Hi,

Run[..] is the right command and somthing similar works perfectly fine
on my Linux machine. Have you tried to give your command as

Run["program.exe", "-i oldfile.dat", "-o newfile.dat"]

Are you sure that your program.exe is found? Remember that when using
the commandline from within Mathematica your Paths and Environment
Variables may be different.

Have you checked your return code from Run? Try something simple like

Run["dir"]

and you should get 0 as return value (if this is on Windows the same
return code). When you run a command which does not exist, you should
get a different return code:

In[3]:= Run["forbar"]

Out[3]= 32512

Hope this helps a bit.

Cheers
Patrick
