I just downloaded and installed Euphoria on my Linux box,
and I've written my first program -- a factorial function.
In my source file, printfact.exu, I have the function
definition, followed by "? factorial (5)". When I enter the
shell command "exu printfact.exu", the answer, 120, is
printed, but then exu enters an interactive mode, printing
out "Press Enter...". I just want it to print the answer and
exit (back to the shell). How do I do this?
Thanks,
Tom Dailey

I don't use Linux and it doesn't happen on a Windows XP machine, but try;
abort(0) -- Returning Successful Completion

Thank you for your suggestion. Unfortunately, adding
"abort(0)" as the final line of the program has no
apparent effect.

Is it warning you at all?
If so, add: }}}
<eucode>without warning</eucode>
{{{
Otherwise, you may have to wait for a Linux guru to come online!

I added "without warning" at the beginning of my source
file, but that had no effect. I guess you're right about
having to wait for an experienced Linux user...
Thanks anyway,
Tom

Hi
Its not a linux thing, I think its just free_console() at the end of the
program.

Chris:
Yes, free_console() caused the program to exit. Unfortunately,
it also erased all traces of my printout. This can't be that
hard! I just want to write a program that prints a result on
the standard output (my Xterm), and then terminates. In
other words, I want to achieve the same effect as if I had
executed a C program in which main() executes printf() and
then exit(). Surely this is possible.

Nope. The Linux version of Euphoria uses ncurses to do all writing to the screen
so you can't have normal command line programs.
