Re:But how can anyone learn to use mainframes? (Score 3, Funny)

Find them in India. There are thousands of Mainframe programmers. When I joined my first job, I was initially assigned to one mainframe project, which eventually I left. My employer used to have few thousand mainframe programmers. We used to call that office "mainframe factory". Tell you the truth, mainframe brings a large fraction of the revenue of India's leading IT services companies.
