I've been having some minor problems with the System() call (dos.lib) in
AmigaDOS 2.0.  It works fine when I specify input/output streams that
are taken from the DOS Input() && Output() calls.

But when I open a filehandle to the current window

ie.

file = Open("*",MODE_OLDFILE)

and pass file to System() to specify input/output, then none of the programs
in the c: directory (eg. dir, list, copy) function correctly.

ie.
	System("copy",tagarray);

brings the system down in a big way.  Is there something different about
the C= c: directory programs that means they can't take a filehandle to
* as input?  I would like to use this for my own shell running in it's own
window, but the C= c: directory programs don't seem to work when passed
a filehandle to a CON: window for i/o either....

Am I doing something wrong?
