[fpc-pascal] Question about Deleting elements in Dynamic Array

[Bihar Anwar]

Just say, I have a dynamic array with size=5, and I want to delete elements from the index 0 to 2. Is there a trick (the fastest way) to delete those elements (0 to 2) without moving activities?

I've tried to make the dynamic array just pointing to 3rd element and set a new length for it, but fpc generates an unhandled exception.

var
  a: array of string;

SetLength(a, 5);
a[0] := 'aa'; a[1] := 'bb'; a[2] := 'cc'; a[3] := 'dd'; a[4] := 'ee';

a := @sl[3];       // this is the trick, but it doesn't work.
SetLength(a, 2)


Thank's in advance.
