Go Up to Error and Warning Messages (Delphi)

This error message appears for syntax errors. There is probably a typo in the source, or something was left out. When the error occurs at the beginning of a line, the actual error is often on the previous line.

program Produce;
var
  I: Integer
begin               (*<-- Error message here: ';' expected but 'BEGIN' found*)
end.

After the type Integer, the compiler expects to find a semicolon to terminate the variable declaration. It does not find the semicolon on the current line, so it reads on and finds the ‘begin’ keyword at the start of the next line. At this point it finally knows something is wrong…

program Solve;
var
  I: Integer;       (*Semicolon was missing*)
begin
end.

In this case, just the semicolon was missing — a frequent case in practice. In general, have a close look at the line where the error message appears, and the line above it to find out whether something is missing or misspelled.

I don’t see any syntax error, my code compiles clean without the finalization section. Here is the last few lines of the unit.

function boolAsTF(b:boolean): string; inline;
begin
  if b then result := 'T' else result := 'F';
end;

finalization
  SyncMgr.Free;
end.

Have you tried putting an empty Initialization section ahead of the finalization one?

Jan 11, 2018 at 15:44
This is a trivial error. The fake code in v1 made this a terrible question; even the current version falls short of an MCVE.

Jan 12, 2018 at 3:39
Yes, it is a trivial error, but if you made it, it was hard to find an answer — I never noticed that finalization required initialization when I started coding in Delphi years ago and found it difficult to figure out when I made the mistake. That is specifically the only reason I documented it here. Just so Google will find the answer when you hit the error condition.

Jan 12, 2018 at 14:47
@CraigYoung — Just thought to check, already Google shows me as this question as the first hit when seaching for «E2029 Declaration expected but ‘FINALIZATION’ found» — so it would be nice if this were not down-voted, etc. out of existence. See the prior comment too.

Jan 12, 2018 at 15:19
@Gary Yes the title obviously makes this searchable; the only reason I didn’t vote to close. As for «hard to find the answer»: I really don’t see how, but do acknowledge I approach problem solving differently to many people. 1) Msg clearly indicates ‘surprise’ finalization is wrong. 2) This ‘special pairing’ concept is not unique/obscure: interface->implementation even begin/end or () 3) Find existing examples in code/otherwise — all would have initialization. 4) RTFM — as above, it’s clearly stated. Nutshell: If mistake is made: there are many obvious, accessible clues to fix it.

If you use a finalization section, you must also use an initialization section.

I accidentally hit this again, and remember this being hard to figure out the first time. So I thought I would document it here to help the next guy.

Kudos to MartynA who answered in a comment about as fast I I did when I knew I was going to answer it immediately.

Я новичок. В моей программе возникли такие ошибки:

[dcc32 Error] Project2.dpr(36): E2029 ‘;’ expected but ‘.’ found

[dcc32 Error] Project2.dpr(38): E2029 Declaration expected but end of file found

Вот программа, которую я написал:

program masquerader; //program nameVar //Declaring variables
Salary:integer; //Declared Salary as integer
procedure Sleep(milliseconds: Cardinal); stdcall;//Added sleep as a procedure for delay
Begin //Begins the program



  


                       
  



Writeln('Enter Your Salary please user...'); //Outputs line Enter Your salary please user...
Readln(Salary); //Recieves the value and declares the integer value to salary
Writeln('Processing your input...'); //Outputs line to Let the user know its being processed
Sleep(4000); //4 second delay
Writeln('Done!');
If (Salary>=5000) AND (Salary<=8000) Then //Conditions are being test for the requirements for each section
Writeln('Thanks for your Input file should be ready in a second'); // Outputs this line to let the user know it is ready in a second
Writeln('Congratulations!,You are eligible to play in poison'); //Outputs the section that matches the user's salary(5000-8000)
If (Salary>=3000) AND (Salary<=5000) Then //Conditions are being test for the requirements for each section
Writeln('Thanks for your Input file should be ready in a second'); // Outputs this line to let the user know it is ready in a second
Writeln('Congratulations!,You are eligible to play in Blue devils');//Outputs the section that matches the user's salary(3000-5000)
If (Salary<3000) Then //Conditions are being test for the requirements for each section
Writeln('Thanks for your Input file should be ready in a second'); // Outputs this line to let the user know it is ready in a second
Writeln('Congratulations!,You are eligible to play in The poor man section');//Outputs the section that matches the user's salary(x<=3000)
Writeln('Written by Timothy Adams');
Writeln('Fatima College 4-1');
Readln; //Declares the end of the read line
End. //End of program

ОТВЕТ:

Есть ряд проблем с вашим кодом.

Вы объявляете новую функцию Sleep(), не сообщая компилятору, где находится ее реализация. Таким образом, компилятор думает весь ваш код между begin и end является реализацией. Вот почему вы получаете ошибки, потому что вы завершаете реализацию функции end. вместо end;

Кроме того, блоки кода Delphi не определяются отступом, как вы предполагаете. Вам нужно использовать явные begin/ end операторы для группировки операторов вместе.

Попробуйте этот код:

program masquerader; //program nameuses
Windows;
Var //Declaring variables
Salary:integer; //Declared Salary as integer
//procedure Sleep(milliseconds: Cardinal); stdcall; external 'kernel32.dll'; //Added sleep as a procedure for delay



  


                       
  



Begin //Begins the program
Writeln('Enter Your Salary please user...'); //Outputs line Enter Your salary please user...
Readln(Salary); //Recieves the value and declares the integer value to salary Writeln('Processing your input...'); //Outputs line to Let the user know its being processed
Sleep(4000); //4 second delay
Writeln('Done!');
If (Salary>=5000) AND (Salary<=8000) Then //Conditions are being test for the requirements for each section
Begin
Writeln('Thanks for your Input file should be ready in a second'); // Outputs this line to let the user know it is ready in a second
Writeln('Congratulations!,You are eligible to play in poison'); //Outputs the section that matches the user's salary(5000-8000)
End;
If (Salary>=3000) AND (Salary<=5000) Then //Conditions are being test for the requirements for each section
Begin
Writeln('Thanks for your Input file should be ready in a second'); // Outputs this line to let the user know it is ready in a second
Writeln('Congratulations!,You are eligible to play in Blue devils');//Outputs the section that matches the user's salary(3000-5000)
End;
If (Salary<3000) Then //Conditions are being test for the requirements for each section
Begin
Writeln('Thanks for your Input file should be ready in a second'); // Outputs this line to let the user know it is ready in a second
Writeln('Congratulations!,You are eligible to play in The poor man section');//Outputs the section that matches the user's salary(x<=3000)
End;
Writeln('Written by Timothy Adams');
Writeln('Fatima College 4-1');
Readln; //Declares the end of the read line
End. //End of program

Кстати, ваш код не обрабатывает Salary выше 8000.

Hello everyone, I am currently facing an error that has appeared and is persistent.

I supplemented my Delphi code with two personalized procedures and discovered that by pressing
\ \ \ \ \ crtl\+shift\+c\ \ \ \
, I could automatically generate the functions. I followed this process to achieve the desired outcome.

Presently, my predicament is that I eradicated the automatically generated material since it was unnecessary. Regrettably, my code is no longer functional due to an error that has been triggered.

The end of the file was found, but a declaration was expected (error code E2029).

The code was anticipated to initialize, but instead, at line 520 (520:1), it encountered the end of the file.

I am struggling with fixing my code. Simply adding or removing an ‘end’ at the end of the file is not resolving the issue. Is there a method to identify where the problem lies in my code? Although my Delphi code is 500 lines, sharing it might not be helpful in this situation.
