Seed7 is a general purpose programming language. It is a higher level language, which means that it is easier to learn and use than a lower level language such as C or Assembly.
Seed7 was created in order to increase the level of abstraction of the programming language C. The creator, Thomas Mertes, felt that C was too low level and that it was missing a lot of features that would make it more user friendly.
Seed7 has a lot of features that make it unique. It has a strong type system, which means that it can catch more errors than other languages. It also has a powerful module system, which allows you to reuse code more easily.
Overall, Seed7 is a very powerful and unique programming language. It is perfect for those who want to increase their level of abstraction, or for those who want to use a language with more features than C.
