controls whether arrays are printed readably. If the value of this variable is nil, the contents of arrays other than strings are never printed.

*PRINT-BASE*
 
@d[@iVariable@d]

@d[@iFunction@d]
prints information about the call history to *debug-io*. 

*PRINT-CASE*
 
@d[@iVariable@d]
controls the case used for printing symbols. The value of *print-case* should be :upcase (the default), :downcase, or :capitalize.

*PRINT-CIRCLE*
 
@d[@iVariable@d]
Controls the printing of data objects which may be circular, such as arrays and lists. If *print-circle* is true, then the printer checks for circular structures (which makes printing slower). The default is nil.

*PRINT-ESCAPE*
 
@d[@iVariable@d]
controls the printing of escape characters. If @p*print-escape*@d is true (the default), then escape characters are printed (which increases the chances that objects will print readably).

*PRINT-GENSYM*

@d[@iVariable@d]
controls how many elements of a list or array are printed. If nil, then the entire data structure is printed.

*PRINT-LEVEL*
 
@d[@iVariable@d]
controls how many levels of a list or array are printed. If nil, then all levels are printed.

*PRINT-LINES*
 
@d[@iVariable@d]

PRINT-OBJECT
@iobject@p @istream@d
[@iGeneric@p @iFunction@d]
writes the printed representation of @iobject@d to @istream@d.  This may be specialized, but should not be called by the user.  Methods should implement appropriate semantics for printer control variables.

*PRINT-PPRINT-DISPATCH*
 
@d[@iVariable@d]
is bound to a dispatch table for the pretty printer. Normally modified using@p SET-PPRINT-DISPATCH@d.

*PRINT-PRETTY*
 
@d[@iVariable@d]
controls the look of printed expressions. If true, then extra whitespace is inserted to make the printed representation of forms more readable. For a description of user-controlled pretty-printing in Common Lisp, see@i Common@d @iLisp:@d @iThe@d @iLanguage,@d 2d edition, Chapter 27.

*PRINT-RADIX*
 
@d[@iVariable@d]
controls the printing of radix specifiers for rational numbers. If true, then rational numbers are printed with radix specifiers. This ensures that the numbers may be read back into Lisp. The default is nil.

*PRINT-READABLY*
 
@d[@iVariable@d]
If this Common Lisp variable true, objects are printed out such that the printed representation can be read back into Lisp to create a similar object. If false, objects may be printed more tersely.

PRINT-RECORD
@irecord@d @irecord-type@d &optional@i currlevel@d 
[@iFunction@d]
prints the values of the fields of@i record@d with type@i record-type@d to *standard-output*.

@iqueue@p &optional @iqueue-owner@p @i(whostate "Lock")@d
[@iFunction@d]
adds a process to a @iqueue@d. If the @iqueue@d is empty, the process becomes the owner of the @iqueue@d, and the function returns. If @iqueue@d is not empty and not full, the function adds the process to the end of @iqueue@d. The @pPROCESS-ENQUEUE@d function waits until the process reaches the front of the @iqueue@d and becomes the owner of the @iqueue@d. If @iqueue@d is full, @pPROCESS-ENQUEUE@d waits until @iqueue@d is not full before adding the process to the end of @iqueue@d. By default, the process added to the @iqueue@d is the current process. The optional argument @iqueue-owner@d specifies a different process to place on the @iqueue@d. If the process is already on the @iqueue@d, an error is signaled. The value of @iqueue-owner@d is compared using the @pEQ@d function.  The string @iwhostate@d describes the reason for waiting.

process-enqueue-with-timeout
@iqueue@p &optional @iqueue-owner@p @i(whostate "Lock")@d
[@iFunction@d]
adds a process to a @iqueue@d. If the @iqueue@d is empty, the process becomes the owner of the @iqueue@d, and the function returns. If @iqueue@d is not empty and not full, the function adds the process to the end of @iqueue@d. The @pPROCESS-ENQUEUE@d function waits until the process reaches the front of the @iqueue@d and becomes the owner of the @iqueue@d. If the process does not reach the front of the @iqueue@d within the time interval @itimeout@d, the process is dequeued. If @iqueue@d is full, @pPROCESS-ENQUEUE@d waits until @iqueue@d is not full before adding the process to the end of @iqueue@d. By default, the process added to the @iqueue@d is the current process. The optional argument @iqueue-owner@d specifies a different process to place on the @iqueue@d. If the process is already on the @iqueue@d, an error is signaled. The value of @iqueue-owner@d is compared using the @pEQ@d function.  The string @iwhostate@d describes the reason for waiting.

