I'm trying to get the return value of a ruby script in cmd.exe. The ruby script will return -1 if exception is caught and 0 if success.

rescue Exception => ex
  puts ex.message
  returnvalue = -1
else
  returnvalue = 0
ensure
  puts returnvalue

in the cmd batch, calling the script using ruby.exe

ruby tt.rb 1 %1

But I'm not able to retreive the returnvalue in the cmd batch file (e.g. using %errorlevel%). Is there any way to do this?

thanks!
