I would like the TMemo object to have a 250 line scroll buffer. In other words, 
when the 251 line is added, the first line is removed from the TMemo object. Is 
there a way to accomplish this without having to copy each string from index n to 
index n - 1 each time the 250th line is added?

Answer:

You can use TStrings' Delete method and pass the index to it.

1   if memo1.Lines.Count = 251 then
2     Memo1.lines.Delete(0);
