CC is a programmable graphing mathematics processor for your PC.  The present
program is a beta test copy of version 4 of CC.  Changes from the published
version 3 can be found in the file UPDATE.CC on this disk.  I expect that
this version will be published in January 1993.

Please report bugs and suggestions for improvements to

Version 3 of CC has been published by the College Division of Prentice Hall
with a 200 page manual.  It can be obtained through any bookstore--the ISBN
number is 0-13-117441-X--or by calling 201-767-5937.  The cost is around
$30.00

LAST MINUTE FLASH:  CC has had a name change just before publication.  Now
this late beta version carries the new name:  X(PLORE)-The Mathematical
Toolchest.  Files are called XPL instead of CC.  Publication still
scheduled for 1/93.
