-
-On October 1, 2001 Axiom was withdrawn from the market and ended
-life as a commercial product.
-On September 3, 2002 Axiom was released under the Modified BSD
-license, including this document.
-On August 27, 2003 Axiom was released as free and open source
-software available for download from the Free Software Foundation's
-website, Savannah.
-
-Work on Axiom has had the generous support of the Center for
-Algorithms and Interactive Scientific Computation (CAISS) at
-City College of New York. Special thanks go to Dr. Gilbert
-Baumslag for his support of the long term goal.
-
-The online version of this documentation is roughly 1000 pages.
-In order to make printed versions we've broken it up into three
-volumes. The first volume is tutorial in nature. The second volume
-is for programmers. The third volume is reference material. We've
-also added a fourth volume for developers. All of these changes
-represent an experiment in print-on-demand delivery of documentation.
-Time will tell whether the experiment succeeded.
-
-Axiom has been in existence for over thirty years. It is estimated to
-contain about three hundred man-years of research and has, as of
-September 3, 2003, 143 people listed in the credits. All of these
-people have contributed directly or indirectly to making Axiom
-available. Axiom is being passed to the next generation. I'm looking
-forward to future milestones.
-
-With that in mind I've introduced the theme of the ``30 year horizon''.
-We must invent the tools that support the Computational Mathematician
-working 30 years from now. How will research be done when every bit of
-mathematical knowledge is online and instantly available? What happens
-when we scale Axiom by a factor of 100, giving us 1.1 million domains?
-How can we integrate theory with code? How will we integrate theorems
-and proofs of the mathematics with space-time complexity proofs and
-running code? What visualization tools are needed? How do we support
-the conceptual structures and semantics of mathematics in effective
-ways? How do we support results from the sciences? How do we teach
-the next generation to be effective Computational Mathematicians?
-
-The ``30 year horizon'' is much nearer than it appears.

-\end{tabular}
-
-\subsection{*eof*}
-The [[*eof*]] variable is set to [[NIL]] in [[ncTopLevel]].
-\subsection{*features*}
-The [[*features*]] variable from common lisp is tested for the presence
-of the [[:unix]] keyword. Apparently this controls the use of Saturn,
-a previous Axiom frontend. The Saturn frontend was never released as
-open source and so this test and the associated variables are probably
-not used.
-
-\subsection{*package*}
-The [[*package*]] variable, from common lisp, is set in [[restart]]
-to the [[BOOT]] package where the intepreter lives.
-\subsection{*standard-input*}
-The [[*standard-input*]] common lisp variable is used to set the
-[[curinstream]] variable in [[ncIntLoop]].
-
-This variable is an argument to [[serverReadLine]] in
-the [[intloopReadConsole]] function.
-
-\subsection{*standard-output*}
-The [[*standard-output*]] common lisp variable is used to set the
-[[curoutstream]] variable in [[ncIntLoop]].
-
-\subsection{*top-level-hook*}
-The [[*top-level-hook*]] common lisp variable contains the name of
-a function to invoke when an image is started. In our case it is
-called [[restart]]. This is the entry point to the Axiom interpreter.

-
-\subsection{\$boot}
-The [[$boot]] variable is set to [[NIL]] in [[ncTopLevel]].
-
-\subsection{coerceFailure}
-The [[coerceFailure]] symbol is a catch tag used in [[runspad]]
-to catch an exit from [[ncTopLevel]].
-
-\subsection{curinstream}
-The [[curinstream]] variable is set to the value of the
-[[*standard-input*]] common lisp
-variable in [[ncIntLoop]]. While not using the
-``dollar'' convention this variable is still ``global''.
-
-\subsection{curinstream}
-The [[curoutstream]] variable is set to the value of the
-[[*standard-output*]] common lisp variable in [[ncIntLoop]].
-While not using the ``dollar'' convention this variable is still ``global''.
-
-\subsection{\$currentLine}
-The [[$currentLine]] line is set to [[NIL]] in [[restart]].
-It is used in [[removeUndoLines]] in the undo mechanism.
