That would be great.

It is not that difficult.

{ = begin
} = end

and the other stuff is quite similar.

Pascal and C are close related.

It could be made with a compiler switch to determine if the compiler is in the Pascal or in the C compiling mode.

No more need to translate (huge amount of) C code. :-)

That would be great.

Nope

Syntax is easy, well once you have fully working preprocessor too, but how about libraries? How will you convert scanf/printf/puts/etc? What if it uses 3rd party libraries?

Pascal and C are close related.

Only at the surface. There are many semantics differences that's not .: ALL C expressions are potentially a boolean
expression which in turn has boolean value, while in Pascal, only boolean expression has boolean value. At syntax level, there's no Pascal equivalent of C's comma (sequence) operator. Argument evaluation in C is strictly right to left, in Pascal it's up to the compiler. A silly but valid C statement:

printf("%d%d%d\n",i++,++i,++i,i++);

would be hard to convert to Pascal automatically without blowing out the compiler.

No. Pascal and ALGOL are closely related, C and ALGOL are closely related. Pascal and C are not so closely related.

If you're looking for commonality go and use ALGOL, rather than making suggestions that are bound to result in a lot of sound and fury :-(

C's comma (sequence) operator is possible to use in Pascal:

function printf(fmt: PAnsiChar): Integer; cdecl; varargs; external
'msvcrt.dll' name 'printf';
begin
  printf('%d%d%d'#10,1,2,3,4);
end.

C's comma (sequence) operator is possible to use in Pascal

But your example doesn't show its use, probabyl you don't understand which comma operator I mean. Comma is used both as operator and argument/parameter separator in C, what I mean is the former, what you show is the latter. Here's the wikipedia article to make you understand: https://en.wikipedia.org/wiki/Comma_operator

In that case you are right.

In our previous episode, Mark Morgan Lloyd said:

Did ALGOL standarize the preprocessor? The high reliance on preprocessor is often a hinderance in automated C conversion.

As you can see here Pascal, C, and Basic are very close related.

By that logic C#, C++, VB.net and F# must be closely related as well, because Microsoft is providing compilers for all four...

No, C and Pascal are *not* closely related. And it surely isn't done with replacing begin and end with curly brackets!

If you want to believe that BASIC- as originally implemented- and ALGOL are related then go ahead and do so. But the politest thing I can say is that it doesn't make you look particularly well-informed.

Burroughs ALGOL (-60 implied) had include and define as part of the language. I think they were later moved into a preprocessor to make it possible to implement them on smaller computers.

Sorry, having a bad day so rushed.

You can go to the company and say poliltely to them that they are not well informed. I don't know if they take you serious.

Hi.

Please continue this thread to the fpc-other list.

I think you are jumping to conclusion here.
It is more likely that they spend the time in the past (they are around for quite a while) to build their specific Basic, Pascal and C compiler front end and just have to replace the actual code generator for each architecture they support.
Just because a company offers compilers for various languages, with a common IDE, doesn't mean that those compilers are "closely related". Just take Borland of old, Turbo Pascal, Turbo C, Turbo Basic, Turbo Prolog, they all used a very similar IDE but the actual compiler had all completely different origins...
