Abstract:
The paper discusses the application of modern programmable pocket calculators (PPG) in the analysis of marketing data. It first shows the main difference of the two basic 'languages' of programmable pocket calculators, viz. Reverse Polish Rotation (RPR) advocated by Hewlett- Packard and the natural 'Algebraic Operating System' (AOS) by Texas Instruments. Then the paper explains Solid State Software libraries containing the equivalent of a 25 card library in one small module not greater than a postage stamp.
