originally had planned on doing.
If you really are going to do that, just be aware you need to test it on all
the devices / emulators you use in your shop. In theory you should also
first use DSM to verify the device reports that it supports WEA orders. I
also looked it up and I remember incorrectly what WEA stands for -- it is
Write Extended Attribute. Here is a link to the page in the 5494 Functions

but you'll want to prefix that with a Set Buffer Address order (SBA) to set
the row and col position to be modified. You can change not only the
highlight / reverse image / underline status, but the color of each
individual character as well.
I remembered there was also an article once I how to do this, so I searched
for it. You may find this helpful:

I also remember another article which I'm not finding online -- I think it
was in whatever iSeriesNetwork was called at the time in the 90's, and was
titled something like "Colour Me RPG". But searching their archives for
various phrases which should have been in the article, I'm not finding it
now.
