Abstract
The MIX computer system is a machine-independent software system, written in FORTRAN IV, giving users the ability to assemble and execute programs written for the MIX computer, as defined in D. E. Knuth in The Art of Computer Programming. The system consists of four essentially independent major subsystems: the control system, the interpreter, the assembler, and the loader. The system runs as a single job under the operating system of the host machine, but the system has its own control statements to allow batching of MIX jobs within a single host machine job.
