Free Pascal is highly compatible with Delphi, which is based on the Pascal language. Free Pascal is a versatile language, suitable for a variety of tasks. It is used for developing applications and games, database systems, visual user interfaces, scientific and engineering applications, and for teaching programming. It is versatile in the sense that the same code can be compiled and run on multiple platforms, including Windows, Linux, Mac OS X, FreeBSD and more. Free Pascal is also extendable, allowing developers to create their own object-oriented language extensions. Free Pascal is highly reliable, thanks to its built-in error checking and exception handling. It also has a wide range of libraries that allow developers to quickly and easily create complex applications. It is a great choice for those looking for a powerful and versatile language.
