+	    main(){SVAL(b8a8aeb0,8168eadc);}
+
+      fails because it puts a space inside the concatenated hex.  Calc
+      has code that is affected by this bug.  This bug has been reported
+      to Compaq and may be fixed in the future.	 A work-a-round is to
+      compile with cc -std0 or to use a later version of their compiler.
+
+    * On a Digital UNIX V4.0F (Rev. 1229) on a 500 Mhz 21264, make check
+      dies a horrible death starting in test 600 and 622 gives 100s of
+      messages for calc version 2.11.0t9.4 using the Dec's cc with -O2:
+
+	600: Beginning test_bignums
+	601: muldivcheck 1
+	**** abc != acb: 602: muldivcheck 2

+	**** t4 != a4: 622: algcheck 1
+	...
+
+	it finally hangs at test 2000.
+
+      The work-a-round is to compile calc without the optimizer.  If this
+      happens to you, try compiling without -O and without -O2.	 I.e., in
+      the Makefile, set:
+
+	DEBUG= -g
+
+    * There are problems compiling calc on the sparcv9 under 64 bit
+      Solaris.	On that platform, gcc-2.96 is able to compile calc, but
+      calc dumps core very early on in startup.	 It is said that sparcv9
+      support in gcc-2.96 is very unofficial and thus there is no
+      work-a-round for gcc-2-96.
+
+      There is a work-a-round for this architecture us one is using the
+      Solaris CC on the sparcv9.  It has been reported that setting the
+      following Makefile variables will produce a working version of
+      calc on the sparcv9 under 64 bit Solaris:
+
+	    LCC="cc -xarch=v9"
+	    CCWARN="-DFORCE_STDC -w"
+	    DEBUG="-fast -xarch=v9"
+
+    * Under BSDI v4, the warnings of the form:
+
+	/usr/include/ctype.h:147: warning: `__runetype' defined but not used
+	/usr/include/ctype.h:161: warning: `__isctype' defined but not used
+	/usr/include/ctype.h:170: warning: `toupper' defined but not used
+	/usr/include/ctype.h:177: warning: `tolower' defined but not used
+
+      are seen.	 These warnings are the result of mis-features in BSDI
+      include files.  They do not have an impact on the operation
+      or performance.  The work-a-round is to ignore these warnings
+      under BSDI.

+Calc's relationship to the GNU Lesser General Public License
+------------------------------------------------------------
+
+    In section 0 of the GNU Lesser General Public License, one finds
+    the following definition:
+
+	The "Library", below, refers to any such software library or
+	work which has been distributed under these terms.
+
+    Calc is distributed under the terms of the GNU Lesser
+    General Public License.
+
+    In the same section 0, one also find the following:
+
+	For a library, complete source code means all the source code
+	for all modules it contains, plus any associated interface
+	definition files, plus the scripts used to control compilation
+	and installation of the library.
+
+    There are at least two calc binary link libraries found in calc:
+
+	libcalc.a	libcustcalc.a
+
+    Clearly all files that go into the creation of those binary link
+    libraries are covered under the License.
+
+    The ``scripts used to control compilation and installation of the
+    of the library'' include:
+
+	* Makefiles
+	* source files created by the Makefiles
+	* source code used in the creation of intermediate source files
+
+     All of those files are covered under the License.
+
+     The ``associated interface definition files'' are those files that:
+
+	* show how the calc binary link libraries are used
+	* test the validity of the binary link libraries
+	* document routines found in the binary link libraries
+	* show how one can interactively use the binary link libraries
+
+     Calc provides an extensive set of files that perform the above
+     functions.
+
+	* files under the sample sub-directory
+	* files under the help sub-directory
+	* files under the lib sub-directory
+	* the main calc.c file
+
+     The ``complete source code'' includes ALL files shipped with calc,
+     except for the exception files explicitly listed in the ``Calc
+     copyrights and exception files'' section below.

+    As you can read in the above URL, there are times where a library
+    cannot give free software any particular advantage.	 One of those
+    times is when there is significantly similar versions available
+    that are not covered under a Copyleft such as the GNU General Public
+    License.
+
+    The reason why calc was placed under the GNU Lesser General Public
+    License is because for many years (1984 thru 1999), calc was offered
+    without any form of Copyleft.  At the time calc was placed under
+    the GNU Lesser General Public License, a number of systems and
+    distributions distributed calc without a Copyleft.

