Delphi error meaning?

[D3adly]

on Delphi (version 10.4) I see these blue dots on the side of my code, but I have no idea what they mean and google confuses me even more
want to know if anyone here knows what it means

Looks like breakpoint toggles, i.e. if you click on them they probably turn another color and when running the program it would stop on any that isn't blue for debugging purposes.

I dont think they are breakpoint toggles, when you click on them they turn red, but that happens when you click every line of code, not just the ones that show blue

That's how breakpoint toggles typically behave. Try running your program in debug mode and check if it stops on the ones that are red. It'll probably not stop on lines that didn't have a blue toggle, even if the UI allows you to enable one there.

From an old Delphi forum post it seems they are indeed break points: http://www.delphigroups.info/2/11/102867.html

The blue dots is where you can put your breakpoints. They indicate "active
code" which is being executed. You may have some "dead code" which never is
executed, this code will not have blue dots, and you can't place a
breakpoint there. Try it out.