-
-\subsection{\$dalymode}
-The [[$dalymode]] variable is used in a case statement in
-[[intloopReadConsole]]. This variable can be set to any non-nil
-value. When not nil the interpreter will send any line that begins
-with an ``[[(]]'' to be sent to the underlying lisp. This is useful
-for debugging Axiom. The normal value of this variable is [[NIL]].
-
-This variable was created as an alternative to prefixing every lisp
-command with [[)lisp]]. When doing a lot of debugging this is tedious
-and error prone. This variable was created to shortcut that process.
-Clearly it breaks some semantics of the language accepted by the
-interpreter as parens are used for grouping expressions.
-
-\subsection{\$defaultMsgDatabaseName}
-The [[$defaultMsgDatabaseName]] is the absolute path to the
-[[s2-us.msgs]] file which contains all of the english language
-messages output by the system.
-
-\subsection{\$directory-list}
-The [[$directory-list]] is a list of absolute directory names.
-These names are made absolute by mapping the [[make-absolute-filename]]
-over the variable [[$relative-directory-list]].
-
-\subsection{\$displayStartMsgs}
-The [[$displayStartMsgs]] variable is used in [[restart]] but is not
-set so this is likely a bug.
-
-\subsection{\$e}
-The [[$e]] variable is set to the value of
-[[$InteractiveFrame]] which is set in [[restart]] to the value of the
-call to the [[makeInitialModemapFrame]] function. This function simply
-returns a copy of the variable [[$InitialModemapFrame]].
-
-Thus [[$e]] is a copy of the variable [[$InitialModemapFrame]].
-
-This variable is used in the undo mechanism.
-
-\subsection{\$erMsgToss}
-The [[$erMsgToss]] variable is set to [[NIL]] in [[SpadInterpretStream]].
-
-\subsection{\$fn}
-The [[$fn]] variable is set in [[SpadInterpretStream]]. It is set to
-the second argument which is a list. It appears that this list has the
-same structure as an argument to the LispVM [[rdefiostream]] function.
-
-\subsection{\$frameRecord}
-[[$frameRecord = [delta1, delta2,... ] ]] where
-[[delta(i)]] contains changes in the ``backwards'' direction.
-Each [[delta(i)]] has the form [[((var . proplist)...)]] where
-proplist denotes an ordinary proplist. For example, an entry
-of the form [[((x (value) (mode (Integer)))...)]] indicates that
-to undo 1 step, [[x]]'s value is cleared and its mode should be set
-to [[(Integer)]].
-
-A [[delta(i)]] of the form [[(systemCommand . delta)]] is a special
-delta indicating changes due to system commands executed between
-the last command and the current command. By recording these deltas
-separately, it is possible to undo to either BEFORE or AFTER
-the command. These special [[delta(i)]]s are given ONLY when a
-a system command is given which alters the environment.
-
-Note: [[recordFrame('system)]] is called before a command is executed, and
-[[recordFrame('normal)]] is called after (see processInteractive1).
-If no changes are found for former, no special entry is given.
-
-This is part of the undo mechanism.
-
-\subsection{\$HiFiAccess}
-The [[$HiFiAccess]] is set by [[initHist]] to [[T]]. It is a flag
-used by the history mechanism to record whether the history function
-is currently on. It can be reset by using the axiom
-command
-\begin{verbatim}
- )history off
-\end{verbatim}
-It appears that the name means ``History File Access''.
-
-The [[$HiFiAccess]] variable is used by [[historySpad2Cmd]] to check
-whether history is turned on. [[T]] means it is, [[NIL]] means it is not.
-
-\subsection{\$HistList}
-Thie [[$HistList]] variable is set by [[initHistList]] to an initial
-value of [[NIL]] elements. The last element of the list is smashed to
-point to the first element to make the list circular.
-This is a circular list of length [[$HistListLen]].
-
-\subsection{\$HistListAct}
-The [[$HistListAct]] variable is set by [[initHistList]] to [[0]].
-This variable holds the actual number of elements in the history list.
-This is the number of ``undoable'' steps.
-
-\subsection{\$HistListLen}
-The [[$HistListLen]] variable is set by [[initHistList]] to [[20]].
-This is the length of a circular list maintained in the variable
-[[$HistList]].
