Re: [fpc-pascal] "Unexpected end of file" when having an open comment after the final "end."
No, the original post has the correct program, dropping a ";" in that spot is incorrect syntax. The problem comes in because there is an open comment, but no close comment. If you add the closing } the compiler behaves properly. On the other hand, I do understand that once the "end." is encountered, further processing is unnecessary, and so the error shouldn't occur, because any text showing up after that should be ignored. Honestly, it's is a case of six of one, half dozen of the other. It's all in the design of the compiler. I personally wouldn't consider it a bug, but I can see why some folks would, so On 2/8/2024 7:01 PM, Martin Wynne via fpc-pascal wrote: Hi Thomas, The error is not the file content after "end.".

This is inconsistent, why didn't the 1440.1 version reduce to a single? Because 1440.1 cannot be represented exactly as a single precision floating point number. Nor as a double or extended precision floating point number for that matter, and in that case the compiler uses the maximum precision is supported by the target platform.

Hello Martin, I've been using Pascal for more than 30 years now, but I must admit I've never before seen the construct you posted. And it doesn't compile either: project1.lpr(4,4) Error: Syntax error, "." expected but ";" found Kind regards, Thomas - Original Message - From: Martin Wynne via fpc-pascal To: fpc-pascal@lists.freepascal.org Sent: Thursday, February 8, 2024, 20:01:17 Subject: [fpc-pascal] "Unexpected end of file" when having an open comment after the final "end."

[fpc-pascal] "Unexpected end of file" when having an open comment after the final "end."
Hello all,
I'm unsure about whether or not to report this as a bug. Imho, it is a bug, but
maybe there's a good reason to handle this.
Please take the following example:
---start---
program test;
begin
end.
{
---end---
Result:
Z:\>ppc386.exe testproj.pas
Free Pascal Compiler version 3.2.2 [2022/05/15] for i386
Copyright (c) 1993-2021 by Florian Klaempfl and others
Target OS: Win32 for i386
Compiling testproj.pas
testproj.pas(6,1) Fatal: Unexpected end of file
Fatal: Compilation aborted
I'd say the code should compile without any errors for the following reasons:
1. The "end." tells the compiler that the file is finished here. Whatever comes
after this should not be considered by the compiler.
2. The compiler doesn't consider any other statement after "end.". For example,
replacing the open comment with something like "vra" doesn't cause an error
either.
Kind regards,
Thomas
