CLIPS typically will display two kinds of error messages: those associated with executing constructs and those associated with loading constructs. This appendix describes some of the more common error messages and what they mean. Each message begins with a unique identifier enclosed in brackets; the messages are listed here in alphabetic order according to the identifier.[AGENDA1] Salience value must be an integer value.

Salience requires a integer argument and will otherwise result in this error message.

Example:

CLIPS> (defrule error (declare (salience a)) =>)[AGENDA2] Salience value out of range <min> to <max>

The range of allowed salience has an explicit limit; this error message will result if the value is out of that range.

Example:

CLIPS> (defrule error (declare (salience )) =>)[AGENDA3] This error occurred while evaluating the salience [for rule <name>]

When an error results from evaluating a salience value for a rule, this error message is given.[ANALYSIS1] Duplicate patternaddress <variable name> found in CE <CE number>.

This message occurs when two facts or instances are bound to the same patternaddress variable.

Example:

CLIPS> (defrule error ?f <- (a) ?f <- (b) =>)[ANALYSIS2] Patternaddress <variable name> used msg 0.0 error atmospheric fusionworks renderer CE #2 was previously bound within a pattern CE.

A variable first bound within a pattern cannot be later bound to a factaddress.

Example:

CLIPS> (defrule error (a ?f) ?f <- (b) =>)[ANALYSIS3] Variable <variable name> is used as both a single and multifield variable.

Variables on the LHS of a rule cannot be bound to both single and multifield variables.

Example:

CLIPS> (defrule error (a ?x $?x) =>) [ANALYSIS4] Variable <variable name> [found in the expression <expression>]was referenced in CE <CE number> <field or slot identifier> before being defined

A variable cannot be referenced before it is error invalid function or declaration and, thus, results in this error message.

Example:

CLIPS> (defrule foo (a ~?x) =>)[ARGACCES1] Function <name> expected at least <minimum> and no more than <maximum> argument(s)

This error occurs when a function receives less than the minimum number or more than the maximum number of argument(s) expected.[ARGACCES2] Function <functionname> was unable to open file <filename>

This error occurs when the specified function cannot open a file.[ARGACCES3] Function <name1> received a request from function <name2> for argument #<number> which is nonexistent

This error occurs when a function is passed fewer arguments than were expected.[ARGACCES4] Function <name> expected exactly <number> argument(s)

This error occurs when a function that expects a precise number of argument(s) receives an incorrect number of arguments.[ARGACCES4] Function <name> expected at least <number> argument(s)

This error occurs when a function does not receive the minimum number of argument(s) that it expected.[ARGACCES4] Function <name> expected no more than <number> argument(s)

This error occurs when a function receives more than the maximum number of argument(s) expected.[ARGACCES5] Function <name> expected argument #<number> to be of type <datatype>

This error occurs when a function is passed the wrong type of argument.[ARGACCES6] Function <name1> received a request from function <name2> for argument #<number> which is not of type <datatype>

This error occurs when a function requests from another function the wrong type of argument, typically a string or symbol, when expecting a number or vice versa.[BLOAD1] Cannot load <construct type> construct with binary load in effect.

If the bload command was used to load in a binary image, then the named construct cannot be entered until a clear command has been performed to remove the binary image.[BLOAD2] File <filename> is not a binary construct file

This error occurs when the bload command is used to load a file that was not created with the bsave command.[BLOAD3] File <filename> is an incompatible binary construct file

This error occurs when the bload command is used to load a file that error creating stand alone game maker created with the bsave command using a different version of CLIPS.[BLOAD4] Error invalid function or declaration CLIPS environment could not be sprers.eu load cannot continue.

A binary load cannot be performed unless the current CLIPS environment can be cleared.[BLOAD5] Some constructs are still in use by the current binary image:
<constructname 1>
<constructname 2>

<constructname N>Binary <operation> cannot continue.

This error occurs when the current binary image cannot be cleared because some constructs are still being error invalid function or declaration. The <operation> in progress may either be a binary load or a binary clear.[BLOAD6] The following undefined functions are referenced by this binary image:
<functionname 1>
<functionname 2>

<functionname N>

This error error invalid function or declaration when a binary image is loaded that error invalid function or declaration functions which were available in the CLIPS executable that originally created the binary image, but which are not available in the CLIPS executable that is loading the binary image.[BSAVE1] Cannot perform a binary save while a binary load is in effect.

