You didn't say if you're using Linux or Win32 but you could add these lines to
the top of your code ...

include machine.e
if platform() > 2 then
    -- Linux, Unix
    crash_file("/dev/tty")
else
    -- DOS, Win32
    crash_file("con:")
end if
crash_message(" ** PROGRAM CRASHED **")

include machine.e
object IsDebugMode
IsDebugMode = getenv("DEBUGMODE")
if equal(IsDebugMode, "on") then
    if platform() > 2 then
        crash_file("/dev/tty")
    else
        crash_file("con:")
    end if
    crash_message(" ** PROGRAM CRASHED ** at ")
end if

Then run the script with 
(windows)
  SET DEBUGMODE=on 

or
(bash)
  DEBUGMODE=on; export DEBUGMODE

to get the messages on screen. Set it 'off' (or don't set it) to get the ex.err
file instead.

Hell I had to try it before going to bed. No joy!. I guess that I mis-spoke.
I want to see the error message on my web browser -- that's what I meant
when I said that I wanted to redirect the errors to the screen. Sorry about
that!
Your code *must* be working because when I check ex.err after a syntax error,
the error is *not* recorded there -- because it's being redirected. Anyway,
I going to get some shut-eye. Later...

That's exactly where i want the error messages sent to. ;)
