OP's pretty clearly not a seasoned programmer or he would know the difference between a program and an operating system. Very likely he would know the difference between a batch language and a scripting or programming language even.
He's coming from Windoze. I've encountered a number of people like him. They usually have 10+ years of Windoze working at a small company, usually as the #2 or #3 IT person there. They believe that .bat files are the ultimate in user written programs, that .exe files can only be produced by mega corporations, and have not a bit of understanding of programs, operating systems, or other "advanced" concepts.
Just be glad he's starting to break out of this and learn something new. What I'm wondering is how his company ended up with a "Sun machine" and what person put him on that project.