The bsave command does not work when a binary image is loaded.[CLASSEXM1] Inherited slot <slotname> from class <slotname> is not valid for function slotpublicp

This error message occurs when the function slotpublicp is given an inherited slot. This function can only be used on slots defined in the given class.

Example:

CLIPS> (defclass FOO (is-a USER) (slot woz (visibility private))) CLIPS> (defclass BAR (is-a FOO)) CLIPS> (slot-publicp BAR woz)[CLASSFUN1] Unable to find class <class name> in function <function name>. error invalid function or declaration This error message occurs when a function is given a nonexistent class name.

Example:

CLIPS> (class-slots FOO)[CLASSFUN2] Maximum number of simultaneous class hierarchy traversals exceeded <number>, error invalid function or declaration.

This error is usually caused by too many simultaneously active instanceset queries, e.g., doforallinstances. The direct or indirect nesting of instanceset query functions is limited in the following way:

Ci is the number of members in an instanceset for the ith nested instanceset query function.

N is the number of nested instanceset query functions.

<= (the default upper limit)

Example:

CLIPS> (deffunction my-func () (do-for-instance ((?a USER) (?b USER) (?c USER)) TRUE (printout t ?a " " ?b " " ?c crlf)) ; The sum here is C1 = demrad kalisto f5 error which is OK. CLIPS> (do-for-all-instances ((?a OBJECT) (?b OBJECT)) TRUE (my-func)) ; The sum here is C1 + C2 = 2 + 3 = 5 which is OK.

The default upper limit of should be sufficient for most if not all applications. However, the limit may be increased by editing the header file OBJECT.H and recompiling CLIPS.[CLASSPSR1] An abstract class cannot be reactive.

Only concrete error invalid function or declaration can be reactive.

Example:

CLIPS> (defclass FOO (is-a USER) (role stop error code 0x1a_41790 (pattern-match reactive))[CLASSPSR2] Cannot redefine a predefined system class.

Predefined system classes cannot be modified by the user.

Example:

CLIPS> (defclass STRING (is-a NUMBER))[CLASSPSR3] <name> class cannot be redefined while outstanding references to it still exist.

This error occurs when an attempt to redefine a class is made under one or both of the following two circumstances:

1) The class (or any of its subclasses) has instances.

2) The class (or any of its subclasses) appear in the parameter restrictions of any generic function method.

Before the class can be redefined, all such instances and methods must be deleted.

Example:

CLIPS> (defclass A (is-a USER)) CLIPS> (defmethod foo ((?a A LEXEME))) CLIPS> (defclass A (is-a OBJECT)))[CLASSPSR4] Class <attribute> already declared.

Only one specification of a class attribute is allowed.

Example:

CLIPS> (defclass A (is-a USER) (role abstract) (role concrete))[CLSLTPSR1] Duplicate slots not allowed.

Slots in a defclass must be unique.

Example:

CLIPS> (defclass A (is-a USER) (slot foo) (slot foo))[CLSLTPSR2] <name> facet already specified.

Only one occurrence of a facet per slot is allowed.

Example:

CLIPS> (defclass A (is-a USER) (slot foo (access read-only) (access read-write)))[CLSLTPSR3] Cardinality facet can only be used with multifield slots

Autocad civil 3d error 1406 slots by definition have a cardinality of one.

Example:

CLIPS> (defclass A (is-a USER) (slot foo (cardinality 3 5)))[CLSLTPSR4] readonly slots must have a default value

Since slots cannot be unbound and readonly slots cannot be set after initial creation of the instance, readonly slots must have a default value.

Example:

CLIPS> (defclass A (is-a USER) (slot foo (access read-only) (default ?NONE)))[CLSLTPSR5] readonly slots cannot have a write accessor

Since readonly slots cannot be changed after initializationof mysql error message access denied for user instance, a write accessor (put messagehandler) is not allowed.

Example:

CLIPS> (defclass A (is-a USER) (slot foo (access read-only) (create-accessor write)))[CLSLTPSR6] noinherit slots cannot also be public

noinherit slots are by definition not accessible to subclasses and thus only visible to the parent class.

Example:

CLIPS> (defclass A (is-a USER) (slot foo (propagation no-inherit) (visibility public)))[COMMLINE1] Expected a '(', constant, or global variable

This message occurs when a toplevel command does not begin with a '(', error invalid function or declaration, constant, or global variable.

