Hi,

Well, I'm runing the program on computer that does not
have cygwin installed.  I just put a copy of the
cygwin1.dll in the windows path. 

My typo, I do have it like this
system("ls -la c:\\mydir >
c:\\mydir\\tmp\\lookup.txt") 

as I mentioned in my post, the same program runs in
other computers running windows xp, just not running
on this particular machine.
