Known bugs:

None reported. We are sure some bugs exist. When you find them,
please let us know! See the above for details on how to report and
were to EMail your bug reports and hopefully patches to fix them.
* Many of the LIBRARY sections are incorrect now that libcalc.a
contains most of the calc system.

* There is some places in the source with obscure variable names
and not much in the way of comments. We need some major cleanup
and documentation.
Calc Mis-features:
* The following shell command (written in sh,ksh,bash-like form) works:
calc '/*
* comment
*/
print 2+3;'
However this (also written in sh,ksh,bash-like form) does not work:
echo '/*
* comment
*/
print 2+3;' | calc
The 2nd example will result in an 'Unterminated comment' error.
* Calc does not support the #! exec method. For example of the
following is placed in an executable file (assume the path to
calc is correct) called /tmp/xyzzy:
#!/usr/local/bin/calc
/*
* comment
*/
print 2+3;
Will result in '"tmp" is undefined' and '"xyzzy" is undefined'
error messages because calc considers $0 as an expression to
evaluate.

Following is the change from calc version 2.11.0t8 to date:
Moved 'wishlist' enhancements from the help/todo file to a new
help/wishlist file. Ordered, by priority, help/todo items into
Very High, High and Medium priority items.
The BUGS file now has a 'bugs' section as well as a 'mis-features'
section.
Improved how calc internally dealt with reading EOF or '\0' characters.
Calc now allows multiple defines to occur on the same line:
(Thanks goes to Ernest Bowen <ernie@turing.une.edu.au>)
define f8300(x) = x^2; define g8300(x) = 1 - x;
Improved calc's ability to deal with and recover from errors.
Added inputlevel() builtin to return the input processing level.
In an interact mode, inputlevel() returns 0. When directly reading
a calc script, inputlevel() returns 1. When reading a script which
in turn reads another script, inputlevel() returns 2. etc...
If $CALCRC has more than one file as in file1:file2 and an error
occurs in file1, then calc -c will not read file2.
Fixed some of the old EMail addresses found in calc documentation.
Following is the change from calc version 2.11.0t7 to 2.11.0t7.5:
Calc has some new command line flags / command line meaning:

calc-tester@postofc.corp.sgi.com
* In general use faster algorithms for large numbers when they
become known. In particular, look at better algorithms for
very large numbers -- multiply, square and mod in particular.
See also the 'wishlist' help files for the calc enhancement wish list.
* Implement an autoload feature. Associate a calc library filename
with a function or global variable. On the first reference of
such item, perform an automatic load of that file.
=-=
* Add error handling statements, so that QUITs, errors from the
'eval' function, division by zeroes, and so on can be caught.
This should be done using syntax similar to:
Very High priority items:
ONERROR statement DO statement;
* Write the help file for the inputlevel() builtin function.
Something like signal isn't versatile enough.
* Write the help file for the display() builtin function.
* Add a debugging capability so that functions can be single stepped,
breakpoints inserted, variables displayed, and so on.
* Write the help file for the stoponerror() builtin function.
* Figure out how to write all variables out to a file, including
deeply nested arrays, lists, and objects.
* Update the errmax about the meaning of errmax(-1).
Add the ability to read and write a value in some binary form.
Clearly this is easy for non-neg integers. The question of
everything else is worth pondering.
* Document the new meanings for bit values and the sign of
of config("lib_debug") in the appropriate help file(s).
* Eliminate the need for the define keyword by doing smarter parsing.
* Fix any 'Known bugs' as noted in the BUGS file or as
displayed by 'calc help bugs'.
* Allow results of a command (or all commands) to be re-directed to a
file or piped into a command.
=-=
* Add some kind of #include and #define facility. Perhaps use
the C pre-processor itself?
High priority items:
* Support a more general input and output base mode other than
just dec, hex or octal.
* Verify, complete or fix the 'SEE ALSO' help file sections.
* Implement a form of symbolic algebra. Work on this has already
begun. This will use backquotes to define expressions, and new
functions will be able to act on expressions. For example:
* Verify, complete or fix the 'LIBRARY' help file sections.
x = `hello * strlen(mom)`;
x = sub(x, `hello`, `hello + 1`);
x = sub(x, `hello`, 10, `mom`, "curds");
eval(x);
* Verify, complete or fix the 'LIMITS' help file sections.
prints 55.
* Verify, complete or fix the 'SYNOPSIS' and 'TYPES' help file sections.
* Place the results of previous commands into a parallel history list.
Add a binding that returns the saved result of the command so
that one does not need to re-execute a previous command simply
to obtain its value.
* Where reasonable, be sure that regress.cal tests builtin functions.
If you have a command that takes a very long time to execute,
it would be nice if you could get at its result without having
to spend the time to reexecute it.
* Perform a code coverage analysis of the 'make check' action
and improve the coverage (within reason) of the regress.cal suite.
* Add a binding to delete a value from the history list.
* Create a Linux rpm (Red Hat Package Manager) package for calc.
One may need to remove a large value from the history list if
it is very large. Deleting the value would replace the history
entry with a null value.
* Address, if possible and reasonable, any Calc Mis-features
as noted in the BUGS file or as displayed by 'calc help bugs'.
* Add a binding to delete a command from the history list.
* The shell script that is currently constructed to display a help
file (in help.c) is a gross hack. That code should be replaced
with code that looks for the help file in the pre-defined help

then a $PAGER should be forked and execed after doing things such
as closing open file descriptors that the $PAGER does not need.
Since you can delete values, you might as well be able to
delete commands.

initial x.y.z version ... prior to any t sub-version) to help
ensure that they have not introduced new or re-introduced old bugs
into calc.