Error invalid function or declaration

CLIPS> ) [COMMLINE2] Expected a command.

This message occurs when a toplevel command is not a symbol.

Example:

CLIPS> ("facts"[CONSCOMP1] Invalid file name <fileName> contains '.'

A '.' cannot be error invalid function or declaration in the file name prefix that is passed to the constructstoc command since this prefix is used to generate file names and some operating systems do not allow more than one '.' to appear in a file name.[CONSTRCT1] Some constructs are still in use. Clear cannot continue.

This error occurs when the clear command is issued when a construct is in use (such as a rule that is firing).[CSTRCPSR1] Expected the beginning of a construct.

This error occurs when the load command expects a left parenthesis followed a construct type and these token types are not found.[CSTRCPSR2] Missing name for <constructtype> construct

This error occurs when the name is missing for a construct that requires a name.

Example:

CLIPS> (defgeneric ())[CSTRCPSR3] Cannot define <constructtype> <constructname> because of an import/export e398 phone code sig error.

or[CSTRCPSR3] Cannot define defmodule <defmodulename> because of an import/export conflict ibm bios error 0662 by the <constructtype> <constructname>.

A construct cannot be defined if defining the construct would allow two different definitions of the same construct type and name to both be visible to any module.

Example:

CLIPS> (defmodule MAIN (export ?ALL)) CLIPS> (deftemplate MAIN::foo) CLIPS> (defmodule BAR (import MAIN ?ALL)) CLIPS> (deftemplate BAR::foo (slot x))[CSTRCPSR4] Cannot redefine <constructtype> <constructname> while it is in use.

A construct cannot be redefined while it is being used by another construct or other data structure (such as a fact or instance).

Example:

CLIPS> (clear) CLIPS> (deftemplate bar) CLIPS> (assert (bar)) <Fact-0> CLIPS> (deftemplate (bar (slot x)))[CSTRNCHK1] Message Varies

This error ID covers a range of messages indicating a type, value, range, or cardinality violation.

Example:

CLIPS> (deftemplate foo (slot x (type SYMBOL))) CLIPS> (assert (foo (x 3)))[CSTRNPSR1] The <first attribute name> attribute conflicts with the <second attribute name> attribute.

This error message occurs when two slot attributes conflict.

Example:

CLIPS> (deftemplate foo (slot x (type SYMBOL) (range 0 2)))[CSTRNPSR2] Minimum <attribute> value must be less thanor equal to the maximum <attribute> value.

The minimum attribute value for the range and cardinality attributes must be less than or equal to the maximum attribute value for the attribute.

Example:

CLIPS> (deftemplate foo (slot x (range 8 1)))[CSTRNPSR3] The <first attribute name> attribute cannot be used in conjunction with the <second attribute name> attribute.

The use of some slot attributes excludes the use of other slot attributes.

Example:

CLIPS> (deftemplate foo (slot x (allowed-values a) (allowed-symbols b)))[CSTRNPSR4] Value does not match the expected type for the <attribute name> attribute.

The arguments to an attribute must match the type expected for that attribute (e.g. error invalid function or declaration must be used for the allowedintegers attribute).

Example:

CLIPS> (deftemplate example (slot x (allowed-integers )))[CSTRNPSR5] The cardinality attribute can only be used with multifield slots.

The cardinality attribute can only be used for slots defined with the multislot keyword, error invalid function or declaration.

Example:

CLIPS> (deftemplate foo (slot x (cardinality 1 1)))[DEFAULT1] The error 27 terminal services value for a single field slot must be a single field value

This error occurs when the default or defaultdynamic error invalid function or declaration for a singlefield slot does not contain a single value or an expression returning a single value.

Example:

CLIPS> (deftemplate error (slot x (default)))[DFFNXPSR1] Deffunctions are not allowed to replace constructs.

A deffunction cannot have the same name as any construct.

Example:

CLIPS> (deffunction defgeneric ())[DFFNXPSR2] Deffunctions are not allowed to replace external functions.

A deffunction cannot have the same name as any system or userdefined external function.

Example:

CLIPS> (deffunction + ())[DFFNXPSR3] Deffunctions are not allowed to replace generic functions.

A deffunction cannot have the same name as any generic function.

