"This is extraordinary news for all nerds, computer scientists and the Open Source community: the source code of the MULTICS operating system (Multiplexed Information and Computing Service), the father of UNIX and all modern OSes, has finally been opened [get it here]. Multics was an extremely influential early time-sharing operating system started in 1964 and introduced a large number of new concepts, including dynamic linking and a hierarchical file system. It was extremely powerful, and UNIX can in fact be considered to be a 'simplified' successor to MULTICS (the name 'Unix' is itself a hack on 'Multics'). The last running Multics installation was shut down on October 31, 2000."

PL/I is hardly a difficult language to understand. It's similar to ALGOL in some respects, which eventually led to varieties of Pascal and Modula. Having some knowledge of data languages will help also, but once again, there isn't a whole lot that shouldn't be apparently to those who know C and SQL.
MULTICS was an interesting operating system but it always seemed buggy and unstable. Hopefully, the opening of the source code will help others avoid mistakes with a quick history lesson.
