One of the basic limitations of a digital computer is the size of its available memory; an approach that permits the programmer to use a sufficiently large address range can accomplish this objective, assuming that means are provided for automatic execution of the memory-overlay functions.
Program evolution: processes of software change
A Model of Large Program Development
Observations made on the development of OS/360 and its subsequent enhancements and releases are discussed and some modeling approaches to organizing these observations are presented.
Dynamic space-sharing in computer systems
A formalization of relationships between space-sharing, program behavior, and processor efficiency in computer systems is presented to illustrate a possible analytic approach to the investigation of the problems of space- Sharing.
An anomaly in space-time characteristics of certain programs running in a paging machine
The running time of programs in a paging machine generally increases as the store in which programs are constrained to run decreases. Experiment, however, have revealed cases in which the reverse is…
System partitioning and its measure
On-Line Measurement of Paging Behavior by the Multivalued MIN Algorithm
An algorithm is presented that extracts the sequence of minimum memory capacities (MMCs) from the sequence of page references generated by a program as it is executed in a demand paging environment...

To reach a better balance between free innovation and disciplined construction, we must bring an experimental element to software engineering, creating a modifiable and configurable software…
GREENPRINT: A Graphic Representation of Structured Programs
To improve the readability of programs over existing techniques, a new program representation termed GREENPRINT has been developed and is discussed in this paper. GREENPRINTs (the name taken from the…