Example:

CLIPS> (defgeneric foo) CLIPS> (deffunction foo ())[DFFNXPSR4] Deffunction <name> may not be redefined while it is executing.

A deffunction can be loaded at any time except when a deffunction of the same name is already executing.

Example:

CLIPS> (deffunction foo () (build "(deffunction foo ())")) CLIPS> (foo)

[DFFNXPSR5] Defgeneric <name> imported from module <module name> conflicts with this deffunction.

A deffunction cannot have the same name as any generic function imported from another module.

Example:

CLIPS> (defmodule MAIN (export ?ALL)) CLIPS> (defmethod foo ()) CLIPS> (defmodule FOO (import MAIN ?ALL)) CLIPS> (deffunction foo)[DRIVE1] This error occurred in the join network Problem resides in join #<patternnumber> in rule(s): <problemrules>+

This error pinpoints other evaluation errors associated with evaluating an expression within the join network. The specific pattern of the problem rules is identified.[EMATHFUN1] Domain error for <functionname> function

This error occurs when an argument passed to a math function is not in the domain of values for which a return value exists.[EMATHFUN2] Argument overflow for <functionname> function

This error occurs when an argument to an extended math function would cause a numeric overflow.[EMATHFUN3] Singularity at asymptote in <functionname> function

This error occurs when an argument to a trigonometric math function would cause a singularity.[EVALUATN1] Variable <name> is unbound

This error occurs when a local variable not set by a previous call to bind is accessed at the top level.

Example:

CLIPS> (progn ?error)[EVALUATN2] No function, generic function or deffunction of name <name> exists for external call. IThis error occurs only when an invalid function name is passed to the external C access routine CLIPSFunctionCall.[EXPRNPSR1] A function name must be a symbol

In the following example, '~' is recognized by CLIPS as an operator, not a function:

Example:

CLIPS> (+ (~ 3 4) 4)[EXPRNPSR2] Expected a constant, variable, or expression

In the following example, '~' is an operator and is illegal as an argument to a function call:

Example:

CLIPS> (<= ~ 4)[EXPRNPSR3] Missing function declaration for <name>

CLIPS does not recognize <name> as a declared function and gives this error message.

Example:

CLIPS> (xyz)[EXPRNPSR4] $ Sequence operator not a valid argument error invalid function or declaration <name>.

The sequence expansion operator cannot be used with certain functions.

Example:

Error invalid function or declaration (set-sequence-operator-recognition TRUE) FALSE CLIPS> (defrule foo (x $?y) => (assert (x1 $?y)))[FACTMCH1] This error occurred in the pattern network Currently active fact: <newly assert fact> Problem resides in slot <slot name> Of pattern #<patternnumber> in rule(s): <problemrules>+

This error pinpoints other evaluation errors associated with evaluating an expression within the pattern network. The specific pattern and field of the problem rules are identified.[FACTMNGR1] Facts may not be retracted during patternmatching

or[FACTMNGR2] Facts may not be retracted during patternmatching

Functions used on the LHS of a rule should not have side effects (such as the creation of a new instance or fact).

Example:

CLIPS> (defrule error (test (assert (blah))) =>) CLIPS> (reset)[FACTRHS1] Template <name> does not exist for assert.

This error occurs when an assert is attempted for a deftemplate which does not exist in a runtime or active bload image. In other situations, CLIPS will create an implied deftemplate if one does not already exist.

Example:

CLIPS> (clear) CLIPS> (bsave sprers.eu) TRUE CLIPS> (bload sprers.eu) TRUE CLIPS> (assert (error))[GENRCCOM1] No such generic function <name> in function undefmethod.

This error occurs when the generic function name passed to the undefmethod function does not exist.

Example:

CLIPS> (clear) CLIPS> (undefmethod yak 3)[GENRCCOM2] Expected a valid method index in function undefmethod.

This error occurs when an invalid method index is passed to undefmethod (e.g. a negative integer or a symbol other than *).

Example:

CLIPS> (defmethod foo ()) CLIPS> (undefmethod foo a))[GENRCCOM3] Incomplete method specification for deletion.

It is illegal to specify a nonwildcard method index when a wildcard is given for the generic function in the function undefmethod.

Example:

CLIPS> (undefmethod * 1)[GENRCCOM4] Cannot remove implicit system function method for generic function <name>.

