Presented in this paper is a technique for determining the relative effects of the internal speed of the computer and the speed of the input-output units upon the overall speed of the system. Equations are derived which permit …

In January of 1960, the late Hans J. Maehly completed a summary of approximations to the elementary functions for the CDC-1604 computer. The approximations and techniques suggested by Maehly are equally applicable to the second …

Techniques are developed for manipulating bits using only FORTRAN II. These techniques allow individual bits to be tested, certain fields to be shifted, and numbers coded in BCD to be converted to Binary.

The United States Military Academy is faced with the situation whereby 700 cadets may

in a single subject prepare computer programs

in class one day and get their solutions in the form of a computer runoff at their next class …

I was so impressed and pleased by RDNUM, A. Hassitt's General-Purpose Input Routine [

Comm. ACM 7, 6 (June 1964), 350-355], that I have transliterated it into FORTRAN II for the IBM 7094. In doing this I stumbled across solutions …

In simulating the operation of a large storage computer on the IBM 7094, a technique was developed whereby sections of the computer memory which were stored on magnetic tape (IBM 729 Mod II tape drive) could be rewritten without …

Tests of significance based on analysis of variance calculations often require the determination of the probabilities of obtaining values of

F greater than those arising from the analysis. These probabilities are customarily

A few remarks are given on the relations between syntax and semantics in the programming languages.
The aim is to point out that, it is true that the grammar of a contex-free language should be conceived not only as a strings …

The very generality of a language like ALGOL renders it inefficient when a number of programs have to be written all dealing with a fairly narrow range of problems. This can be largely overcome by the construction of a package …