-
-\subsection{\$HistRecord}
-The [[$HistRecord]] variable is set by [[initHistList]] to [[NIL]].
-[[$HistRecord]] collects the input line, all variable bindings
-and the output of a step, before it is written to the file named by
-the function [[histFileName]].
-
-\subsection{\$historyFileType}
-The [[$historyFileType]] is set at load time by a call to
-[[initvars]] to a value of ``[[axh]]''. It appears that this
-is intended to be used as a filetype extension.
-It is part of the history mechanism. It is used in [[makeHistFileName]]
-as part of the history file name.
-
-\subsection{\$inclAssertions}
-The [[$inclAssertions]] is set
-in the function [[SpadInterpretStream]] to the list [[(aix |CommonLisp|)]]
-
-\subsection{\$internalHistoryTable}
-The [[$internalHistoryTable]] variable is set at load time by a call to
-[[initvars]] to a value of [[NIL]].
-It is part of the history mechanism.
-
-\subsection{\$interpreterFrameName}
-The [[$interpreterFrameName]] variable, set in
-[[initializeInterpreterFrameRing]] to the constant
-[[initial]] to indicate that this is the initial (default) frame.
-
-Frames are structures that capture all of the variables defined in a
-session. There can be multiple frames and the user can freely switch
-between them. Frames are kept in a ring data structure so you can
-move around the ring.
-
-\subsection{\$interpreterFrameRing}
-The [[$interpreterFrameRing]] is set to a pair whose car is set to
-the result of [[emptyInterpreterFrame]]
-
-\subsection{\$InitialModemapFrame}
-This variable is copied and returned by the function
-[[makeInitialModemapFrame]]. There is no initial value so this
-is probably a bug.
-
-\subsection{\$inLispVM}
-The [[$inLispVM]] is set to [[NIL]] in [[spad]]. LispVM is a
-non-common lisp that runs on IBM/370 mainframes. This is probably dead
-code. It appears that this list has the same structure as an argument
-to the LispVM [[rdefiostream]] function.
-
-\subsection{\$InteractiveFrame}
-The [[$InteractiveFrame]] is set in [[restart]] to the value of the
-call to the [[makeInitialModemapFrame]] function. This function simply
-returns a copy of the variable [[$InitialModemapFrame]]
-
-\subsection{\$InteractiveMode}
-The [[$InteractiveMode]] is set to [[T]] in [[ncTopLevel]].
-
-\subsection{\$intRestart}
-The [[$intRestart]] variable is used in [[intloop]] but has no value.
-This is probably a bug. While the variable's value is unchanged the
-system will continually reenter the [[SpadInterpretStream]] function.
-
-\subsection{\$intTopLevel}
-The [[$intTopLevel]] is a catch tag. Throwing to this tags which is
-caught in the [[intloop]] will
-restart the [[SpadInterpretStream]] function.
-
-\subsection{\$IOindex}
-The [[$IOindex]] index variable is set to [[1]] in [[restart]].
-This variable is used in the [[historySpad2Cmd]] function in the
-history mechanism. It is set in the [[removeUndoLines]] function
-in the undo mechanism.
-
-This is used in the undo mechanism in function [[undoCount]]
-to compute the number of undos. You can't undo more actions then
-have already happened.
-
-\subsection{\$lastPos}
-The [[$lastPos]] variable is set in [[SpadInterpretStream]]
-to the value of the [[$nopos]] variable.
-Since [[$nopos]] appears to have no value
-this is likely a bug.
-
-\subsection{\$libQuiet}
-The [[$libQuiet]] variable is set to the third argument of the
-[[SpadInterpretStream]] function. This is passed from [[intloop]]
-with the value of [[T]]. This variable appears to be intended to
-control the printing of library loading messages which would need
-to be suppressed if input was coming from a file.
-
-\subsection{\$library-directory-list}
-The [[$library-directory-list]] variable is set by [[reroot]] by
-mapping the function [[make-absolute-filename]] across the
-[[$relative-library-directory-list]] variable which is not yet set so this
-is probably a bug.
-
-\subsection{\$msgDatabaseName}
-The [[$msgDatabaseName]] is set to [[NIL]] in [[reroot]].
