Subject: Pascal to Ruby


Been working on my line editor.  Just have the insert left.  Anyway... is
there a way to do this with a string method in ruby that I missed, or do I
have to code it out the same way...

BEGIN
  MaxLinesEntered := Succ (MaxLinesEntered);
  IF MaxLinesEntered > current_linenum THEN
    FOR i := MaxLinesEntered DOWNTO current_linenum DO MessBuff [i + 1] :=
MessBuff [i];
      MessBuff [current_linenum] := working_line;
      current_linenum := Succ (current_linenum);
     END;


Basically, I have an array of text in a buffer, and I need to be able to
insert at whatever point and move everyting UP .... with all the other cool
string stuff in ruby, I can't believe I will have to write that out.  Ideas?

Thanks for answering another dim question.