+

+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+			    NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+
+       Here are some Makefile hints:
+
+	   Select a compiler set by commenting in the appropriate set
+	   of cc options.  As shipped the Makefile assumes a gcc-like

+	   found below, comment out the Linux set and comment in that
+	   set or edit the gcc set or the common cc set as needed.
+
+	   You may or may not need RANLIB when building libraries.
+	   As shipped the Makefile assumes RANLIB is needed.
+	   Comment the in/out the RANLIB value if ranlib does
+	   not work or does not exist.
+
+	   You may want to change the default pager used by calc.
+	   As shipped the Makefile assumes 'more'.  On your system
+	   you may find 'less' to be a better pager.
+
+	   Set TOPDIR to be the place under which help files, calc,
+	   include files and calc libs are to be installed.  As shipped
+	   the Makefile assumes a TOPDIR of /usr/local/lib.
+
+	   Set BINDIR to the place where calc is installed.  As shipped

-Dear alpha tester,
-
-Thanks for taking the time to try out this alpha version of calc!  We are
-interested in any/all feedback that you may have on this version.  In
-particular we would like to hear about:
-
-    * compile problems
-    * regression test problems (try: make check)
-    * compiler warnings
-    * special compile flags/options that you needed
-    * Makefile problems
-    * help file problems
-    * misc nits and typos
-
-We would like to offer a clean compile across a wide verity of platforms,
-so if you can test on several, so much the better!
-
-Calc distributions may be obtained from:
-
-	ftp://ftp.uu.net/pub/calc
-
-If you don't have ftp access to that site, or if you do not find a more
-recent version (you may have a special pre-released version that is
-more advanced than what is in the ftp archive) send EMail to:
-
-	chongo@toad.com
-
-Indicate the version you have and that you would like a more up
-to date version.
-
-=-=
-
-Misc items TODO before Beta release:
-
-    * improve the coverage in the 'SEE ALSO' help file lists
-
-    * where reasonable, be sure that regress.cal tests builtin functions
-
-    * add the Blum-Blum-Shub random() generator code
-
-    * add code to allow of the reading, writing and processing of binary data
-
-    * add shs, shs-1 and md5 hashing functions.  Use align32.h.
-
-    * add mod h*2^n+/-1 function for integers
-
-    * be sure that CHANGES is up to date,
-      look over the help/todo file and update as needed,
-      revisit issues in the BUGS file and
-      change this file  :-)
-
-    * clean the source code and document it better

+Calc standard resource files
+----------------------------
 
-The following calc library files are provided because they serve as
-examples of how use the calc language, and/or because the authors thought
-them to be useful!
+To load a reosurce file, try:
+
+    read filename
+
+You do not need to add the .cal extension to the filename.  Calc
+will search along the $CALCPATH (see ``help environment'').
+
+Normally a resource file will simply define some functions.  By default,
+most resource files will print out a short message when they are read.
+For example:
+
+    > read lucas
+    lucas(h,n) defined
+    gen_u0(h,n,v1) defined
+    gen_v1(h,n) defined
+    ldebug(funct,str) defined
+
+will cause calc to load and execute the 'lucas.cal' resource file.
+Executing the resource file will cause several functions to be defined.
+Executing the lucas function:
+
+    > lucas(149,60)
+	    1
+    > lucas(146,61)
+	    0
+
+shows that 149*2^60-1 is prime whereas 146*2^61-1 is not.

+This will cause the needed resource files to be read once.  If these

-By convention, the config parameter "lib_debug"  is used to control
-the verbosity of debug information printed by lib files.  By default,
-the "lib_debug" has a value of 0.
+The "resource_debug" parameter is intended for controlling the possible
+display of special information relating to functions, objects, and
+other structures created by instructions in calc resoure files.
+Zero value of config("resource_debug") means that no such information
+is displayed.  For other values, the non-zero bits which currently
+have meanings are as follows:
 
-The "lib_debug" config parameter takes the place of the lib_debug
-global variable.  By convention, "lib_debug" has the following meanings:
+    n	    Meaning of bit n of config("resource_debug")
 
-	<-1	no debug messages are printed though some internal
-		    debug actions and information may be collected
+    0	When a function is defined, redefined or undefined at
+	interactive level, a message saying what has been done
+	is displayed.
 
-	-1	no debug messages are printed, no debug actions will be taken
+    1	When a function is defined, redefined or undefined during
+	the reading of a file, a message saying what has been done
+	is displayed.
 
-	0	only usage message regarding each important object are
-		    printed at the time of the read (default)
+The value for config("resource_debug") in both oldstd and newstd is 3,
+but if calc is invoked with the -d flag, its initial value is zero.
+Thus, if calc is started without the -d flag, until config("resource_debug")
+is changed, a message will be output when a function is defined
+either interactively or during the reading of a file.
 
-	>0	messages regarding each important object are
-		    printed at the time of the read in addition
-		    to other debug messages
+Sometimes the information printed is not enough.  In addition to the
+standard information, one might want to print:
 
-To conform to the above convention, your lib files should end with
-lines of the form:
+	* useful obj definitions
+	* functions with optional args
+	* functions with optional args where the param() interface is used
 
-	if (config("lib_debug") >= 0) {
+For these cases we suggest that you place at the bottom of your code
+something that prints extra information if config("resource_debug") has
+either of the bottom 2 bits set:
+
+	if (config("resource_debug") & 3) {
 		print "obj xyz defined";
-		print "funcA(side_a, side_b, side_c) defined";
-		print "funcB(size, mass) defined";
+		print "funcA([val1 [, val2]]) defined";
