I must have been unclear with my last message: my system definately
does support color. All the various installations use ncurses, and all are in
glorious color on a text screen.

Euphoria, however, bombs whenever you try a text_color() or bk_color()
function. EXU is looking for a routine "wcolor_set."  which is not defined. The
reason being, as far as I can tell, is that wcolor_set  is only available with
ncurses 5.0 which comes with RedHat. All the other versions of Linux  that I
have (SuSE 6.1, Slack 4.0) only refer to wcolor_set as a "prototype" for future
use.

Two things seem obvious:
1. I will have to update ncurses to 5.0 (and hope it doesn't break anything) in
   order to get Euphoria to work.
2. Color text is possible without the use of wcolor_set - using some older,
   more universally available ncurses call.
