Why Pascal is used without extensions?

Why Pascal is used without extensions?

- Pascal uses extensions to extend the features used in the language and to overall implementation of the code.

- The implementation is standardized to many processors and implementations when it is possible.

- Program that is coded with the language doesn’t use much extension due to the fact that it doesn’t require high performances.

- Extensions make the program more clean and portable to use by providing the interfaces to be used in programs.

- Library construction has become easy to use due the features of advanced interface and the portability that is being increased.
