DAVIS, Calif., January 20, 2004 - SoftIntegration, Inc. today announced the availability of Ch 4.5 and Embedded Ch 4.5. Ch is a C/C++ interpreter for cross-platform scripting, 2D/3D plotting, numerical computing, shell programming and embedded scripting.

Ch 4.5 and Embedded Ch 4.5 continues SoftIntegration's leadership in scripting, numerical computing and embedded scripting. Major product enhancements include C++ features, file name completion using a tab key in command shell, easier interface with binary C/C++ libraries and embedded scripting, and bug fixes.

"SoftIntegration Ch provides an unmatched level of power and flexibility in C/C++ scripting, numerical computing and embedded scripting," said Dr. Dawn Cheng, president of SoftIntegration. "Ch is also a very effective interactive environment for teaching and learning programming in C and C++."

C/C++ interpreter

Ch supports 1999 ISO C Standard (C99) and C++ classes. Ch also supports many industry standards with over 8,000 functions including POSIX, socket/Winsock, X11/Motif, OpenGL, ODBC, C LAPACK, GTK+, Win32, and CGI. Functions in static or dynamical binary C/C++ libraries can be executed interpretively in scripting without re-compilation using Ch SDK.

Shell programming and cross-platform scripting

Ch shell is C compatible shell while C-shell (csh) is a C like shell. Ch is an interpretive implementation of C, similar to Unix/MS-DOS shells. Ch in Windows includes over 100 commonly-used Unix commands for portable shell programming. Ch can also be used as a login shell just like sh, csh and ksh. Ch bridges the gap between the C language and shell languages. With its built-in string type and many enhanced scripting features, Ch is an alternative to other scripting languages for automating repetitive tasks, regression test, and hardware testing with direct interface to hardware.

2D/3D plotting and numerical computing

Ch supports 2D/3D graphical plotting, C LAPACK, high level numeric functions.
Ch has built-in 2D/3D plotting support, generic mathematical functions and computational arrays for linear algebra and matrix computations, and advanced high-level numerical functions for linear systems, differential equation solving, integration, non-linear equations, Fourier analysis, curve fitting, etc. For example, linear system equation b = A*x can be written verbatim in Ch.

Ch numerical extensions are the best choice for numerical computing in C/C++ domain With SoftIntegration graphical library (SIGL), the same program using 2D/3D plotting features can be executed in Ch or compiled using C++ compilers without any modification.

Ch is ideal for rapid application development and deployment. For example, a Control System Toolkit for design and analysis of linear time-invariant control systems developed in Ch is available.

Interface with binary C/C++ libraries

Ch SDK 4.5 can easily integrate the existing C/C++ libraries as part of Ch scripting module. Functions and classes in static or dynamical libraries can be invoked in a Ch script file or Ch command shell.

Embeddable scripting

Ch 4.5 is optimized for embedded scripting. Embedded Ch allows users to embed Ch into other C/C++ application programs and hardware. It is ideal for open-architecture application integration. With Embedded Ch, C/C++ applications can be extended with all features of Ch. It allows execution of C/C++ scripts generated dynamically on-line. Embedded Ch has a small footprint. The pointer and time deterministic nature of the C language provides a perfect interface with hardware in real-time systems.

Ch toolkits and third party software support

Ch supports an increasing number of third party software applications. It includes Ch Control toolkit, Ch NAG Statistics Package, Ch CGI toolkit, Ch ODBC toolkit, Intel OpenCV for computer vision and image processing, National Instruments' data acquisition toolkit NI-DAQ and motion control toolkit NI-Motion, Barret Technology's Barret Hand robotic manipulator control, and Perl Compatible Regular Expressions, as well as IDE (Integrated Development Environment).

Pricing and Availability

Ch for Windows, Linux, Mac OS X, Solaris, and HP-UX is available. Ch Standard Edition is free for both commercial and non-commercial uses in all platforms. Ch Professional Edition is free for academic use and costs $399 for personal or commercial use.
