Preface

MicroScript is a visual programming language that runs on the BTRON operating system. In particular, it is suited to the uses below.

Presentations

MicroScript can change window screens one after the other in the manner of a picture story show. You can freely carry out programming for the purpose of making pictures appear, disappear, and move around inside that. Contrivances in which you cause some sort of different operation when you create a button inside a window and click on it can also be embedded.

From these features, MicroScript becomes the most suitable tool for uses where appealing to the visual is efficient, for example, presentations.

Applications for Special Uses

Because MicroScript is a visual programming language, it can very easily carry out screen design, and interactive processing compatible with various operations on the screen can easily be described. Furthermore, because not just operations concerning the top of the screen, but also functions that operate on characters and numerals, and that perform operations are provided in abundance, it is possible to create in a short period of time various types of applications aimed at special uses concerning such things as data input, aggregation, processing, and display. Moreover, it is also possible to describe higher level processing, such as control of external devices through through a serial circuit, or data exchange with a host.

Programming Language

Because MicroScript is a programming language, it is provided with such functions as macro definition, numerical calculation, condition judgment, recursion, procedures, and variables. Furthermore, event driven procedures and multitask description also are possible. These are indispensable when building graphical user interfaces. In MicroScript, we have loaded abundant functions on top of a carefully selected simple mechanism. For that reason, its innards as a language are deep, and as soon as you master it, it can be applied top a very large number of uses.