-
-\subsection{\$ncMsgList}
-The [[$ncMsgList]] is set to [[NIL]] in [[SpadInterpretStream]].
-
-\subsection{\$newcompErrorCount}
-The [[$newcompErrorCount]] is set to [[0]] in [[SpadInterpretStream]].
-
-\subsection{\$newspad}
-The [[$newspad]] is set to [[T]] in [[ncTopLevel]].
-
-\subsection{\$nopos}
-The [[$nopos]] variable is used in [[SpadInterpretStream]] but does
-not appear to have a value and is likely a bug.
-
-\subsection{\$oldHistoryFileName}
-The [[$oldHistoryFileName]] is set at load time by a call to
-[[initvars]] to a value of ``[[last]]''.
-It is part of the history mechanism. It is used in the function
-[[oldHistFileName]] and [[restoreHistory]].
-
-\subsection{\$okToExecuteMachineCode}
-The [[$okToExecuteMachineCode]] is set to [[T]] in [[SpadInterpretStream]].
-
-\subsection{\$options}
-The [[$options]] variable is tested by the [[history]] function.
-If it is [[NIL]] then output the message
-\begin{verbatim}
- You have not used the correct syntax for the history command.
- Issue )help history for more information.
-\end{verbatim}
-
-The [[$options]] variable is tested in the [[historySpad2Cmd]] function.
-It appears to record the options that were given to a spad command on
-the input line. The function [[selectOptionLC]] appears to take a list
-off options to scan.
-
-This variable is not yet set and is probably a bug.
-
-\subsection{\$previousBindings}
-The [[$previousBindings]] is a copy of the
-[[CAAR $InteractiveFrame]]. This is used to
-compute the [[delta(i)]]s stored in [[$frameRecord]].
-This is part of the undo mechanism.
-
-\subsection{\$PrintCompilerMessageIfTrue}
-The [[$PrintCompilerMessageIfTrue]] variable is set to [[NIL]] in [[spad]].
-
-\subsection{\$openServerIfTrue}
-The [[$openServerIfTrue]] is tested in [[restart]] before it has been
-set (and is thus a bug). It appears to control whether the interpreter
-will be used as an open server, probably for OpenMath use.
-
-If an open server is not requested then this variable to [[NIL]]
-
-\subsection{\$promptMsg}
-The [[$promptMsg]] variable is set to the constant [[S2CTP023]]. This
-constant points to a message in [[src/doc/msgs/s2-us.msgs]]. This message
-does nothing but print the argument value.
-
-\subsection{\$relative-directory-list}
-The [[$relative-directory-list]] is used in [[reroot]] to create
-[[$directory-list]] which is a list of absolute directory names.
-It is not yet set and is probably a bug.
-
-\subsection{\$relative-library-directory-list}
-The [[$relative-library-directory-list]] is used in [[reroot]] to create
-a list of absolute directory names from [[$library-directory-list]] (which is
-It is not yet set and is probably a bug).
-
-\subsection{\$reportUndo}
-The [[$reportUndo]] variable is used in [[diffAlist]]. It was not normally
-bound but has been set to [[T]] in [[initvars]]. If the variable is set
-to [[T]] then we call [[reportUndo]].
-
-It is part of the undo mechanism.
-
-\subsection{\$shoeReadLineFunction}
-The [[$shoeReadLineFunction]] is set in [[SpadInterpretStream]]
-to point to the
-[[serverReadLine]]
-
-\subsection{\$spad}
-The [[$spad]] variable is set to [[T]] in [[ncTopLevel]].
-
-\subsection{\$SpadServer}
-If an open server is not requested then this variable to [[T]].
-It has no value before this time (and is thus a bug).
-
-\subsection{\$SpadServerName}
-The [[$SpadServerName]] is passed to the [[openServer]] function, if the
-function exists.
-
-\subsection{\$systemCommandFunction}
-The [[$systemCommandFunction]] is set in [[SpadInterpretStream]]
-to point to the function
-[[InterpExecuteSpadSystemCommand]].
