Similarity:

PSTricks is an abbreviation for PostScript Tricks and uses the enormous graphical capabilities of the old programming language PostScript. It is a so-called page code language (PCL) which is distributed since 1984 by Adobe Systems. PostScript is fully Turing compatible and a stack-oriented programming language, like Assembler, Forth, Hewlett Packard pocket calculators, et al. PDF is derived from PostScript, with some important extensions but without the possibility of mathematical calculations. ...

Two-Language, Two-Paradigm Introductory Computing Curriculum Model and its Implementation

Zanev, Vladimir, Radenski, Atanas (2011)

Serdica Journal of Computing

Similarity:

This paper analyzes difficulties with the introduction of object-oriented concepts in introductory computing education and then proposes a two-language, two-paradigm curriculum model that alleviates such difficulties. Our two-language, two-paradigm curriculum model begins with teaching imperative programming using Python programming language, continues with teaching object-oriented computing using Java, and concludes with teaching object-oriented data structures with Java.

A Language for Compositional Programming: A Rationale and Design Език за композиционно програмиране: Обосновка и конструкция

Bantchev, Boyko (2011)

Union of Bulgarian Mathematicians

Similarity:

Бойко Бл. Банчев - Представена е обосновка и описание на език за програмиране в композиционен стил за опитни и учебни цели. Под “композиционен” имаме предвид функционален стил на програмиране, при който пресмятането е йерархия от композиции и прилагания на функции. Един от данновите типове на езика е този на геометричните фигури, които могат да бъдат получавани чрез прости правила за съотнасяне и така също образуват йерархични композиции. Езикът е силно повлиян от GeomLab, но по редица...

Programujeme L-systémy v PostScriptu

Michel Charpentier (2012)

Zpravodaj Československého sdružení uživatelů TeXu

Similarity:

Although we tend to think of PostScript as a file format used to describe graphics, it is in reality a full-fledged programming language with graphical capabilities. Thus, the power of PostScript goes far beyond that of simple vector-graphics formats. All sorts of computations can be programmed, including complex arithmetic calculations. In this paper, we show how to use recursive functions in PostScript to implement a family of rewriting structures known as L-systems. Based on these...
