      New HCR/C++ Provides Full Set of Libraries for Users,
      Extends Company Lead in Advanced Compiler Technology

     TORONTO, Ontario, Jan. 17 -- HCR Corporation, which last
year provided UNIX programmers with the first packaged C++
compiler, based on AT&T's Release 2.0, today announced a major
upgrade, HCR/C++ Version 2.2.  HCR/C++ operates on most popular
386 and 486 UNIX systems.

     Along with significant performance enhancements, Version 2.2
provides users with class libraries containing a comprehensive
set of pre-defined objects that permit them to take full
advantage of the reusable object capabilities of C++.  In
addition, HCR/C++ 2.2 also includes a significantly enhanced
release of a powerful window-oriented debugger, upward compatible
with Berkeley's dbx.

     HCR/C++ has always included the full set of class libraries
defined by AT&T (task, complex and I/O).  With Version 2.2 of
HCR/C++, HCR has added a set of significant extensions.  The
popular NIH (National Institute of Health) class libraries are
included in source format.  These libraries include classes for
strings, linked lists, date and time conversions, indexed arrays,
hash tables, regular expressions and vector operations.  In
short, they make almost any C++ program easier to write.  Also
included are the InterViews libraries; these provide a simplified
interface to X Windows.  As such, they are a major productivity
enhancement for an X Window developer.

     "Our initial C++ compiler was received enthusiastically by
users worldwide," said Brian Eisenberg, vice president of sales
and marketing.  "Many of them suggested that we provide class
libraries in our upgrade, and Version 2.2 provides a rich set of
them, with the objects they need to fully exploit the compiler's
power."

     Overall performance improvements have made Version 2.2 even
more robust and error-free than Version 2.1.  Important
enhancements have been completed to dbXtra; for example, hardware
debug registers speed up execution by up to 300 times when
tracing access to variables.  HCR/C++ 2.2 also displays C and C++
source code, program output, display expressions and debug output
at the same time through windows on both graphics and ASCII
terminals.

     Eisenberg emphasized that Version 2.2, like its predecessor,
is fully compatible with AT&T's cfront 2.0.  "Our commitment to
complete compatibility is unswerving," he said.

     HCR/C++ Version 2.2 is available Feb. 15 for a base price of
U.S.$995.  Version 2.1 customers can obtain 2.2 for $99.  New
users who order before March 15 will receive from HCR a set of
publications about C++ and its uses, each valued at around $30.
The publications include "C++ for C Programmers", by Ira Pohl;
"The C++ Answer Book", by Tony Hansen; "A C++ Workbook", by
Richard Weiner and Lewis Pinson; and "Programming in C++", by
Kathy Stark and Stephen Dewherst.

     C++ is a comprehensive extension of the C programming
language that preserves compatibility with C while supporting
modern, object oriented programming methodology.  HCR/C++ 2.2
provides all of the key features of AT&T Release 2.0, such as
type safe linkages, default membership initialization, and the
ability of each class to define its own "new" and "delete"
operators.

     HCR's dbXtra adds the ability to operate through windows,
permitting users to review their output and source code easily,
even on standard terminals.  In HCR/C++, dbXtra is linked to C++,
allowing source-level debugging of C++ as well as access to the
translated C source code.  dbXtra can also be used to debug C
programs produced by standard (COFF) UNIX compilers.  HCR's
standard full service support and upgrade options are available.

     Founded in 1976, HCR Corporation develops system software
for the expanding UNIX market.  HCR's products include both
custom and packaged software in the areas of UNIX operating
systems, development tools and networking.  The company has
provided products and services to clients such as IBM, Control
