Immutable = Pointer?

[noszone]

Hello,

I have a question. Is Immutable = Pointer? or Immutable = any variable in Pascal?

For instance:

Code: Pascal  [Select][+][-]

1. var a, b:integer;
2. begin
3. a:=2;
4. b:=a;  //Is b now pointed to a reference or | b now have it's own value copy?

Value copy, since a and b are not pointers.
