Hi,
basic questions here.

Is there any way to decide the number of elements in a set? there any way to traverse the elements in a set?

Regards Mikael

You can transverse a set with
    for ... in

See "loop with elements" in
https://wiki.freepascal.org/For

You can transverse a set with for ... in

Interesting, I learned something new, I did now know I could do this with FreePascal. It says it works for Strings and Arrays as well, does it also work for StringLists?

An even better:

for e in TEnum do ; // traverse every possible enum
for e in aSet do ; // traverse only enums in aSet

Yes

Couldn't you use PopCnt for that?
You would need to know the SizeOf() the type of the set in question.