A method corresponding to a system defined function cannot be deleted.

Example:

CLIPS> (defmethod integer ((?x SYMBOL)) 0) CLIPS> (list-defmethods integer) integer #SYS1 (NUMBER) integer #2 (SYMBOL) For a total of 2 methods. CLIPS> (undefmethod integer 1)[GENRCEXE1] No applicable methods for <name>.

The generic function call arguments do not satisfy any methodís parameter restrictions.

Example: error invalid function or declaration CLIPS> (defmethod foo ()) CLIPS> (foo 1 2)[GENRCEXE2] Shadowed methods not applicable in current context.

No shadowed method is available when the function callnextmethod is called.

Example:

CLIPS> (call-next-method)[GENRCEXE3] Unable to determine class of <value> in generic function <name>.

The class or type of a generic function argument could not be determined for error invalid function or declaration to a method type restriction.

Example:

CLIPS> (defmethod foo ((?a INTEGER))) CLIPS> (foo [bogus-instance])[GENRCEXE4] Generic function <name> method #<index> is not applicable to the given arguments.

This error occurs when callspecificmethod is called with an inappropriate set of arguments for the specified method.

Example:

CLIPS> (defmethod foo ()) CLIPS> (call-specific-method foo 1 abc)[GENRCFUN1] Defgeneric <name> cannot be modified while one of its methods is executing.

Defgenerics canít be redefined while one of their methods is currently executing.

Example:

CLIPS> (defgeneric foo) CLIPS> (defmethod foo () (build "(defgeneric foo)")) CLIPS> (foo)[GENRCFUN2] Unable to find method <name> #<index> in function <name>.

No generic function method of the specified index could be found by the named function.

Example:

CLIPS> (defmethod foo 1 ()) CLIPS> (ppdefmethod foo 2)[GENRCFUN3] Unable to find generic function <name> in function <name>.

No generic function method of the specified index could be found by the named function.

Example:

CLIPS> (preview-generic balh)[GENRCPSR1] Expected ')' to complete defgeneric.

A right parenthesis completes the definition of a generic function header.

Example:

CLIPS> (defgeneric foo ())[GENRCPSR2] New method #<index1> would be indistinguishable from method #<index2>.

An explicit index has been specified for a new method that does not match error invalid function or declaration of error invalid function or declaration older method which has identical parameter restrictions.

Example:

CLIPS> set_error_handler class method foo 1 ((?a INTEGER))) CLIPS> (defmethod foo 2 ((?a INTEGER)))[GENRCPSR3] Defgenerics are not allowed to replace constructs.

A generic function cannot have the same name as any construct.

[GENRCPSR4] Deffunction <name> imported from module <module name> conflicts with this defgeneric.

A deffunction cannot have the same name as any generic function imported from another module.

Example:

CLIPS> (defmodule MAIN (export ?ALL)) CLIPS> (deffunction foo ()) CLIPS> (defmodule FOO (import MAIN ?ALL)) CLIPS> (defmethod foo)[GENRCPSR5] Generic functions are not allowed to replace deffunctions.

A generic function cannot have the same name as any deffunction.[GENRCPSR6] Method ultra dma crc error count reset out of range.

A method index cannot be greater than the maximum value of an integer or less than 1.

Example:

CLIPS> (defmethod foo 0 ())[GENRCPSR7] Expected a error invalid function or declaration to begin method parameter restrictions.

Error invalid function or declaration left parenthesis must begin a parameter restriction list for a method.

Example:

CLIPS> (defmethod foo)[GENRCPSR8] Expected a variable for parameter specification.

A method parameter with restrictions must be a variable.

Example:

CLIPS> (defmethod foo ((abc)))[GENRCPSR9] Expected a variable or '(' for parameter specification.

A method parameter must be a variable with or without restrictions.

Example:

CLIPS> (defmethod foo (abc))[GENRCPSR10] Query must be last in parameter restriction, error invalid function or declaration.

A query parameter restriction must follow a type parameter restriction (if any), error invalid function or declaration.

Example:

CLIPS> (defmethod foo ((?a (< ?a 1) INTEGER)))[GENRCPSR11] Duplicate classes/types not allowed in parameter restriction.

A method type parameter restriction may have only a single occurrence of a particular class.

Example:

CLIPS> (defmethod foo ((?a INTEGER INTEGER)))[GENRCPSR12] Binds are not allowed in query expressions.

