Pascal Error Illegal Expression

The source code is as follows: program TrafficFine; {$mode objfpc}{$H+} uses {$IFDEF UNIX}{$IFDEF UseCThreads} cthreads, {$ENDIF}{$ENDIF} Classes,SysUtils; var userInput : Char; Fine : Integer; TotalFine : Integer; DaysPassed: Integer; FineType : The following is invalid:  Procedure MyProcedure (A,B : Integer = 0);    Instead, this should be declared as  Procedure MyProcedure (A : Integer = 0; B : Integer = 0);    Error: Default parameter required for "arg1" The specified parameter requires a default value. PORFAVOR :) VolverNuevo Tema<<>> Vista: arbolcronológicoAyuda! Error: Invalid index for exported function DLL function index must be in the range 1..$FFFF.

Error: Forward declaration of class "arg1" must be resolved here to use the class as ancestor To be able to use an object as an ancestor object, it must be defined Lined up circle, n points boost 100ns pulse from 5 v to 10 v How to serve your dragon? Join them; it only takes a minute: Sign up Illegal expression in a pascal program up vote 0 down vote favorite My code below throws an exception. El caso es que al compilar mi código, en Pascal, me dice que PROCEDURE es una expresion ilegal y no se por que...

Error: Getter for implements interface must use the target's default calling convention. Error: Only virtual methods can be abstract You are declaring a method as abstract, when it is not declared to be virtual. What "actually" happens at T-minus-0 Why are there separate seasons for Archery and Firearm hunting for deer? This may, or may not be, a potential source of errors.

Turbo Pascal does not support function overloading. See the switch -Ss (see page 115). Error: type identifier not allowed here You cannot use a type inside an expression. Keep working you'll get there.

Therefore the current class has to implement the interface directly. Error: Cannot initialize variables declared as threadvar Variables declared as threadvar cannot be initialized with a default value. In TP and Delphi mode this is allowed for compatibility reasons. In order to make this clear in the source code, the compiler always requires the override directive to be specified when implementing overriding Objective-C or Java methods in Pascal.

Please do my Martian homework Why does everyone assume that the Architect was telling the truth about there being previous "Ones"? In line 9 and 10 you declare the global var IDNUMARR PAYMENTARR but you declare it again as a local var in the procedure DeclareandInitialiseArrays Almost all if-statements are invalid if(payment[j]=1620 Error: Objective-C classes cannot have published sections. Normally such a class should be derived from TPersistent.

You're trying to force the compiler into doing something it cannot do yet. Error: Illegal parameter list You are calling a function with parameters that are of a different type than the declared parameters of the function. Error: FAIL can be used in constructors only You are using the fail keyword outside a constructor method. Error: Illegal expression after message directive Free Pascal supports only integer or string values as message constants.

In Object Pascal, "published" determines whether or not RTTI is generated. Error: Message name "arg1" in inherited class is different from message name "arg2" in current class.

Error: class identifier expected This happens when the compiler scans a procedure declaration that contains a dot, i.e., an object or class method, but the type in front of the dot

PORFAVOR :)Angel(22/12/2011 03:24:03)Ayuda! Can droids be shut down manually? This error occurs in the following situation (example for Objective-C, but the same goes for Java interfaces):   Type MyProtocol = objcprotoocl;         ChildClass = Class(NSObject,MyProtocol)           ...         end;    where MyProtocol is declared but not defined. Error: No default property available You are trying to access a default property of a class, but this class (or one of its ancestors) doesn't have a default property.

You can only have them in classes. Error: Calling convention doesn't match forward This error happens when you declare a function or procedure with e.g. Error: No function result type specified for function "arg1" The first time you declare a function you have to declare it completely, including all parameters and the result type.

Error: Class "arg1" does not implement interface "arg2" The delegated interface is not implemented by the class given in the implements clause.

Does this use of std::make_unique lead to non-unique pointers? Are there any ambiguities created by merging I and J into one letter?

Use -WN if you want to debug win32 executables. Error: Class methods must be static in records Class methods declarations are not allowed in records without static modifier. Error: No common type possible between "arg1" and "arg2" To perform an operation on integers, the compiler converts both operands to their common type, which appears to be an invalid type. Correct declarations are:  const     p : procedure;stdcall=nil;     p : procedure stdcall=nil;    Error: The value for a property index must be of an ordinal type The value you use to index a property must be of

If the implementation is external, this rule is relaxed because Objective-C and Java do not have any override-style keyword (since it's the default and only behaviour in these languages), which makes Pascal-4First program using Pascal0Pascal program extracting words1Hexadecimal to Decimal Pascal Error Illegal Expression using Dev-Pascal-2Illegal Expression's Pascal (New Errors)0Pascal program exercise Hot Network Questions Bank claims I'm personally liable for small Use the {$MODE OBJFPC} or {$mode delphi} directives which load the unit automatically. procedure/function arg1 When using the -vd switch, the compiler tells you when it starts processing a procedure or function implementation.

Error: Some fields coming before "arg1" were not initialized In all syntax modes but Delphi mode, you cannot leave some fields uninitialized in the middle of a typed constant record. Methods with the same name always map to the same virtual method entry. Throws the error: fatal: syntax error ";" expected but "identifier AMOUNT" found Where should the semi-colon go? A final (typed) constant is read-only.

the final "begin end." is missing where you execute all your program. Error: Expression must be constructor call When using the extended syntax of new, you must specify the constructor method of the object you are trying to create. Headings of matrix in color Does using documentation as a developer make me look unprofessional? For instance cdecl and pascal are mutually exclusive.

This functionality is only supported to provide a compatible interface to C functions like printf. Error: Illegal expression This can occur under many circumstances.

Error: Self can only be an explicit parameter in methods which are message handlers The Self parameter can only be passed explicitly to a method which is declared as message handler. Error: Final method cannot be overridden: "arg1" You are trying to override a virtual method of a parent class that does not exist.

Hint: Type "arg1" redefinition This is an indicator that a previously declared type is being redefined as something else.
