Thank you Kion Alios ! As a beginner of smalltalk i have realized two things. 1. The main view in smalltalk language is on the " Programming System" ( functions of the Pharo system at all ) You could say : " Open the IDE - check the functions for many days : then start to write Objects with minimal code" 2. In other languages the main view is on the "Syntax and code structure only" ( the systems IDE is minimal styled ) You could say : " Open the IDE - check the function for one day : and start to write code for many days " My next aim is to write a simple program from a practical task. a storage program for items The only information are " what the worker in the company would do with the items ". Therfore i try to make a FLOW CHART with an additional software tool to see the whole Tasks in one view. Then i add the Object names and class names that are corresponding to that tasks ( same name as real ). I would see in practice if this flow chart is a good method for overview. ( Brainstorming - Flowchart ). I dont care of the many functions of the system at this beginning point. Just make ONE simple program , and compile it to an .exe to check on another PC. Regards Hans
