Visual Numerics Inc. (formerly IMSL and Precision Visuals) is in the
process of securing sites for beta testing X Exponent Graphics 1.0 
and C Exponent Graphics 2.0.  (Both X Exponent Graphics and C Exponent
Graphics are 3GL products).  The beta period is from April 26 through 
June 18.  The platform is HP9000/700 running under OS 8.07 with 
ansi C 8.71 compiler.  The media will be sent on 4mm DAT cartridge 
tape.  Here are some of the key facts about the two products.
 
X Exponent Graphics 1.0 key facts:
 
1. Complete collection of high-level 2D and 3D application plot types
   available through a large collection of X resources.
2. Cstom widget for OSF/Motif developers.
3. Built-in interactive GUI for plot customization.
4. Easily-implemented callbacks for customized application feedback.
5. XEG 1.0, being built on the Xt Toolkit provides the user a widget 
   library that conforms to the expected syntax and standards familar 
   to X programmers.
6. XEG will also be sold as a bundle with Visual Edge's UIM/X product.
   This will enable user to use a GUI builder to create the graphical
   layout of an application.
 
C Exponent Graphics 2.0 key facts:
 
1. Written in C for C application programmers/developers.  The library
   is 100% written in C, and the programming interface conforms to C
   standards, taking advantage fo the most desirable features of C.
2. Build-in GUI for interactive plot customization.  Through mouse 
   interaction, the user has complete interactive graph output control
   with over 200 graphics attributes for plot customization.
3. Large collection of high-level application functions for "two-call"
   graph creation.  A wide variety of 2D and 3D plot types are available
   with minimal programming effort.
4. User ability to interrupt and control the X event.  By controlling
   the X event loop, when the user use the mouse to manipulate the  plot
   the user can allow CEG to control the event loop or the user can 
   control the event loop.
