How is a set, record and symbol in Delphi located in memory?
Well, for example, an array and a string, as I understand it, are links to an area in memory. What about sets, records, and char-a? How are they placed in memory?

Answer 1

The set is 256 bits. 1 - the element belongs to the set, 0 - does not.
