There was the same question in ruby-talk
and the 
answer(http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/68095) is
make test.bat like this:

@rem = '--Ruby--
@echo off
if "%TEMP%" == "" (
    echo TEMP not set
    goto exit 2>nul
)
SET ARG=%1
if "%1" == "" (
    SET ARG=nil
)
set TMP_BAT_FILE=%TEMP%\TMPBAT_%RANDOM%.bat

:exec
ruby -x -S Test.bat %TMP_BAT_FILE% %1 %2 %3
goto endofruby
@rem ';
#!ruby


# ruby code here


# write out Windows shell commands to the ARGV[0] filename
File.open(ARGV[0],"w") { |f|
  f.puts('cd \download')
}
__END__
:endofruby
@echo off
if exist %TMP_BAT_FILE% call %TMP_BAT_FILE%
del %TMP_BAT_FILE% 2> nul
set TMP_BAT_FILE=