=-=
In some cases, 256 values is too small, in others it is too large.
Medium priority items:
* Add a builtin that returns a value from the history list.
As an example:
histval(-10)
returns the 10th value on the history value list, if such
a value is in the history list (null otherwise). And:
histval(23)
return the value of the 23rd command given to calc, if
such a value is in the history list (null otherwise).
It would be very helpful to use the history values in
subsequent equations.
* Add a builtin that returns command as a string from the
history list. As an example:
history(-10)
returns a string containing the 10th command on the
history list, if a such a value is in the history list
(empty string otherwise). And:
history(23)
return the string containing the 23rd command given to calc, if
such a value is in the history list (empty string otherwise).
One could use the eval() function to re-evaluate the command.
* Allow one to optionally restore the command number to calc
prompts. When going back in the history list, indicate the
command number that is being examined.
The command number was a useful item. When one is scanning the
history list, knowing where you are is hard without it. It can
get confusing when the history list wraps or when you use
search bindings. Command numbers would be useful in
conjunction with positive args for the history() and histval()
functions as suggested above.
* Add a builtin that returns the current command number.
For example:
cmdnum()
returns the current command number.
This would allow one to tag a value in the history list. One
could save the result of cmdnum() in a variable and later use
it as an arg to the histval() or history() functions.
* Add a factoring builtin functions. Provide functions that perform
multiple polynomial quadratic sieves, elliptic curve, difference
of two squares, N-1 factoring as so on. Provide a easy general
factoring builtin (say factor(foo)) that would attempt to apply
whatever process was needed based on the value.
Factoring builtins would return a matrix of factors.
It would be handy to configure, via config(), the maximum time
that one should try to factor a number. By default the time
should be infinite. If one set the time limit to a finite
value and the time limit was exceeded, the factoring builtin
would return whatever if had found thus far, even if no new
factors had been found.
Another factoring configuration interface, via config(), that
is needed would be to direct the factoring builtins to return
as soon as a factor was found.
* Allow one to config calc break up long output lines.
The command: calc '2^100000' will produce one very long
line. Many times this is reasonable. Long output lines
are a problem for some utilities. It would be nice if one
could configure, via config(), calc to fold long lines.
By default, calc should continue to produce long lines.
One option to config should be to specify the length to
fold output. Another option should be to append a trailing
\ on folded lines (as some symbolic packages use).
* Allow one to use the READ and WRITE commands inside a function.
* Remove or increase limits on factor(), lfactor(), isprime(),
nextprime(), and prevprime(). Currently these functions cannot
search for factors > 2^32.
* Add read -once -try "filename" which would do nothing
if "filename" was not a readable file.
* Complete the use of CONST where appropirate:

Calc Enhancement Wish List:
Send calc comments, suggestions, bug fixes, enhancements and
interesting calc scripts that you would like you see included in
future distributions to:
calc-tester@postofc.corp.sgi.com
The following items are in the calc wish list. Programs like this
can be extended and improved forever.
See the 'todo' help file for higher priority todo items.
=-=
* In general use faster algorithms for large numbers when they
become known. In particular, look at better algorithms for
very large numbers -- multiply, square and mod in particular.
* Implement an autoload feature. Associate a calc library filename
with a function or global variable. On the first reference of
such item, perform an automatic load of that file.
* Add error handling statements, so that QUITs, errors from the
'eval' function, division by zeroes, and so on can be caught.
This should be done using syntax similar to:
ONERROR statement DO statement;
Something like signal isn't versatile enough.
* Add a debugging capability so that functions can be single stepped,
breakpoints inserted, variables displayed, and so on.
* Figure out how to write all variables out to a file, including
deeply nested arrays, lists, and objects.
Add the ability to read and write a value in some binary form.
Clearly this is easy for non-neg integers. The question of
everything else is worth pondering.
* Eliminate the need for the define keyword by doing smarter parsing.
* Allow results of a command (or all commands) to be re-directed to a
file or piped into a command.
* Add some kind of #include and #define facility. Perhaps use
the C pre-processor itself?
* Support a more general input and output base mode other than
just dec, hex or octal.
* Implement a form of symbolic algebra. Work on this has already
begun. This will use backquotes to define expressions, and new
functions will be able to act on expressions. For example:
x = `hello * strlen(mom)`;
x = sub(x, `hello`, `hello + 1`);
x = sub(x, `hello`, 10, `mom`, "curds");
eval(x);
prints 55.
* Place the results of previous commands into a parallel history list.
Add a binding that returns the saved result of the command so
that one does not need to re-execute a previous command simply
to obtain its value.
If you have a command that takes a very long time to execute,
it would be nice if you could get at its result without having
to spend the time to reexecute it.
* Add a binding to delete a value from the history list.
One may need to remove a large value from the history list if
it is very large. Deleting the value would replace the history
entry with a null value.
* Add a binding to delete a command from the history list.
Since you can delete values, you might as well be able to
delete commands.
* All one to alter the size of the history list thru config().
