Good to know thanks.


Here’s an example of something I’ve seen for debugging. I think that was kind of cool you could print types like that and I’m not sure how that would work in Pascal if at all. Maybe some RTTI magic perhaps.

{$define typestr(t):='#t: '+IntToStr(sizeof(#t))}

program macro_test;
uses
	SysUtils;

type
	MyRecord = record
		x, y, z: single;
	end;

begin
	writeln(typestr(MyRecord)); // MyRecord: 12
end.
