No, the base type of a set must be an ordinal type. Enumeration type and
integers. And the base type can't have more 255 elements
right... so a set has 0-255 elements and a set of sets would have 0-255 elements containing one set of 0-255 elements... if all are used, that gives 0-65535 elements we can access... or should be able to access... if we can figure out how to create it :(

What do you mean with "access"?
You can't access the element of a set, you can say if the an element is
in a set or not.
exactly... that's accessing it if it exists in the set...
msgAreas:=[1..7];
if (2 in msAreas) then .......
yup...
if (this.messages.area.num in UsersMsgTaggedAreas) then
begin
ScanForNewMessages(this.messages.area.num);
ScanForUserMessages(this.messages.area.num,this.user.name,this.user.nick);
end
else
inc(this.messages.area);
;)
