Hello Afaque,

it should be possible if you can invert your problem. If you start the
ruby interpreter from the batch file, you have the variables set.

--8<---test.bat---8<---
SET FOO = "foo"
ruby test.rb
--8<-----------------8<--


--8<---test.rb---8<---
puts ENV['FOO']
--8<-----------------8<--

If you want to use the batch file as some kind of configuration file,
maybe you could revert to a real configuration file. E.g. in yaml.

best regards,
