+Problems with old systems that have known work-a-rounds:

+
+	  compiled optimized (-O, -O1, -O2 or -O3)
+
+	  	AND
+
+      	  compiled with debugging (-g or -g3)
+
+	  	AND
+
+	  when calc is compiled with readline (see USE_READLINE,
+	  READLINE_LIB and READLINE_INCLUDE in the Makefile)
+
+      This is known as the Redhat 7 readlne problem.
+
+      On Redhat, the gcc -v which has this problem is:
+
+	gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-85)
+
+      there may be other gcc versions that also suffer this fate.
+
+      The readlines associated with problem are:
+
+	readline-4.1-5
+	readline2.2.1-2.2.1-2
+	readline-devel-4.1-5
+
+      One work-a-round is to compile calc WITHOUT readline.  In the
+      Makefile be sure that:
+
+	USE_READLINE=
+	READLINE_LIB=
+	READLINE_INCLUDE=
+
+      i.e., these Makefile vars are empty.
+
+      If you must use readline, then an alternate work-a-round is to
+      change the DEBUG Makefile variable to either:
+
+	compile for speed:  -O3		(or -O2 if you do not have -O3)
+	compile to debug:   -g3		(or -g if you do not have -g3)

+Installing calc from the gziped tarball in 4 easy steps:
 
-    1) Look at the makefile, and adjust it to suit your needs.
+    0)  If your platform supports i686 RPMs, you may want to go to:
 
-       Here are some Makefile hints:
+	    http://www.isthe.com/chongo/src/calc/
 
-	   Select a compiler set by commenting in the appropriate set
-	   of cc options.  As shipped the Makefile assumes a gcc-like
-	   environment such as Linux.  If a more appropriate cc set if
-	   found below, comment out the Linux set and comment in that
-	   set or edit the gcc set or the common cc set as needed.
+	and use these RPMs:
 
-	   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.
+	    * calc*.i686.rpm
+		- all that is needed if you just want to use calc
 
-	   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.
+	    * calc-devel-*.i686.rpm
+	        - calc *.h header and *.a lib files for use in other programs
 
-	   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.
+	    * calc.*.src.rpm
+	        - calc source in RPM package form
 
-	   Set BINDIR to the place where calc is installed.  As shipped
-	   the Makefile assumes a BINDIR /usr/local/bin.
+	The following 4 steps apply to calc source tree that comes from either:
+
+		gunzip -c calc-*.tar.gz | tar -xvf -
+
+	or from:
+
+		rpm -ivh calc-*.src.rpm
+		cd /var/tmp
+		gunzip -c /usr/src/redhat/SOURCES/calc-*.tar.gz | tar -xvf -
+
+    1)	Look at the makefile, and adjust it to suit your needs.
+
+	The Makefile, as shipped, is suitable for installation under
+	Linux and Un*x-like environments.  For the most part, the default
+	values should work.  If in doubt, follow the 'When in doubt'
+	suggestion.
+
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+	! If you are building under Windoz or a Windoz-like environment !
+	! (such as Cygwin or DJGPP), read the README.WINDOWS file.      !
+	!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
+
+	You should determine if these Makefile variables are reasonable:
+
+	    INCDIR		Where the system include (.h) files are kept.
+	    BINDIR		Where to install calc binary files.
+	    LIBDIR		Where to install calc link library (*.a) files.
+	    CALC_SHAREDIR	Where to install calc help, .cal, startup, and
+	    			config files.
+
+	You may want to change the default installation locations for
+	these values, which are based on the 4 values listed above:
+
+	    HELPDIR            where the help directory is installed
+	    CALC_INCDIR        where the calc include files are installed
+	    CUSTOMCALDIR       where custom *.cal files are installed
+	    CUSTOMHELPDIR      where custom help files are installed
+	    CUSTOMINCPDIR      where custom .h files are installed
+	    SCRIPTDIR          where calc shell scripts are installed
+
+	If you want to install calc files under a top level directory,
+	then set the T value:
+
+	    The calc install is performed under $T, the calc build is
+	    performed under /.	The purpose for $T is to allow someone
+	    to install calc somewhere other than into the system area.
+
+	    For example, if:
+
+	    	BINDIR= /usr/bin
+		LIBDIR= /usr/lib
+		CALC_SHAREDIR= /usr/share/calc
+
+	    and if:
+
+	    	T= /var/tmp/testing
+
+	    Then the installation locations will be:
+
+		calc binary files:	/var/tmp/testing/usr/bin
+		calc link library:	/var/tmp/testing/usr/lib
+		calc help, .cal ...:	/var/tmp/testing/usr/share/calc
+		... etc ...		/var/tmp/testing/...
+
+	    If $T is empty, calc is installed under /, which is the same
+	    top of tree for which it was built.  If $T is non-empty, then
+	    calc is installed under $T, as if one had to chroot under
+	    $T for calc to operate.
+
+	Look for the section that starts:
+
+	    ################
+	    # compiler set #
+	    ################
+
+	    Select a compiler set by commenting in the appropriate set
+	    of cc options.  As shipped the Makefile assumes a gcc-like
+	    environment such as Linux.  If a more appropriate cc set if
+	    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 want to change these Makrfile variables from their defaults:
+
+	    RANLIB
+
+		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.
+
+	    CALCPAGER
+
+		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.
+
+	    DEBUG
+
+	       Some compilers (to put it mildly) have bugs.  Sometimes the
+	       DEBUG Makefile variable causes the compiler / optimizer to
+	       produce bad code.  Other compilers do just fine.
+
+	       If possible try to use DEBUG=-O3 -g3 (maximum optimization
+	       and debug symbols).  If the calc test fails (see step 3),
+	       try lowering either the -O value and/or the -g3.  Also try

