Advice for Older Entry-Level Programers?

jmorse asks: "My uncle recently shut down his manufacturing business and is considering entering the job market as an entry level programmer. He's done a lot of ad-hoc programming in several languages to fulfill his business' needs, but has never held a job as a programmer or software engineer. I know it's a tough time to be looking for a programming job, especially when there are so many unemployed younger people who would gladly put in long hours. What advice do slashdotters have for an older guy just getting started?"
