The problems of software development for microcomputers are studied through the design and implementation of a simple systems language, called E. E is a descendant of the BCPL family of systems programming languages. Differences between E and its predecessors arise from the design of E as a minimal language, and from the objective of enabling interactive tracing of E programs. A development system for E has been constructed which may operate in a microcomputer with 16K bytes of memory. As well, E programs may be developed using a cross compiler which runs on a large computer system. / Applied Science, Faculty of / Electrical and Computer Engineering, Department of / Unknown

<p> This project is about the design and implementation of a new programming language, Mytran. Two new control statements are implemented in Mytran. Data abstraction is supported through parameterized types or "type constructors".</p> / Thesis / Master of Science (MSc)

Visual scripting languages are used as alternatives to text programming to make coding easier. Visual programming languages provide a structure and a guidance that does not exist in text programming, which should make them easier to code with. Some users do however find that the structure in visual scripting languages makes it cumbersome to code. To find a design of visual scripting that subvert this and has a better user experience than contemporary designs, a prototype of a visual scripting interface was developed using an iterative design and testing cycle. When a final prototype had been developed, it was tested to see how it compared to text programming. From the tests performed, a few teachings were discovered. If-statements that grow perpendicularly to the rest of the code fit more information on the screen at the same time and can feel more natural and easier to parse for some users. Having a help menu with syntax-help makes it so that users do not have to leave the program, which increases programming speed. The visual coding elements in a visual scripting language need to be coloured such that the most important parts are the most visible; otherwise users have a hard time parsing the code. Showing existing variables that are in scope gives the user a good overview of what variables they can use. Having help menus where elements can be clicked to insert them at the user's text cursor reduces the chance of misspelling variables and gives the user confidence in the correctness of the code. Having visual coding elements that can change depending on context or by using toggles can make coding more intuitive and faster. / <p>Examensarbetet är utfört vid Institutionen för teknik och naturvetenskap (ITN) vid Tekniska fakulteten, Linköpings universitet</p>

The goal of this thesis is to develop a procedural terrain height map generator programmable using a Turing complete scripting language. The generator must allow rendering of partial maps by generating arbitrary rectangular region of the map described by any script. The thesis explains why this means the traditional script execution model won't work in this case and proposes a novel two stage model, which executes the scripts in two stages - a simulation stage and a rendering stage.
