The Paul Green Multics Collection contains papers written by Paul Green, and programs written by Paul and several other Multicians.

Papers

My paper "Multics Virtual Memory: Tutorial and Reflections" is available.

My 1973 MIT S.B. thesis "An implementation of SEAL on Multics" is available. 93MB PDF. This thesis describes the implementation of a code generator for the Seal language on Multics. The implementation developed extensive error handling techniques for both the code generator itself, and the Seal programs it compiles.

Programs

A few sample PL/I programs are available that show a few random examples of Multics user-level code.

case.pl1 Multics PL/I program to implement a "case" active function; by Paul Green.