-
-\subsection{top\_level}
-The [[top\_level]] symbol is a catch tag used in [[runspad]]
-to catch an exit from [[ncTopLevel]].
-
-\subsection{\$quitTag}
-The [[$quitTag]] is used as a variable in a [[catch]] block.
-It appears that it can be thrown somewhere below [[ncTopLevel]].
-
-\subsection{\$useInternalHistoryTable}
-The [[$useInternalHistoryTable]] variable is set at load time by a call to
-[[initvars]] to a value of [[NIL]]. It is part of the history mechanism.
-
-\subsection{\$undoFlag}
-The [[$undoFlag]] is used in [[recordFrame]] to decide whether to do
-undo recording. It is initially set to [[T]] in [[initvars]].
-This is part of the undo mechanism.
-
-\chapter{Starting Axiom}
-Axiom starts by invoking a function value of the lisp symbol
-[[*top-level-hook*]]. The function invocation path to from this
-point until the prompt is approximates (skipping initializations):
-\begin{verbatim}

- -> |runspad|
- -> |ncTopLevel|
- -> |ncIntLoop|
- -> |intloop|
- -> |SpadInterpretStream|

-\chapter{The History Mechanism}
-\section{)history}
-\index{ugSysCmdhistory}
-
-\index{history}
-
-
-\par\noindent{\bf User Level Required:} interpreter
-
-\par\noindent{\bf Command Syntax:}
-\begin{list}{}
-\item{\tt )history )on}
-\item{\tt )history )off}
-\item{\tt )history )write} {\it historyInputFileName}
-\item{\tt )history )show [{\it n}] [both]}
-\item{\tt )history )save} {\it savedHistoryName}
-\item{\tt )history )restore} [{\it savedHistoryName}]
-\item{\tt )history )reset}
-\item{\tt )history )change} {\it n}
-\item{\tt )history )memory}
-\item{\tt )history )file}
-\item{\tt \%}
-\item{\tt \%\%({\it n})}
-\item{\tt )set history on | off}
-\end{list}
-
-\par\noindent{\bf Command Description:}
-
-The {\it history} facility within Axiom allows you to restore your
-environment to that of another session and recall previous
-computational results.
-Additional commands allow you to review previous
-input lines and to create an {\bf .input} file of the lines typed to
-\index{file!input}
-Axiom.
-
-Axiom saves your input and output if the history facility is
-turned on (which is the default).
-This information is saved if either of
-\begin{verbatim}
-)set history on
-)history )on
-\end{verbatim}
-has been issued.
-Issuing either
-\begin{verbatim}
-)set history off
-)history )off
-\end{verbatim}
-will discontinue the recording of information.
-\index{history )on}
-\index{set history on}
-\index{set history off}
-\index{history )off}
-
-Whether the facility is disabled or not,
-the value of {\tt \%} in Axiom always
-refers to the result of the last computation.
-If you have not yet entered anything,
-{\tt \%} evaluates to an object of type
-{\tt Variable('\%)}.
-The function {\tt \%\%} may be used to refer
-to other previous results if the history facility is enabled.
-In that case,
-{\tt \%\%(n)} is the output from step {\tt n} if {\tt n > 0}.
-If {\tt n < 0}, the step is computed relative to the current step.
-Thus {\tt \%\%(-1)} is also the previous step,
-{\tt \%\%(-2)}, is the step before that, and so on.
-If an invalid step number is given, Axiom will signal an error.
-
-The {\it environment} information can either be saved in a file or entirely in
-memory (the default).
-Each frame
-(\ref{ugSysCmdframe} on page~\pageref{ugSysCmdframe})
-has its own history database.
-When it is kept in a file, some of it may also be kept in memory for
-efficiency.
-When the information is saved in a file, the name of the file is
-of the form {\bf FRAME.axh} where ``{\bf FRAME}'' is the name of the
-current frame.
-The history file is placed in the current working directory
-(see \ref{ugSysCmdcd} on page~\pageref{ugSysCmdcd}).
-Note that these history database files are not text files (in fact,
-they are directories themselves), and so are not in human-readable
-format.
-
-The options to the {\tt )history} command are as follows:
-
-\begin{description}
-\item[{\tt )change} {\it n}]
-will set the number of steps that are saved in memory to {\it n}.
