The desktop points descriptor 2 at the rs232 port by default, but you're free
to point it anywhere you want. The MWC runtime code treats descriptor 2 as
stderr, and as such it's usually directed to the console. Of course, none of
this matters if you use Fforce. (Actually, there are 3 variants of the MWC
startup - 1 for desk accessories, 1 for GEM .PRGs, and one for TOS/command line
oriented programs. The default is TOS style, which remaps descriptor 2. That's
what I used for Larn. In actuality, it's the Mark Williams shell that does
the redirection, but that's also beside the point. [The *point* is that you
*can* redirect them and you need to, for the requested purpose.])