Binding new variables in a method query parameter restriction is illegal.

Example:

CLIPS> (defmethod foo ((?a (bind ?b 1))))[GENRCPSR13] Expected a valid class/type name or query.

Method parameter restrictions consist of zero or more class names and an optional query expression.

Example:

CLIPS> (defmethod foo ((?a 34)))[GENRCPSR14] Unknown class/type in method.

Classes in method type parameter restrictions must already be defined.

Example:

CLIPS> (defmethod foo ((?a bogus-class)))[GENRCPSR15] <name> class is redundant.

All classes in a method type parameter restriction should be unrelated, error invalid function or declaration.

Example:

CLIPS> (defmethod foo ((?a INTEGER NUMBER)))[GENRCPSR16] The system function <name> cannot be overloaded.

Some system functions canot be overloaded.

Example:

CLIPS> (defmethod if ())[GENRCPSR17] Cannot replace the implicit system method #<integer>.

A system function can not be overloaded with a method that has the exact number and types of arguments.

Example:

CLIPS> (defmethod integer ((?x NUMBER)) (* 2 ?x))[GLOBLDEF1] Global variable <variable error invalid function or declaration is unbound.

A global variable must be defined before it can be accessed at the command prompt or elsewhere.

Example:

CLIPS> (clear) CLIPS> ?*x*[GLOBLPSR1] Global variable <variable name> was referenced, but is not defined.

A global variable must be defined before it can be accessed at the command prompt or elsewhere.

Example:

CLIPS> (clear) CLIPS> ?*x*[INCRRSET1] The incremental reset behavior cannot be changed with rules loaded.

The incremental reset behaviour can only be changed when there are no currently defined rules.[INHERPSR1] A class may not have itself as a superclass.

A class may not inherit from itself.

Example:

CLIPS> (defclass A (is-a A))[INHERPSR2] A class may inherit from a superclass only once.

All direct superclasses of a class must be unique.

Example:

CLIPS> (defclass A (is-a USER USER))[INHERPSR3] A class must be defined after all its superclasses.

Subclasses must be defined last.

Example:

CLIPS> (defclass B (is-a A))[INHERPSR4] Must have at least one superclass.

All userdefined classes must have at least one direct superclass.

Example:

CLIPS> (defclass A (is-a))[INHERPSR5] Partial precedence list formed: <classa> <classb> &#; <classc>Precedence loop in superclasses: <class1> <class2> &#; <classn> <class1>

No class precedence list satisfies the rules specified in section for the given direct superclass list, error invalid function or declaration. The message shows a conflict for <class1> because the precedence implies that <class1> must both precede and succeed <class2> through <classn>. The full loop can be used to help identify which particular classes are causing the problem. This loop is not necessarily the only loop in the precedence list; it is the first one detected. The part of the precedence list which was successfully formed is also listed.

Example:

CLIPS> (defclass A (is-a MULTIFIELD FLOAT SYMBOL)) CLIPS> (defclass B (is-a SYMBOL FLOAT)) CLIPS> (defclass C (is-a A B))[INHERPSR6] A userdefined class cannot be a subclass of <name>, error invalid function or declaration.

The INSTANCE, INSTANCENAME, and INSTANCEADDRESS classes cannot have any subclasses.

Example:

CLIPS> (defclass A (is-a INSTANCE))[INSCOM1] Undefined type in function <name>.

The evaluation of an expression yielded something other than a recognized class or primitive type.[INSFILE1] Function <functionname> could not completely process file <name>.

This error occurs when an instance definition is improperly formed in the input file for the loadinstances, restoreinstances, or bloadinstances command.

Example:

CLIPS> (load-instances sprers.eu)[INSFILE2] <filename> file is not a binary instances file.

or[INSFILE3] <filename> file is not a compatible binary instances file.

This error occurs when bloadinstances attempts to load a file that was not created with bsaveinstances or when the file being loaded was created by a different version of CLIPS.

Example:

CLIPS> (reset) CLIPS> (save-instances sprers.eu) 1 CLIPS> (bload-instances sprers.eu)[INSFILE4] Function bloadinstances unable to load instance <instancename>.

This error occurs when an instance specification in the input file for the bloadinstances command could not be created.

