Miscellaneous bundles of notes and routines, all in Strachey's hand, some dated December 1970-January 1971, on the design and implementation of the 'Stream Compiler' which was a new compiler for BCPL to run on the P.R.G.'s Modular One System. The work was being done by one of Strachey's D.Phil. students (Alan C. Bamford) under his direction.