process-preset
@iprocess@p @ifunction@p &rest @iargs@d
[@iFunction@d]
sets the initial function of @iprocess@d to @ifunction@d and the initial arguments to @iargs@d. The @iprocess@d is reset so that it throws out of its present computation and starts up by applying @ifunction@d to @iargs@d. If this function is called for a stopped @iprocess@d, the @iprocess@d is not activated.

process-priority

This is the default value.); @p:always@d (Unwind always. This can cause the function @pPROCESS-RESET@d to throw through its caller rather than returning.); @pt@d (Never rewinds.); @pkill@d (An argument specifying whether to kill a process after unwinding. The possible values for this argument are @p:kill@d and @pnil@d. If @ikill@d is @p:kill@d, the process is killed after unwinding.) The default is nil. MCL currently ignores @iwithout-aborts@d.

REQUIRE-TYPE
@iargument@d @itype@d
[@iFunction@d]
like the Common Lisp check-type macro, except that it returns a value rather than using setf, and so can be done entirely out-of-line. If@i argument@d is of the same type as@i type@d, require-type returns@i argument.@d If not, it returns an error.

RESTART-BIND
@p(@i{@p(@iname@p @ifunction@p @i{@p:interactive-function @iinteractive-func | @p:report-function @ireport-func | @p:test-function @itest-func}*@p)@i}@p) @iform*@d
[@iMacro@d]
executes @iform@ds in a dynamic environment where restart named @iname@d (or an anonymous restart if @iname@d is @pNIL@d) is in effect.  The @ifunction@d and @i...-func@d forms are all evaluated in the current environment before any of the @iform@ds.  When @pINVOKE-RESTART@d is called, the function returned by @ifunction@d is invoked with the arguments passed to @iINVOKE-RESTART@d; the function may return normally or transfer control.  If a restart is invoked from the debugger (via @pINVOKE-RESTART-INTERACTIVELY@d) then the @i...-func@ds modify the behavior of the restart.  The restart is visible if the function returned by @itest-func@d returns true.  The arguments passed to @ifunction@d are defaulted by the result of the function returned by @iinteractive-func@d.  The description of actions taken by the restart are printed by the function returned by @ireport-func@d; the function should expect a @pSTREAM@d argument.  @pRESTART-BIND@d returns the values produced by the @iform@ds.

RESTART-CASE

@i[Macro@d]
executes @irestartable-form@d in a dynamic environment where restarts named @icase-name@d are in effect.  If @restartable-form@d transfers controls to one of the restarted named by @icase-name@ds, then the values returned by @iform@ds of that case are returned by @pRESTART-CASE@d.  If a restart is invoked from the debugger (via @pINVOKE-RESTART-INTERACTIVELY@d) then the @i...-exp@ds modify the behavior of the restart.  The restart is visible if the function returned by @itest-exp@d returns true; the test function expects a @pCONDITION@d as its argument.  The arguments passed to @ilambda-list@d of the restart case are defaulted by the result of the function returned by @iinteractive-exp@d.  The description of actions taken by the restart are printed by the @ireport-exp@d function, which expects a @pSTREAM@d argument.  If @irestartable-form@d does not invoke a restart, its values are returned by @pRESTART-CASE@d.

RESTART-NAME
@irestart@d
[@iFunction@d]
returns the name of @irestart@d, or @pNIL@d if @irestart@d is anonymous.

ROUND
@inumber@d &optional@i divisor
@d[@iFunction@d]
returns the integer nearest to@i number.@d If@i number@d is halfway between two integers (for example 3.5), round converts@i number@d to the nearest integer divisible by 2. round returns a second value, which is the remainder of the rounding operation. When there is a second argument, round first divides@i divisor@d into@i number@d, and then applies round to the result.

ROW-MAJOR-AREF
@iarray@p @iindex@d
[@iFunction@d]
returns the @iindex@dth element of @iarray@d, treating array as a vector with elements in row-major order.  May be used with @pSETF@d.

@dcreates a stand-alone image containing the functionality of the current Lisp environment.@p @dWhen@p save-application @dis finished, Lisp exits to the Finder.

*SAVE-DEFINITIONS*
 
@d[@iVariable@d]
if the value of this variable is@p t@d, the lambda expression used to generate functions is retained. This allows compiled functions to be uncompiled. If@p nil@d, the lambda expression is not saved (which saves space). Only functions with saved definitions can be stepped.

