Re: [fpc-pascal] Pointer question

Playing around I had a more questions about pointer operations I've never used myself. 1) what does "i := x - x;" do and what is it's purpose and why doesn't "x + x" work the same? 2) I've used pointer equality of course but what does "x > p" do and what is its purpose? === var

[fpc-pascal] Printing unicode characters

ChatGPT is saying I can print unicode scalars like that but i don’t see it works and no compiler warnings even. Did it make this up or did I do something wrong? Writeln('Unicode scalar 1F496: ', #$1F496); // 💖 Writeln('Unicode scalar 1F496: ', WideChar($1F496)); // 💖 Regards, Ryan Josep

[fpc-pascal] Incremental compiling not working in new version

I just noticed I didn’t update my compiler since 2023/03/03 and finally did so today. After making some required changes I noticed the compile times went down from basically instant (after being fully built once) to taking 4+ seconds every build. Looking at the output it looks to me like it’s not
