Thank you very much for the advice. I have just installed the software and I'll start to use it and learn thereby ADA programming which I have postponed due to laziness up till now. I am very happy to know also that it has support for C so that some of my C codes would be reusable. Besides it happens to be my luck that the software is a major new version released only a few months ago. Out of curiosity I have a tiny question: Does the software somehow finds out during installation whether the architecture on which it is installed is 32-bit or 64-bit and correspondingly chooses the most efficient way for machine code generation?
