Conclusion
Software design and portability

Software portability is not a matter of formalized technique. Common sense and the search for information guide the developer in making the right choices. Knowing which level of integration into the operating system is possible, or which external tools to use, is the result of serious study to avoid setbacks. The choice of languages is a key element. Our preference is for the abstract machine when the software being developed is destined to live for a long time. But this technique requires considerable skills and resources. Otherwise, a standardized language is a good choice. You should also try to respect your own programming techniques and carefully organize your code. Experience shows that impasses in this area always prove costly when software is ported. Finally, it may be worthwhile to look for code generation tools on the market that guarantee the portability of application modules...
