From the reference guide, december 2008 version: "Dynamic arrays are reference counted: assignment of one dynamic array-type variable to another will let both variables point to the same array. Contrary to ansistrings, an assignment to an element of one array will be reflected in the other: there is no copy-on-write."
This is fine, but what is strange is that calling setlength DOES perform copy-on-write! var a, b : array of longint; begin setlength (a,2); b := a; setlength (a,5); writeln (length(b)); // I get 2, not 5 end. Why this inconsistency? Seems like the behaviors for assigning an element and for using setlength should be similar.
