Ah, yes! The Hello World Machine.

That's still 27 bytes too much. Let's design a CPU that has "Hello World" as a 
one-byte 
instruction, implement that CPU in a Field-programmable gate array, write an OS 
for it and let it 
say hello. That's HelloWorld ad absurdum.

Re: [fpc-pascal] Procedures that work like WRITELN()

[DougC via fpc-pascal]

It would be very useful if WriteStr() was a function that returned the 
resulting string instead of returning it via an output parameter. Then you 
could just wrap the Writeln parameters in WriteStr() and pass it to the new 
logging procedure. Unfortunately, the ISO extension did not end up doing that!

Re: [fpc-pascal] Pause Key

[DougC via fpc-pascal]

I think any function where you provide the key code value and obtain the status 
of the key should work.



>From the Linux Documenation Project:

The two keys 
PrintScrn/SysRq and Pause/Break are special in that they have two 
keycodes: the former has keycode 84 when Alt is pressed simultaneously, 
and keycode 99 otherwise; the latter has keycode 101 when Ctrl is pressed 
simultaneously, and keycode 119 otherwise.___

Re: [fpc-pascal] Working on a new way to educate people about pascal

[DougC via fpc-pascal]

Well, this discussion has not gone well at all!



I suggest that everyone relax and discontinue pursuing it. 



The response has been made that the example code in the tutorial is more 
complicated than it should be. Digressions on SQL and databases are not 
relevant. Nor are comments on grammar. Let it be.

Re: [fpc-pascal] Program efficiency

[DougC via fpc-pascal]

Maintaining understandable and readable code is often more important that 
runtime efficiency. Like others have said, there are likely many additional 
places you can address overall efficiency before dealing with these 
calculations.

Sounds to me that if the compiler will probably insert temp variables anyway, 
then I might as well make my own and make it easier to understand later.

Re: [fpc-pascal] StrToInt is using ShortString buffer?

[DougC via fpc-pascal]

So, are you saying the one cannot declare an IntToStr function with the string 
represented by a PChar argument? Seems pretty straightforward to me.



Isn't that what is being requested?

Alexey-



You can always create such a function yourself,  gain experience using it, and 
share the source with us. That way others can gain experience with it and maybe 
someday also ask for it to be added to the standard library.








While that is in general the case, here this is not that easy, cause as Michael 
wrote, Val is an intrinsic which is fact backed by multiple function and the 
compiler itself needs to call them correctly. So in this case to play around 
with it means adjusting *both* the RTL and the compiler.

Hello. As I see in the commit 
https://gitlab.com/freepascal.org/fpc/source/-/commit/beecbf1581a986f544fde77aa428e05c21a35f6f

StrToInt always uses ShortString buffer:

Function fpc_Val_SInt_ShortStr(DestSize: SizeInt; Const S:
ShortString; out Code: ValSInt): ValSInt;

If it is correct: Can we skip using ShortString buffer and have e.g.
'common' PChar base function for AnsiString/ShortString?--

Re: [fpc-pascal] freepascal.org SSL_ERROR_BAD_CERT_DOMAIN

[DougC via fpc-pascal]

You can add Firefox on Windows 10 which also sees this error. 



Seems not to be a browser issue. If the user requests an https: connection, the 
website should NOT revert to a http: connection. Instead it should return an 
error if the https: connection cannot be made.

You can add the SeaMonkey web browser on FreeBSD to the list.

Re: [fpc-pascal] Writing Pascal Physics and Vectors

[DougC via fpc-pascal]

I would be helpful if you could meld this work into other Pascal-based efforts, 
such as the Castle Game Engine. I don't know the details of CGE but if it could 
use more of this type of functionality, why not make your work even more useful 
by connecting up with CGE?

Seems to be GMane...
I repeated the posting via email instead and this appears in the GMane listing.
So their posting function seems to have broken for the lazarus list. :(
