hahaha I have never thought of that side effect concerning the use of the variables...! :) Thank you all for your enlightening opinions.

Dear all, I am rather new to the exciting world of software development (i do not consider myself a developer but merely a visitor in the field) and have some fundamental questions to express in order to make things strait in my mind. I would like someone to answer the general steps in developing an application. In my mind the steps would go something like: 1. Analyzing the needs of the solution and prepare any relevant documentation on the to-do stuff. 2. Recognize the new classes that has to be developed (based on the previous analysis) in order to achieve the required functionality 3. Develop the code & tight the variables and relevant documentation (help docs etc) 4. Test the code for possible errors (internal test) and return to step 3 for any changes 5. Issue the final release Questions: 1. Are these steps correct? 2. Is it a necessity to develop new classes? Couldn't one use already developed classes or just subs and functions reside in some modules? 3. What percentage of total-time would each one of the development phases take? Best Regards
