    By using the mathematical modules of PASCAL-XSC, numerical algorithms which deliver highly accurate and automatically verified results can be programmed easily. PASCAL-XSC simplifies the design of programs in engineering and scientific computation by modular program structure, user-defined operators, overloading of functions, procedures, and operators, functions and operators with arbitrary result type and dynamic arrays. Arithmetic standard modules for additional numerical data types including operators and standard functions of high accuracy and the exact evaluation of expressions provide the main numerical tools.
    Programs written in PASCAL-XSC are easily readable since all operations, even those in the higher mathematical spaces, have been realized as operators and can be used in conventional mathematical notation.
    In current compiler versions of PASCAL-XSC, the concept of dynamic arrays has been significantly extended. A user is now able to allocate a dynamic array variable several times and with different size during the execution of his or her program. Moreover, dynamic arrays may now be declared as components of other PASCAL structures such as records or static arrays.
