If you notice something wrong, strange or broken, try rereading:

   README.FIRST
   HOWTO.INSTALL
   BUGS (this file)

If that does not help, cd to the calc source directory and try:

   make check

Look at the end of the output, it should say something like:

    9998: passed all tests  /\../\
    9999: Ending regression tests

If it does not, then something is really broken!

If you made and modifications to calc beyond the simple Makefile
configuration, try backing them out and see if things get better.

To be sure that your version of calc is up to date, check out:

If you have tried all of the above and things still are not right,
then it may be time to send in a bug report.  You can send bug
and bug fixes reports to:

	calc-bug-report at asthe dot com

	NOTE: Remove spaces and replace 'at' with @, 'dot' with .

    This replaces the old calc-bugs at asthe dot com address.

    To be sure we see your EMail reporting a calc bug, please use the
    following phase in your EMail Subject line:

	calc bug report

    That phrase in your subject line will help ensure your request
    will get past our anti-spam filters.  You may have additional
    words in your subject line.

    However, you may find it more helpful to simply subscribe
    to the calc-tester mailing list (see below) and then to
    send your report to that mailing list as a wider set calc
    testers may be able to help you.

When you send your report, please include the following information:

    * a description of the problem
    * the version of calc you are using (if you cannot get calc
      to run, then send us the 4 #define lines from version.c)
    * if you modified calc from an official patch, send me the mods you made
    * the type of system you were using
    * the type of compiler you were using
    * any compiler warnings or errors that you saw
    * cd to the calc source directory, and type:

	make debug > debug.out 2>&1		(sh, ksh, bash users)
	make debug >& debug.out			(csh, tcsh users)

      and send the contents of the 'debug.out' file.

Stack traces from core dumps are useful to send as well.

Fell free to use the above address to send in big fixes (in the form
of a context diff patch).

Known bugs:

    The output of the alg_config.cal resource file is bogus.
    We would welcome a replacement for this code.

    We are sure some more 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.

mis-features in calc:

    Some problems are not bugs but rather mis-features / things that could
    work better.  The following is a list of mis-features that should be
    addressed and improved someday.

    * When statement is of the form { ... }, the leading { MUST BE ON
      THE SAME LINE as the if, for, while or do keyword.

      This works as expected:

	if (expr) {
	    ...
	}

      However this WILL NOT WORK AS EXPECTED:

	if (expr)
	{
	    ...
	}

      This needs to be changed.  See also "help statement", "help unexpected",
      and "help todo".

    * The chi.cal resource file does not work well with odd degrees
      of freedom.  Can someone improve this algorithm?

    * The intfile.cal resource file reads and writes big or little Endian
      integers to/from files the hard way.  It does NOT use blkcpy.  The
      following code:

	i = (ord("\n") << 16) | (ord("i") << 8) | ord("H")
	b = blk()
	copy(i, b)
	fd = fopen("file", "w")
	copy(b, fd);
	fclose(fd)

      will write an extra NUL octet to the file.  Where as:

	read intfile
	i = (ord("\n") << 16) | (ord("i") << 8) | ord("H")
	be2file(i, "file2")

      will not.