*SAVE-DOC-STRINGS*
 
@d[@iVariable@d]
if the value of this variable is@p t@d, documentation strings of definitions are retained; if@p nil@d, documentation strings are discarded. Documentation strings take up memory, so setting@p *save-doc-strings* @dto@p nil @dcan save space. The documentation strings can be accessed through the function@p documentation@d, and through the Fred command Control-X Control-D.

*SAVE-EXIT-FUNCTIONS*
 
@d[@iVariable@d]@p
@da list of functions to be called when an image is dumped, or when an application is saved.@p @dThese functions should perform any preparation necessary for the dump.

if true, Fred window positions, sizes, and font-information are saved and restored between editing sessions.@b

*SAVE-LOCAL-SYMBOLS*
 
@d[Variable]
if true, compiled functions retain the names of parameters and local variables, for debugging purposes.@b

*SAVE-POSITION-ON-WINDOW-CLOSE*
 
@d[@iVariable@d]
determines when the editor saves information about the size, position, beginning line, cursor position, and selection of the Fred window. If the value of this variable is@p nil @d(the default), and@p *save-fred-window-positions* @dis true (the default), then this information is saved only when the file is saved. If the value of this variable is true, then Fred saves this information whenever the window is closed. Hence, each time you open an MCL file, it appears as it did the last time someone looked at it.

SBIT
@isimple-bit-array@p &rest@i subscripts@d
[@iFunction@d]
returns the bit in@i simple-bit-array@p @dindicated by the@i subscripts.@p @dThis function can be used with@p setf @dto destructively replace a bit-array element.@i

[@iMacro@d]
@imname@p @dis defined as if by@p macrolet @dwith@i form@ds as its lexical scope, such that each invocation of (@imname@d) returns a symbol. Successive invocations eventually deliver all the symbols matching@i symbol-type@ds from the packages that are the elements of@i package-list@d,@p @dwhich is evaluated exactly once. Each invocation of@i mname@p @dreturns@p nil @dif there are no more symbols to be processed in the current package. If symbols remain to be processed, the function returns four values:@p t@d, the symbol, a keyword indicating its accessibility, and the package from which it was accessed.

WITH-RETURNED-PSTRS
@d(@p{@d(@isymbol@p @istring@d)@p}@d+)@p {@iform@p}@d+ 
[@iMacro@d]
allocates 256 bytes for each@i string@d,@p @dstores@i string@p @din this memory in the Pascal string format, and binds the corresponding@i symbol@p @dto a pointer to the memory. The memory slots are guaranteed to be large enough to hold returned strings.

WITH-RGB
@d(@ivariable@p @icolor@d) {@iform@d}*
[@iMacro@d]
executes@i forms@p @dwith@i variable@p @dbound to an RGB color record equivalent to@i color@d.@p @dThe record is automatically deallocated when the@i body-forms@p @dexit.@b

WITH-SIMPLE-RESTART
@p(@iname@p @iformat-control@p @iformat-argument*@p) @iform8@d
[@iMacro@d]
establishes a restart with the given @iname@d (or an anonymous restart if @iname@d is @pNIL@d), then executes @iform@ds.  If the restart is invoked, @iformat-control@d and @iformat-argument@ds are used to report the restart, then @iWITH-SIMPLE-RESTART@p returns the values @pNIL@d and @pT@d.  If the restart is not invoked, @pWITH-SIMPLE-RESTART@d returns the values of the last @iform@d.

WITH-SLOTS
@p(@i@islot-entry*@p) @iinstance-form@p @ideclaration*@p @iform*@d
[@iMacro@d]
executes @iform@ds with some slots of the object named by @iinstance-form@d accessible as if they were lexical variables.

with-process-enqueued
@p(@iqueue@p &optional @iqueue-owner@p @iwhostate@p @i(signal-dequeue-errors t)@p) &body @ibody@d
[@iMacro@d]
executes @ibody@d while @iqueue@d is controlled by @iqueue-owner@d. After executing @ibody@d, @iqueue-owner@d relinquishes control of @iqueue@d. The @iqueue-owner@d defaults to the current process.  The string @iwhostate@ describes the reason for which the process is enqueued. When @isignal-dequeue-errors@d is true (the default), an error is signaled if @iqueue-owner@d does not control @iqueue@d when @pPROCESS-DEQUEUE@d is called on exiting @pWITH-PROCESS-ENQUEUE@d.

@p&body@i body@p
@d[@iSpecial@p @iForm@d]
executes@i body@p @dwith all event processing disabled.