-This option only has effect when the history data is maintained in a
-file.
-If you have issued {\tt )history )memory} (or not changed the default)
-there is no need to use {\tt )history )change}.
-\index{history )change}
-
-\item[{\tt )on}]
-will start the recording of information.
-If the workspace is not empty, you will be asked to confirm this
-request.
-If you do so, the workspace will be cleared and history data will begin
-being saved.
-You can also turn the facility on by issuing {\tt )set history on}.
-
-\item[{\tt )off}]
-will stop the recording of information.
-The {\tt )history )show} command will not work after issuing this
-command.
-Note that this command may be issued to save time, as there is some
-performance penalty paid for saving the environment data.
-You can also turn the facility off by issuing {\tt )set history off}.
-
-\item[{\tt )file}]
-indicates that history data should be saved in an external file on disk.
-
-\item[{\tt )memory}]
-indicates that all history data should be kept in memory rather than
-saved in a file.
-Note that if you are computing with very large objects it may not be
-practical to kept this data in memory.
-
-\item[{\tt )reset}]
-will flush the internal list of the most recent workspace calculations
-so that the data structures may be garbage collected by the underlying
-Common Lisp system.
-Like {\tt )history )change}, this option only has real effect when
-history data is being saved in a file.
-
-\item[{\tt )restore} [{\it savedHistoryName}]]
-completely clears the environment and restores it to a saved session, if
-possible.
-The {\tt )save} option below allows you to save a session to a file
-with a given name. If you had issued
-{\tt )history )save jacobi}
-the command
-{\tt )history )restore jacobi}
-would clear the current workspace and load the contents of the named
-saved session. If no saved session name is specified, the system looks
-for a file called {\bf last.axh}.
-
-\item[{\tt )save} {\it savedHistoryName}]
-is used to save a snapshot of the environment in a file.
-This file is placed in the current working directory
-(see \ref{ugSysCmdcd} on page~\pageref{ugSysCmdcd}).
-Use {\tt )history )restore} to restore the environment to the state
-preserved in the file.
-This option also creates an input file containing all the lines of input
-since you created the workspace frame (for example, by starting your
-Axiom session) or last did a {\tt )clear all} or
-{\tt )clear completely}.
-
-\item[{\tt )show} [{\it n}] [{\tt both}]]
-can show previous input lines and output results.
-{\tt )show} will display up to twenty of the last input lines
-(fewer if you haven't typed in twenty lines).
-{\tt )show} {\it n} will display up to {\it n} of the last input lines.
-{\tt )show both} will display up to five of the last input lines and
-output results.
-{\tt )show} {\it n} {\tt both} will display up to {\it n} of the last
-input lines and output results.
-
-\item[{\tt )write} {\it historyInputFile}]
-creates an {\bf .input} file with the input lines typed since the start
-of the session/frame or the last {\tt )clear all} or {\tt )clear
-completely}.
-If {\it historyInputFileName} does not contain a period (``.'') in the filename,
-{\bf .input} is appended to it.
-For example,
-{\tt )history )write chaos}
-and
-{\tt )history )write chaos.input}
-both write the input lines to a file called {\bf chaos.input} in your
-current working directory.
-If you issued one or more {\tt )undo} commands,
-{\tt )history )write}
-eliminates all
-input lines backtracked over as a result of {\tt )undo}.
-You can edit this file and then use {\tt )read} to have Axiom process
-the contents.

-
-History recording is done in two different ways:
-\begin{itemize}
-\item all changes in variable bindings (i.e. previous values) are
- written to [[$HistList]], which is a circular list
-\item all new bindings (including the binding to [[%]]) are written to a
- file called [[histFileName()]]
- one older session is accessible via the file [[$oldHistFileName()]]
-\end{itemize}
-
-\section{Variables Used}
-The following global variables are used:
-\begin{list}{}
-\item [[$HistList]], [[$HistListLen]] and [[$HistListAct]] which is the
- actual number of ``undoable'' steps)
-\item [[$HistRecord]] collects the input line, all variable bindings
- and the output of a step, before it is written to the file
- [[histFileName()]].
