Despite years of work on programming languages, programming is still slow and error-prone. In this paper we describe Macho, a system which combines a natural language parser, a database of code, and an automated debugger to write simple programs from natural language and examples of their correct execution. Adding examples to natural language makes it easier for Macho to actually generate a cor...

Class-based inheritance is normally seen as a basic concept and a prerequisit of object-oriented programming. This position paper states that class-based inheritance is not essential for an object-oriented programming language. Instead of class-based inheritance aggregation, parametrical bindings, and aliasing can be used. Aggregation and parametrical bindings are basic concepts of an object mo...

This paper describes abstractions that have been designed to support distributed programming in the object oriented programming language BETA. The approach is minimalistic in the sense that a goal is to provide the essential building blocks on top of which other distribution related abstractions may be built. This goal is made easier by demanding for type orthogonal persistence and distribution...

A new scheduling agent for existing CIM multi-agent system is being currently developed at the Technical University of Košice. The basic idea is to create an agent based on Scheduling Program developed at the Technical University of Košice. The Scheduling Program was developed in the ECLPS programming language using its constraint logic programming capabilities. It is used for solving JobShop p...

2 Preface This text is an introduction to programming in general, and a guide to programming in the language Oberon in particular. It is primarily oriented towards people who have already acquired some basic knowledge of programming and would like to deepen their understanding in a more structured way. Nevertheless, an introductory chapter is added for the benefit of the beginner, displaying in...

Programming is rapidly becoming an integral part of the basic knowledge that should be possessed by the students of all disciplines, in general, and of engineering and sciences, in particular. This is evident from the fact that the programming courses were included as a part of bachelor’s degree curriculum and soon after, an introductory course of programming has been introduced at high school ...

Selecting a right programming language for introductory CS courses is not an easy task. The pressure to use a commercially successful language can easily be the most significant factor in choosing the language. However, several studies suggest that it is preferable to use language especially designed for teaching. These languages are usually some kind of pseudo languages, defined by the program...

We show how the use of coroutining can lead to a simple but complete foreign language interface between Prolog and imperative programming languages such as C, Pascal or Basic. We show that both explicit and implicit coroutining must be supported. Explicit coroutining is achieved using the freeze/2 predicate. Implementation of the interface is straight-forward. The system has been used in an exp...
