An Efficient Algol-60 System for the PDP-8

This document describes an efficient, one-pass Algol-60 compiler designed for the PDP-8. The system translates Algol-60 into an intermediate language for the run-time system, providing faster execution than OS/8 Fortran. The compiler itself is written in Algol and is designed for machines with limited memory, optimizing for small run-time overhead and memory efficiency. The paper details design objectives, the structure of the object code, the compiler implementation, run-time data management, input/output procedures, and performance comparisons.
