\section{The [[BOOT]] package}

Everything in axiom that the user references eventually shows
up here. The interpreter and the algebra are run after switching
to the boot package (in-package "BOOT") so any symbol that the
interpreter or algebra uses has to (cough, cough) appear here.

<<license>>

;; This is a horrible hack to work around a horrible bug in GCL
;; as reported here:
;;    http://lists.gnu.org/archive/html/gcl-devel/2007-08/msg00004.html
#+:gcl (in-package "VMLISP")
#+:gcl (in-package "AxiomCore")

(IMPORT-MODULE "hash")
(defpackage "BOOT"
  #+:common-lisp (:use "COMMON-LISP")
  #-:common-lisp (:use "LISP")
  (:use "VMLISP" "AxiomCore"))

@

Note that it is confusing the package \Tool{Axiom}'s compiler and
interpreter use is called [[BOOT]].  It should have been
[[Spad]], or better yet [[Axiom]].


\section{Constants}

\subsection{\$EmptyMode}

[[$EmptyMode]] is a contant whose value is [[$EmptyMode]].
It is used by [[isPartialMode]] (in [[i-funsel.boot]]) to
decide if a modemap is partially constructed. If the [[$EmptyMode]]
constant occurs anywhere in the modemap structure at any depth
then the modemap is still incomplete. To find this constant the
[[isPartialMode]] function calls [[CONTAINED |$EmptyMode| Y]]
which will walk the structure $Y$ looking for this constant.
<<EmptyMode>>=
(def-boot-val |$EmptyMode| '|$EmptyMode|    "compiler constant")

\section{Portability issues}

This section discusses some portability issues known to affect
this module.

\subsection{[[compiler-let]]}

The construct [[compiler-let]] is not part of ANSI Lisp, although
it had been described in CLTL.  Therefore some Lisp implementations
offer it as extensions.

<<non-portable-codes>>=
#+:clisp (import 'ext:compiler-let)
@

\subsection{Missing DFLOAT Transcendental functions}

These functions should be defined for DoubleFloat inputs but are not.
These are cheap and easy definitions that work but should be rewritten.
<<Missing DFLOAT Transcendental functions>>=
(defun sec (x) (/ 1 (cos x)))
(defun csc (x) (/ 1 (sin x)))
(defun acsc (x) (asin (/ 1 x)))
(defun asec (x) (acos (/ 1 x)))
(defun csch (x) (/ 1 (sinh x)))
(defun coth (x) (* (cosh x) (csch x)))
(defun sech (x) (/ 1 (cosh x)))
(defun acsch (x) (asinh (/ 1 x)))
(defun acoth (x) (atanh (/ 1 x)))
(defun asech (x) (acosh (/ 1 x)))
@

\subsection{The manexp fix}

Contributed by Juergen Weiss from a suggestion by Arthur Norman.
This is a Mantissa and Exponent function. 
<<manexp>>=
#+(or :cmu :akcl :gcl)
(defun manexp (u)
  (multiple-value-bind (f e s) 
    (decode-float u)
    (cons (* s f) e)))

@

\subsection{The arc cotangent function}

Contributed by Juergen Weiss from Arthur Norman's CCL.
<<acot>>=
#+(or :cmu :akcl :gcl)
(defun acot (a)
  (if (> a 0.0)
    (if (> a 1.0)
       (atan (/ 1.0 a))
       (- (/ pi 2.0) (atan a)))
    (if (< a -1.0)
       (- pi (atan (/ -1.0 a)))
       (+ (/ pi 2.0) (atan (- a))))))

@

\subsection{The arc cotangent function}

Contributed by Juergen Weiss from Arthur Norman's CCL.
<<cot>>=
#+(or :cmu :akcl :gcl)
(defun cot (a)
  (if (or (> a 1000.0) (< a -1000.0))
    (/ (cos a) (sin a))
    (/ 1.0 (tan a))))

@

\subsection{The get-current-directory function}

Contributed by Juergen Weiss.
<<getCD>>=
#+:cmu
(defun get-current-directory ()
  (namestring (extensions::default-directory)))

#+(or :akcl :gcl)
(defun get-current-directory ()