-\item [[$HiFiAccess]] is a flag, which is reset by [[)history )off]]
-\end{list}
-The result of step n can be accessed by [[%n]], which is translated
-into a call of [[fetchOutput(n)]]. The
-[[updateHist]] is called after every interpreter step. The
-[[putHist]] function records all changes in the environment to [[$HistList]]
- and [[$HistRecord]]

-A {\it frame} can be thought of as a logical session within the
-physical session that you get when you start the system. You can
-have as many frames as you want, within the limits of your computer's
-storage, paging space, and so on.

-You can have a variable named {\tt a} in one frame and it will
-have nothing to do with anything that might be called {\tt a} in
-any other frame.

- The %1b system command takes arguments but no options.
-S2IZ0017
- %1b is not a valid frame name
-S2IZ0018
- You must provide a name for the new frame.
-S2IZ0019
- You cannot use the name %1b for a new frame because an existing
- frame already has that name.
-S2IZ0020
- There is only one frame active and therefore that cannot be closed.
- Furthermore, the frame name you gave is not the name of the current frame.
- The current frame is called %1b .
-S2IZ0021
- The current frame is the only active one. Issue %b )clear all %d to
- clear its contents.
-S2IZ0022
- There is no frame called %1b and so your command cannot be
- processed.
-S2IZ0024
- The names of the existing frames are: %1 %l
- The current frame is the first one listed.
-S2IZ0073
- %b )frame import %d must be followed by the frame name. The names
- of objects in that frame can then optionally follow the frame name.
- For example,
- %ceon %b )frame import calculus %d %ceoff
- imports all objects in the %b calculus %d frame, and
- %ceon %b )frame import calculus epsilon delta %d %ceoff
- imports the objects named %b epsilon %d and %b delta %d from the
- frame %b calculus %d .
- Please note that if the current frame contained any information
- about objects with these names, then that information would be
- cleared before the import took place.
-S2IZ0074
- You cannot import anything from the frame %1b because that is not
- the name of an existing frame.
-S2IZ0075
- You cannot import from the current frame (nor is there a need!).
-S2IZ0076
- User verification required:
- do you really want to import everything from the frame %1b ?
- If so, please enter %b y %d or %b yes %d :
-S2IZ0077
- On your request, OpenAxiom will not import everything from frame %1b.
-S2IZ0078
- Import from frame %1b is complete. Please issue %b )display all %d
- if you wish to see the contents of the current frame.
-S2IZ0079
- OpenAxiom cannot import %1b from frame %2b because it cannot be found.

-\par\noindent{\bf User Level Required:} interpreter
-
-\par\noindent{\bf Command Syntax:}
-\begin{list}{}
-\item{\tt )undo}
-\item{\tt )undo} {\it integer}
-\item{\tt )undo} {\it integer [option]}
-\item{\tt )undo} {\tt )redo}
-\end{list}
-%
-where {\it option} is one of
-%
-\begin{list}{}
-\item{\tt )after}
-\item{\tt )before}
-\end{list}
-
-\par\noindent{\bf Command Description:}
-
-This command is used to
-restore the state of the user environment to an earlier
-point in the interactive session.
-The argument of an {\tt )undo} is an integer which must designate some
-step number in the interactive session.
-
-\begin{verbatim}
-)undo n
-)undo n )after
-\end{verbatim}
-These commands return the state of the interactive
-environment to that immediately after step {\tt n}.
-If {\tt n} is a positive number, then {\tt n} refers to step nummber
-{\tt n}. If {\tt n} is a negative number, it refers to the \tt n-th
-previous command (that is, undoes the effects of the last $-n$
-commands).
-
-A {\tt )clear all} resets the {\tt )undo} facility.
-Otherwise, an {\tt )undo} undoes the effect of {\tt )clear} with
-options {\tt properties}, {\tt value}, and {\tt mode}, and
-that of a previous {\tt undo}.
-If any such system commands are given between steps $n$ and
-$n + 1$ ($n > 0$), their effect is undone
-for {\tt )undo m} for any $0 < m \leq n$..
