1967: |
An ALGOL-60 extension implemented on a Zuse Z 23 computer with
operators and a number of elementary functions for a new data type interval. |
1968/69: |
Implementation of the above language on a more powerful
computer, an Electrologica X8. |
1976: |
PASCAL-SC, a PASCAL extension implemented on a Z-80 microprocessor
with 64 KB main memory (funded by the german company Nixdorf).
The programming convenience of PASCAL-SC allowed a small group of collaborators
to implement a large number of problem solving routines with automatic
result verification within a few months. |
1980: |
PASCAL-SC with a large number of problem solving routines
was exhibited at the Hannover fair. |
1980/89: |
ACRITH-XSC, a FORTRAN 77 extension for the /370 architecture
was developed and implemented in cooperation with IBM. |
1983: |
IBM shipped the first edition of the ACRITH library. |
1986: |
ARITHMOS for BS 2000 (with Siemens) |
1990: |
IBM shipped ACRITH-XSC |
1990/91: |
Development of a new Runtime System (RTS) for PASCAL-XSC
in C |
1991: |
PASCAL-XSC shipped. The PASCAL-XSC system compiles a given
PASCAL-XSC source code into C code which is passed to a C-Compiler. |
1992: |
C++ class library C-XSC shipped, available for many computers
with C++ compiler translating der AT&T language standard 2.0 |
1993: |
"Numerical Toolbox for Verified Computing" in PASCAL-XSC is
published by Springer-Verlag. |
1994: |
"C++ Toolbox for Verified Computing" in C-XSC is published
by Springer-Verlag |
1996: |
Begin of the implementation of Fortran-XSC (TU Dresden, Prof. Walter) |
1997/98: |
Oberon-XSC (Universität Karlsruhe, Dr. P. Januschke;
ETH Zürich, Prof. Gutknecht) |
1997: |
XSC General Public License, all XSC software has been available
FREE OF CHARGE since 1997. |