+NAME
+    pmodm127 - calculate q mod 2^(2^127-1)
+
+SYNOPSIS
+    custom("pmodm127", q)
+
+TYPES
+    q		int > 0
+
+    return	int
+
+DESCRIPTION
+
+    This custom function will return the value:
+
+    	q mod 2^(2^127-1)
+
+    This custom function serves as a demonstration of how to write
+    a custom function.  It performs the equivalent of:
+
+	pmod(2, 2^127-1, q)
+
+    The return value is integer in the half open range: [0, q).
+
+    SPECIAL NOTE:
+
+	Can you find a value, q, for which this custom function returns 1?
+	If you do, send the value of q to chongo using the EMail address
+	found at:
+
+	    http://www.isthe.com/chongo/address.html
+

+SYNOPSIS

+
+TYPES
+    mode	real
+
+    return	real
+
+DESCRIPTION
+    By default, calc will output values according to the default base
+    as controlled by the base() builtin function.
+
+    The base2() builtin function, if given a non-zero argument, enables
+    double base output mode.  In double base output mode, calc values
+    are displayed twice, once according to base() and again according
+    to base2().  In double base output mode, the second time a value is
+    displayed, it is displayed within comments:
+
+	21701 /* 0x54c5 */
+
+    The arguments for base2() are identical to base() with the addition
+    of the 0 value:
+
+	     base2	equivalent
+		      config("mode2")'s
+
+	       2	"binary"	base 2 fractions

+	       8	"octal"		base 8 fractions
+			"oct"
+
+	      10	"real"		base 10 floating point
+			"float"
+			"default"
+
+	     -10	"integer"	base 10 integers

+			"hex"
+
+	     1/3	"fraction"	base 10 fractions

+
+	    1e20	"scientific"	base 10 scientific notation
+			"sci"
+			"exp"
+
+	       0	"off"		disable double base output
+
+    For convenience, any non-integer non-zero value is assumed to mean
+    base 10 fractions and any integer >= 2^64 is assumed to mean base 10
+    scientific notation.
+
+    These base2() calls have the same meaning as config("mode2", "fraction"):
+
+	base2(1/3)	base2(0.1415)	base2(16/37)
+
+    These base2() calls have the same meaning as config("mode2", "scientific"):
+
+	base2(1e20)	base2(2^64)	base2(2^8191-1)
+
+    However the base2() function will only return one of the base values

 DESCRIPTION
-    Returns the least non-negative integer n for which abs(x) < b^n.
+    Returns number of digits in the standard base-b representation
+    when x is truncated to an integer and the sign is ignored.
 
-    digits(x, b) = 0  if and only if abs(x) < 1.
+    To be more precise: when abs(int(x)) > 0, this function returns
+    the value 1 + ilog(x, b).  When abs(int(x)) == 0, then this
+    function returns the value 1.
 
-    For real x with absolute value >= 1, digits(x, b) is the number
-    of digits in the standard base-b "decimal" representation of int(abs(x));
-    this is also given by  1 + ilog(x, b).
+    If omitted, b is assumed to be 10.  If given, b must be an
+    integer > 1.
+
+    One should remember these special cases:
+
+	digits(12.3456) == 2    computes with the integer part only
+	digits(-1234) == 4      computes with the absolute value only
+	digits(0) == 1          specical case
+	digits(-0.123) == 1     combination of all of the above

+NAME
+    display - set and/or return decimal digits for displaying numbers
+
+SYNOPSIS
+    display([d])
+
+TYPES
+    d		integer >= 0
+
+    return	integer
+
+DESCRIPTION
+    When given an argument, this function sets the maximum number of
+    digits after the decimal point to be printed in real or exponential
+    mode in normal unformatted printing (print, strprint, fprint) or in
+    formatted printing (printf, strprintf, fprintf) when precision is
+    not specified.  The return value is the previous display digit value.
+
+    When given no arguments, this function returns the current
+    display digit value.
+
+    The builtin function:
+
+    	display(d)
+	display()
+
+    is an alias for:
+
+	config("display", d)
+	config("display")
+
+    The display digit value does not change the stored value of a number.
+    It only changes how a stored value is displayed.
+
+    Where rounding is necessary to display up to d decimal places,
+    the type of rounding to be used is controlled by config("outround").
+
+EXAMPLE
+    > print display(), 2/3
+    20 ~0.66666666666666666667
+
+    > print display(40), 2/3

-   If the variable A has a matrix value, then for integer indices
-   i_1, i_2, ..., equal in number to the number of ranges specified at
