This topic is evocative, even though I really have nothing to say about it. Mike Lesk started, and I believe Brian contributed to, "learn", a program for interactive tutorials about Unix. It was never pushed very far--almost certainly not into typing. But the mention of typing brings to mind the inimitable Fred Grampp--he who pioneered massive white-hat computer cracking. Fred's exploits justified the opening sentence I wrote for Bell Labs' first computer-security task force report, "It is easy and not very risky to pilfer data from Bell Laboratories computers." Among Fred's many distinctive and endearing quirks was the fact that he was a confirmed two-finger typist--proof that typing technique is an insignificant factor in programmer productivity. I thought this would be an excuse to tell another ftg story, but I don't want to repeat myself and a search for "Grampp" in the tuhs archives misses many that have already been told. Have the entries been lost or is the index defective? Doug
