Documentation problems: ALGOL 60
In presenting the following notes I wish to make it clear that they express only my private views. Thus although these views naturally have been greatly influenced by the…
The documentation of COMIT reflects the conviction that adequate user manuals are as much a part of a successful problem-oriented language system as is the compiler…
“The FORTRAN language is intended to be capable of expressing any problem of numerical computation. In particular, it deals easily with problems containing large…
IPL-V (Information Processing Language-V) is a programming language for list processing and symbol manipulation. It is the fifth of a series of programming languages that…
Addressing an array Yi in k-dimensions by Fortran for analysis of variance
In analysis of variance and covariance of data in factorial designs, multidimensional arrays are the rule rather than the exception. The 1620 FORTRAN language is severely…
A variant method of file searching
Trapping an instruction which cannot normally be trapped can be worthwhile, particularly when an existing program is to be revised. However, under those circumstances one…
The following is an account of current documentation on the NELIAC Language.
Certifications of algorithms 117 and 118 magic square (odd and even orders)2
The proof of the non-existence of a phrase structure grammar for ALGOL 60 by Robert W. Floyd [Comm. ACM 5 (Sept. 1962)] depends on the assumption that a syntactically…
A computational extension of the variate difference method
Presented here is a computational extension of the variate difference method as developed by G. Tintner [1].
An interative factorization techniques for polynomials
An iterative technique is displayed whereby factors of arbitrary degree can be found for polynomials in one variable. Convergence is shown to occur always if a certain…
Significance arithmetic on a digital computer
The 7090 at NYU has been modified to include a “Significance Mode” of operation which is intended to facilitate the identification of significant bits in the…
RECOL—a retrieval command language
An interrogation scheme is described for the retrieval and manipulation of data file records. The language of the interrogation scheme allows for selecting file records…
Everyman’s information retrieval system
The information retrieval problem whose solution is presented here was posed by a technical library with limited budget and personnel. The solution, however, is quite…
