The term problem-oriented languages, if taken literally, is too general to be useful in the taxonomy of programming languages. In its most general meaning, one would have to include any programming language that helps solve problems. Thus, Fortran ( q.v. ) is a problem-oriented language when one solves scientific or ...

This year's ACM Annual Conference will host a unique event in the United States, the Fourth World Computer Chess Championship. ACM began sponsoring computer chess tournaments in 1970. The first world championship was held in Stockholm in 1974. Subsequent world championships were held in Toronto in 1977 and in Linz, ...

Two papers will be presented and a general discussion period will then follow. The panel members are all members of the ACM Computer Chess Committee. The first paper, which appears elsewhere in the Proceedings, is the work of Tony Marsland. It is entitled “A survey of enhancements to the alpha-beta ...

CHESS 4.0, a completely rewritten version of Northwestern University's computer chess program, won its fourth consecutive title in the Fourth U.S. Computer Chess Championship sponsored by the ACM at ACM-73 in Atlanta, Georgia last August. CHESS 4.0 was written by David Slate and Larry Atkin, systems programmers at Northwestern's Vogelback ...

Comprehensive graphics enhancements are proposed for information retrieval systems to facilitate interactive plot generation, 1 modification, manipulation and analysis. Capabilities include dynamic axis scaling, text insertion/deletion, display of plot description, relations, selected data point values and saving/re-calling plots. Controlled by “self-adjusting” graphics software, the package will provide various interactive options ...

One problem facing an academic program in computer and information sciences is how to teach the basic ideas of simulation without being overwhelmed by the requirements of presenting a complex simulation language. It is usually true that the student taking a simulation course has some prior knowledge of computer programming, ...

This paper will review the development of numerical control in the United States and Europe, will summarize the growth of NC programming languages in the United States, and will contrast these developments with current efforts in NC language development and standardization in Western Europe.

The APT (Automatically Programmed Tools) language for numerical control programming is described using the metalinguistic notation introduced in the ALGOL 60 report. Examples of APT usage are included. Presented also are an historical summary of the development of APT and a statement concerning its present status.