-
-The command {\tt )undo} is equivalent to {\tt )undo -1} (it undoes
-the effect of the previous user expression).
-The command {\tt )undo 0} undoes any of the above system commands
-issued since the last user expression.
-
-\begin{verbatim}
-)undo n )before
-\end{verbatim}
-This command returns the state of the interactive
-environment to that immediately before step {\tt n}.
-Any {\tt )undo} or {\tt )clear} system commands
-given before step {\tt n} will not be undone.
-
-\begin{verbatim}
-)undo )redo
-\end{verbatim}
-This command reads the file {\tt redo.input}.
-created by the last {\tt )undo} command.
-This file consists of all user input lines, excluding those
-backtracked over due to a previous {\tt )undo}.
-
-\par\noindent{\bf Also See:}
-{\tt )history} \index{ugSysCmdhistory}.
-The command {\tt )history )write} will eliminate the ``undone'' command
-lines of your program.
-\section{Variables Used}
-\section{Data Structures}
-[[$frameRecord = [delta1, delta2,... ] ]] where
-[[delta(i)]] contains changes in the ``backwards'' direction.
-Each [[delta(i)]] has the form [[((var . proplist)...)]] where
-proplist denotes an ordinary proplist. For example, an entry
-of the form [[((x (value) (mode (Integer)))...)]] indicates that
-to undo 1 step, [[x]]'s value is cleared and its mode should be set
-to [[(Integer)]].
-
-A [[delta(i)]] of the form [[(systemCommand . delta)]] is a special
-delta indicating changes due to system commands executed between
-the last command and the current command. By recording these deltas
-separately, it is possible to undo to either BEFORE or AFTER
-the command. These special [[delta(i)]]s are given ONLY when a
-a system command is given which alters the environment.
-
-Note: [[recordFrame('system)]] is called before a command is executed, and
-[[recordFrame('normal)]] is called after (see processInteractive1).
-If no changes are found for former, no special entry is given.
-
-The [[$previousBindings]] is a copy of the
-[[CAAR $InteractiveFrame]]. This is used to
-compute the [[delta(i)]]s stored in [[$frameRecord]].

-\chapter{Axiom Build-time Functions}
-\subsection{defun spad-save}
-The {\bf spad-save} function is just a cover function for more
-lisp system specific save functions. There is no standard name
-for saving a lisp image so we make one and conditionalize it
-at compile time.
-
-This function is passed the name of an image that will be saved.
-The saved image contains all of the loaded functions.
-
-This is used in the [[src/interp/Makefile.pamphlet]] in three places:
-\begin{list}{}
-\item creating depsys, an image for compiling axiom.
-
-Some of the Common Lisp code we compile uses macros which
-are assumed to be available at compile time. The {\bf DEPSYS}
-image is created to contain the compile time environment
-and saved. We pipe compile commands into this environment
-to compile from Common Lisp to machine dependent code.
-\begin{verbatim}
-DEPSYS= ${OBJ}/${SYS}/bin/depsys
-\end{verbatim}
-
-\item creating savesys, an image for running axiom.
-
-Once we've compile all of the Common Lisp files we fire up
-a clean lisp image called {\bf LOADSYS}, load all of the
-final executable code and save it out as {\bf SAVESYS}.
-The {\bf SAVESYS} image is copied to the [[${MNT}/${SYS}/bin]]
-subdirectory and becomes the axiom executable image.
-\begin{verbatim}
-LOADSYS= ${OBJ}/${SYS}/bin/lisp
-SAVESYS= ${OBJ}/${SYS}/bin/interpsys
-AXIOMSYS= ${MNT}/${SYS}/bin/AXIOMsys
-\end{verbatim}
-
-
-\item creating debugsys, an image with all interpreted functions loaded.
-
-Occasionally we need to really get into the system internals.
-The best way to do this is to run almost all of the lisp code
-interpreted rather than compiled (note that cfuns.lisp and sockio.lisp
-still need to be loaded in compiled form as they depend on the
-loader to link with lisp internals). This image is nothing more
-than a load of the file src/interp/debugsys.lisp.pamphlet. If
-you need to make test modifications you can add code to that
-file and it will show up here.
