there shouldn't be, according to iso and posix c.  you can always do something
like:

   harp:~ > cat a.rb
   def csh_system cmd
     pipe = IO::popen 'csh', 'r+'
     pipe.puts cmd
     pipe.close_write
     buf = pipe.read
     pipe.close_read
     status = $?.exitstatus
     raise SystemCallError::new(status), cmd unless status == 0
     buf
   end

   stdout = csh_system 'echo 42'
   p stdout


   harp:~ > ruby a.rb
   "42\n"


i used to have csh interface in session, but took it out due to some issues
with stdout/stderr separation...

cheers.
