In General

Welcome to the Introduction to "Fraktal SAS Programming".

The pages provided here are intended to serve as guidelines for Beginners in SAS Based Reporting from Database Tables.

Why "Fraktal"? Start this movie on measurement of coast lines by using Fractals at 16:40 (German audio)

We are using the term "Fraktal" with a "k" here to emphasize, that the programming concept introduced is derived from Fractal Geometry in Mathematics but not identical to it.

Fraktal SAS Programming is considered to be "fractal" because the program archtitecture is suggested to use minimized i.e. smallest scale modules to comprise the implementation from. Unlike fractal curves segments, e.g. used in coast line measurement, the module size meets a lower limit introduced by syntactic properties. Nevertheless, the module size possible will range between a few lines and very few screen pages. Overall size of a module will very rarely reach 100 lines of code. This includes declares, communication and documentation as well as logic like loops and branches.

To make these guidelines compatible with the subject they present, the structure is likewise modularized to a maximum: It is comprised from half-page text slides, making tiny lessons that are easily taken one by one.
