I didn't want to come across rude there - I can't tell if the intention is
that the color style code is to be dropped or not.

Anyways, the reason I connect the problem with color style is that only
if the color style sheet file is in place, and the program is configured
for color styles, do I see the problem.

In Sun's dbx, the new subcommand is 

check -all

The help for check mentions a -frame <n> and -match <m> but I have
no idea what purpose they serve.

Well, it doesn't solve all the problems - the color-style enabled code
still doesn't do the status line correctly if no style sheet is present
(for instance, right now it says:

-more- http://homepage/projects/source/usenet/rasters/B5/Calendars/ÿÿÿÿÿÿÿÿÿÿÿÿÿ

However, _with_ a style sheet in place, things now appear to be working!
I checked the trace file and all those x'FF' characters are gone.

Now we just need to fix up the case where no style sheet is present.

 just ran it under dbx with -trace and the memory checking on.  Ah ha!  Here
we goetting http://homepage/home/lwv26/.parms/home.html
