There are 2 ways to do this. The first easy (and hacked) method
uses system(). The second (more compicated) method uses C calls to
do screen io directly and bypass ncurses.

For the first method, you can just copy this procedure:

procedure echo_puts(sequence s)
system("echo -e "&s, 2)
free_console()
end procedure

This will use the command echo to show data on the screen
(free_console(),
which is in dll.e, is needed to avoid the "Press Enter ..." prompt
which comes up at the end of any Linux Euphoria program).

For the second method, you can use C calls to glibc directly to
show your information. I have already done this and instead of
explaining
how to do it, I will make an announcement to this list when I have
placed
the library on my download site.
