Patrick,
 
Very interesting !
In your script Test.bat, what do the following lines accomplish:
 
first line> @rem =3D = '--Ruby--
line# 16> @rem=20 ';
last line> set TMP_BAT_FILE=3D=20
 
Thanks,

What we've done at my company for = some=20 internal scripts is create a batch file that contains Ruby code, which = in turn=20 creates a temporary batch file which the outer batch file then=20 executes.
ie:  
Test.bat
---
@rem =3D = '--Ruby--
@echo=20 off
if "%TEMP%" =3D=3D "" (
    echo TEMP not=20 set
    goto exit 2>nul
)
SET = ARG=3D%1
if "%1" =3D=3D=20 "" (
    SET ARG=3Dnil
)
set=20 TMP_BAT_FILE=3D%TEMP%\TMPBAT_%RANDOM%.bat

:exec
ruby -x -S = Test.bat=20 %TMP_BAT_FILE% %1 %2 %3
goto endofruby
@rem = ';
#!ruby

# ruby=20 code here
# write out Windows shell commands to the ARGV[0]=20 filename
__END__
:endofruby
@echo off
if exist = %TMP_BAT_FILE% call=20 %TMP_BAT_FILE%
del %TMP_BAT_FILE% 2> nul
set = TMP_BAT_FILE=3D
