Redirection of output

Hello all,

how can a windows program detect, whether it's output has been
redirected to a file?

Normally, when I want to see the output of puts(1, ...), I must
add wait_key() or something similar to the code. Then I have the
following code, for instance:

----------------------------------------------------------
include get.e
integer junk

puts(1, "Hello World!\n\n")
puts(2, "Press any key...")
junk = wait_key()
----------------------------------------------------------

When the output is redirected, the statements
   puts(2, "Press any key...")
   junk = wait_key()
are not useful.

It would be very helpful, to have a function for this, so that
the code could be written as:

----------------------------------------------------------
include get.e
integer junk

puts(1, "Hello World!\n\n")
if not output_redirected() then
   puts(2, "Press any key...")
   junk = wait_key()
end if
----------------------------------------------------------

Can anyone help?

Thanks in advance,
   Juergen
