IBM's Program Product ACRITH-XSC

[Wolfgang Walter]

Dear Fortran experts,

This note is to inform you that the new IBM program product
High Accuracy Arithmetic - Extended Scientific Computation,
ACRITH-XSC for short, is now available for IBM /370 systems
running under VM/SP or VM/XA.

ACRITH-XSC is a Fortran-like programming language designed
for numerical applications programming.
It was originally developed under the name of FORTRAN-SC.
ACRITH-XSC offers a large number of predefined operators and functions
with a precisely defined mathematical behavior. The result of every
arithmetic operator - including vector/matrix-products (dot products) -
is accurate to 1 ulp (unit in the last place). The user has a choice
of roundings similar to that of the IEEE arithmetic standard 754.
ACRITH-XSC is particularly useful for Fortran programmers who have
been using IBM's High Accuracy Arithmetic Subroutine Library, ACRITH.
By providing simple interfaces for virtually all ACRITH routines,
ACRITH-XSC allows a natural, math-like notation.
Other features of ACRITH-XSC include dynamic arrays, subarrays,
user-defined operators, exact dot products, dot product expressions,
and real and complex interval arithmetic.

If you have any questions about ACRITH-XSC, feel free to contact me:
