Last Updated 2011-06-16 by Paul Green. Moved from Stratus in August 2017.
The Paul Green Multics Collection contains papers written by Paul Green, and programs written by Paul and several other Multicians.
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.
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.
clock_speed.pl1 Multics PL/I program to time the Multics clock builtin; by Paul Green.
copy_bad_mst.pl1 Multics PL/I program to copy a Multics Standard Tape; by Paul Green.
copy_tape.pl1 Stratus-on-Prime PL/I program to copy a tape; by Paul Green.
create_moo_ladder_file.pl1 Stratus program to create the "moo" ladder file.
display_descriptor.pl1 Multics PL/I program to decode a Multics argument descriptor; by Paul Green.
