Pascal Programming Language funktioniert nicht

Pascal is an influential imperative and procedural programming language, designed in 1968/9 and published in 1970 by Niklaus Wirth as a small and efficient language intended to encourage good programming practices using structured programming and data structuring.  Internet connection is required. - Enhanced source code editor with syntax highlighting, line numbers, color themes and additional keyboard. - Import and export programs by iTunes or by email. - Online language reference and several program samples. - Internet connection is required to compile and run a program. - Graphics, network, file system and real-time input are not supported. - Maximum running time of a program is 15 seconds.  Pascal was developed by Niklaus Wirth and based on the ALGOL programming language, named in honor of the French mathematician and philosopher Blaise Pascal.  Knuth was written in WEB, the original literate programming system, based on DEC PDP-10 Pascal, while an application like Total Commander was written in Delphi (Object Pascal).  The application is especially useful for learning the Pascal programming language.  The classic Pascal programming language for iPad, iPhone and iPod touch.  Parts of the original Macintosh operating system were hand-translated into Motorola 68000 assembly language from the Pascal sources.  A derivative known as Object Pascal designed for object-oriented programming was developed in 1985.  Pascal was the primary high-level language used for development in the Apple Lisa, and in the early years of the Mac.  Initially, Pascal was largely, but not exclusively, intended to teach students structured programming.  Prior to his work on Pascal, Wirth had developed Euler and ALGOL W and later went on to develop the Pascal-like languages Modula-2 and Oberon.  A generation of students used Pascal as an introductory language in undergraduate courses.  Programming language is a perfect tool for studying, complex mathematical calculation, entertainment and many other useful tasks.  Variants of Pascal have also frequently been used for everything from research projects to PC games and embedded systems.  Object Pascal is still used for developing Windows applications.  Newer Pascal compilers exist which are widely used.