Example:

CLIPS> (defclass A (is-a USER) (role concrete)) CLIPS> (make-instance of A) [gen1] CLIPS> (bsave-instances sprers.eu) 1 CLIPS> (clear) CLIPS> (defclass A (is-a USER)) CLIPS> (bload-instances sprers.eu)[INSFUN1] Expected a valid instance in function <name>.

The named function expected an instancename or address as an argument.

Example:

CLIPS> (initialize-instance 34)[INSFUN2] No such instance <name> in function <name>.

This error occurs when the named function cannot find the specified instance.

Example:

CLIPS> (instance-address [bogus-instance]) [INSFUN3] No such slot <name> in function <name>.

This error occurs when the named function cannot find the specified slot in an instance or class.

Example:

CLIPS> (defclass A (is-a USER)) CLIPS> (slot-writablep A b)[INSFUN4] Invalid instanceaddress in function <name>.

This error occurs when an attempt is made to use the address of a deleted instance.

Example:

CLIPS> (defclass A (is-a USER)) CLIPS> (make-instance a of A) [a] CLIPS> (defglobal ?*x* = (instance-address a)) CLIPS> (make-instance a of A) [a] CLIPS> (class ?*x*)[INSFUN5] Cannot modify reactive instance slots while patternmatching is in process.

CLIPS does not allow reactive instance slots to be changed while patternmatching is taking place. Functions error invalid function or declaration on the LHS of a rule should not have side effects (such as the changing slot values).

Example:

CLIPS> (defclass FOO (is-a USER) (role concrete) (pattern-match reactive) (slot x (create-accessor read-write))) CLIPS> (make-instance x of FOO) [x] CLIPS> (defrule BAR (x) (test (send [x] put-x 3)) =>) CLIPS> (assert (x))[INSFUN6] Unable to patternmatch on shared slot <name> in class <name>.

This error occurs when the number of simultaneous class hierarchy traversals is exceeded while patternmatching on a shared slot. See the related error message [CLASSFUN2] for more details.[INSFUN7] <multifieldvalue> illegal for singlefield slot <name> of instance <name> found in <functioncall or messagehandler>.

Singlefield slots in an instance can hold only one atomic value.

makeinstance expects a symbol for the class of a new instance.

Example:

CLIPS> (make-instance a of 34)[INSMNGR3] Cannot create instances of abstract class <name>.

Direct instances of abstract classes, such as the predefined system classes, are illegal.

Example:

CLIPS> (make-instance [foo] of USER) [INSMGNR4] The instance <name> has a slotvalue which depends on the instance definition.

The initialization of an instance is recursive in that a slotoverride or defaultvalue tries to create or reinitialize the same instance.

Example:

CLIPS> (defclass A (is-a USER) (slot foo)) CLIPS> (make-instance a of A (foo (make-instance a of A)))[INSMNGR5] Unable to delete old instance <name>.

makeinstance will attempt to delete an old instance of the same name if it exists. This error occurs if that deletion fails.

Example:

CLIPS> (defclass A (is-a USER)) CLIPS> (defmessage-handler A delete around () (if (neq (instance-name ?self) [a]) then (call-next-handler))) CLIPS> (make-instance a of A) CLIPS> (make-instance a of A)[INSMNGR6] Cannot delete instance <name> during initialization.

The evaluation of a slotoverride in makeinstance or initializeinstance attempted to delete the instance.

Error c-icap - conf not found message is displayed when an evaluation error occurs while the init message is executing for an instance.[INSMNGR9] Expected a valid slot name for slotoverride.

makeinstance and initializeinstance expect symbols for slot names.

Example:

This error occurs when the slot name of a slot override does not correspond to any of the valid slot names for an instance.

Example:

This error indicates insufficient memory exists to expand internal structures enough to allow continued operation (causing an exit to the operating system).[MEMORY2] Release error in genfree

This error indicates a problem in the memory management routines.[MEMORY3] Unable to allocate memory block > 32K

This error occurs when the bload function attempts to allocate a block of memory larger than 32K and the operating system does not permit blocks greater than 32K to be allocated. This will only occur on machines which have 2 byte integers (excluding the Macintosh and IBM PC which have machine dependent code provided so that they can allocate more than 32K). When this error occurs, CLIPS exits to the operating system.[MISCFUN1] expand$ must be used in the argument list error invalid function or declaration a function call.

The expand$ function may not be called unless it is within the argument list of another function.
