If an object file loaded with a $L or $LINK directive is not in the correct format in your delphi program, this error occurs. There are a few requirements that must be met: Check the help file for naming restrictions on segment names. There should be no more than ten portions. There should be no more than 255 external symbols. In LNAMES data, there are…

When the compiler expects a type, but instead finds a symbol that is neither a constant (a constant might start a subrange type) nor a type identifier, this error message appears. ExceptionClass is a variable, not a type, in this case. Make certain that you specify a type. Perhaps the identifier is misspelt or obscured by another identifier, such as one from another unit.

When the delphi compiler encounters the beginning of a scale factor (an ‘E’ or ‘e’ character) in a number, but no digits follow it, this error notice appears. We placed a space after ‘3.0E’ in the example; the number now terminates here for the compiler, and it is incomplete. We could have just erased the blank, but we prefer the look of a ‘+’ symbol.

When you open a comment but don’t close it, you get this error in your delphi program. A comment that begins with ” must end with “, while a comment that begins with ‘(‘ must end with ‘)’. As a result, the example did not close the comment. This will fix the problem.

In your Delphi program, You’ve declared a procedure but haven’t specified a result type for it. Either you meant to declare a function or the result type should be removed. DotProduct was actually intended to be a function, but we used the wrong term. When declaring a function, be sure to specify a result type; when declaring a procedure, make sure to indicate no result…

You’re attempting to reuse the name of an identifier that has previously been declared in this scope. Because the program’s name and the variable’s name are the same, we must modify one of them to make the compiler happy.

The use of file types as function result types is not permitted in Delphi. A file cannot be returned from a function. The file can be ‘returned’ as a variable parameter. You can allocate a file dynamically and return a pointer to it as an alternative.

When the syntax ‘Typename.Methodname’ is used, but the typename does not belong to an object or class type, this error message is displayed. TInteger has a Create method that Type Integer does not. Make that the identification refers to an object or class type; it could be misspelt or obscured by another unit’s identity.

You were attempting to call a regular method by simply providing the class type, rather than an actual instance. Normal methods and destructors are not allowed, only class methods and constructors. The example attempts to destroy the type TMyClass, which is illogical and so unlawful. As you can see, we intended to destroy the type’s instance rather than the type itself.

When an expression is used as a condition, it must be of the Boolean type to produce this error message. This is true for the if, while, and repeat statements’ controlling expressions, as well as the expression that controls a conditional breakpoint. A pointer variable was used as the condition of an if statement in this case by a C++ writer. In this scenario, you…

This error message is issued when an identifier given in the parameter list to New is not a constructor. By mistake, we called New with the destructor, not the constructor. Ensure that the New standard function has a constructor, otherwise it will not work.

At this point, the compiler demanded an ordinal type. The predefined types Integer, Char, WideChar, Boolean, and specified enumerated kinds are known as ordinal types. Ordinal types are needed in a variety of situations: An array’s index type must be ordinal. The low and high bounds of a subrange type must be ordinal type constant expressions. An ordinal type must be the element type of…

This error message appears in your delphi program when the declaration of a procedure, function, method, function Object() { [native code] }, or destructor differs from its previous (forward) declaration. This error message also appears when you attempt to override a virtual method, but the overriding method has a different parameter list, calling convention, and so on. As you can see, there are several possible…

This error occurs when you try to write a type that isn’t permitted in a Write or Writeln statement in your delphi program. It would have been easier to use a writeln statement to output Color, wouldn’t it? Unfortunately, that is not legal, and we have to do it with an auxiliary table.

The compiler was unable to locate the specified identifier; it was most likely misspelt at the time of declaration or use. It could be from a different unit that doesn’t have a uses clause. The variable was declared as “Counter” but was used as “Count” in the example. Either update the declaration or the places where the variable is utilised as a solution. We changed…

When you try to change a read-only object like a constant, a constant argument, the return value of a function, read-only properties, or fields of read-only properties in your delphi program, you’ll see this error message. You can tackle this problem in one of two ways: So that the assignment is legal, change the definition of whatever you’re assigning to.Remove the task entirely from the…

When there are many case labels in your delphi program with the same value in a case statement, this error notice appears. We didn’t pay attention here, and the case label 0 was specified twice. How to fix it? When you have symbolic constants and ranges of case labels, the problem may not be obvious; you may need to write down the true values of…

When a call to a procedure or function in your delphi program returns fewer parameters than those indicated in the procedure or function declaration, this error message appears. Calls to standard procedures or functions can also cause this. The procedure Val provides one more parameter in which to return an error code. That parameter was not included in the example. Typically, you will compare the…

The compiler discovered an illegal character in Delphi program. Errors with string constants or comments are the most common cause of this error message. In this case, a programmer reverted to C++ conventions and quoted a string with double quotes. The solution is to use single quotation marks. In general, you should remove the illegal character.

Only declarations, not statements, are allowed in the interface of a unit in your delphi program. Transfer the procedure bodies to the part where they will be implemented. In the interface portion, we went carried away and gave MyProc a body. The body must be moved to the implementation section, after which everything will be great.
