Hi!
I'd like to suggest an improvment to the "system" call in Euphoria.
It's very nice to use EUPHORIA as a batch super-processor, but is not =
trivial to catch the standard output.
Some of the OS commands (i.e. date) have an alternate command inside EU. =
But user programs have to pass the output via a disk file.
It would be very nice if we could write something like:
myOutput =3D system("Myprog")
where myOutput would be a sequence with the stdout of the called =
program.
So we could write something like
MyEnv =3D system("set")
and find out the names of all defined variables in the environment... I =
can think of many uses.
Jesus.

That is a really nice addition! I'm not sure whether it is possible to
capture the standard output from DOS, but if so, it would be handy indeed.

Tcl/tk works that way...
And is *really* useful.
For instance, you could use Euphoria as a kind of "glue" for executable
programs you don't have the source.
Processing the stdout would allow you to integrate them into an upper
functional block.

And ... dare I say it? ... so does Perl. 
Another functionality area that's not too hard to implement, since I'd
bet that even though Perl's interpreter is no slouch, Euphoria probably
beats it speed-wise.

What would be good is to have a device to redirect system calls
exampe: system "echo %eudir%>EU1:"
MyDirectory=EUPHORIA_DEVICE()
