The APT (Automatically Programmed Tools) language for numerical control programming is described using the metalinguistic notation introduced in the ALGOL 60 report.…
USA participation in an international standard glossary on information processing
A considerable number of glossaries in the area of information processing have been produced in the USA in the last ten years [1, 2]. In some cases the glossaries were…
Report of a visit to discuss common programming languages in Czechoslavakia and Poland, 1963
Early in June 1963 there was a meeting in Berlin [1] of the Subcommittee for Programming Languages, SC5 of TC97, the Technical Committee for Standardization of Computers…
A serial technique to determine minimum paths
The need to determine minimum paths through a maze very often arises in such fields as traffic, transportation, communication and network studies. Computer analysis of…
Recursive programming in Fortran II
An oft-mentioned advantage of ALGOL over FORTRAN is the recursion capability of the former. FORTRAN adherents often belittle this advantage by claiming that all recursive…
Flexible abbreviation of words in a computer language
An increasing number of computer programs are designed to accept and translate a symbolic, English-like language which facilitates communication between the user and the…
An error-correcting parse algorithm
During the past few years, research into so-called “Syntax Directed Compiler” and “Compiler Compiler” techniques [1, 2, 3, 4, 5, 6] has given hope…
MADCAP is a programming language admitting subscripts, superscripts and certain forms of displayed formulas. The basic implementation of this language was described in a…
Optimizing bit-time computer simulation
A major component of a bit-time computer simulation program is the Boolean compiler. The compiler accepts the Boolean functions representing the simulated computer's…
Length of strings for a merge sort
Detailed statistics are given on the length of maximal sorted strings which result from the first (internal sort) phase of a merge sort onto tapes. It is shown that the…
Coding clinical laboratory data for automatic storage and retrieval
A series of clinical laboratory codes have been developed to accept and store urinalysis, blood chemistry, and hematology test results for automatic data processing. The…
Application of IBM 1620 EDP methods to the calculation of the formulation constants of complex ions
In the course of our work on the physical chemistry of histamine and related compounds, we have done extensive work involving potentiometric titration of systems of…
