RunThrough on Windows 2000


Group:

On my Windows 2000 system, I have a 1991 MS-DOS application called
"MKS Toolkit".  It has a Unix "cat" command.  Here's some interesting
results with Mathematica 5.0.

If I use the example in the Mathematica Book, I get ...

In[60]:=
RunThrough ["cat", 123]
Out[60]=
123

after a brief flash of the Mathematica-launched DOS box.

If I embellish this example a bit, I get ...

In[61]:=
RunThrough ["cat", 123+456]
Out[61]=
579

These are not the results I expected, as when this 1991 "cat" is typed
directly into the MKS DOS box I get ...

C:\MKS> cat 123
cat: 123: no such file or directory

and ...

C:\MKS> cat 123+456
cat: 123+456: no such file or directory

I'm baffled.  Does this make sense to anyone?
