Summary	0035663: For a string that ends with the delimiter, split returns one string too little.
Description	In my opinion Split should return three strings for a string with two delimiters, even if the last one is an empty string.
Steps To Reproduce	The following example is a nice way to try it out. procedure TForm1.Button1Click(Sender: TObject); var Zeile: String; Spalte: TStringArray; begin //Zeile := 'F0;F1;F2'; // High(Spalte) = 2 = Ok //Zeile := ';F1;F2'; // High(Spalte) = 2 = Ok //Zeile := ';;F2'; // High(Spalte) = 2 = Ok //Zeile := 'F0;;F2'; // High(Spalte) = 2 = Ok //Zeile := ';;'; // High(Spalte) = 1 = Falsch //Zeile := 'F0;F1;'; // High(Spalte) = 1 = Falsch //Zeile := 'F0;;'; // High(Spalte) = 1 = Falsch Zeile := ';F1;'; // High(Spalte) = 1 = Falsch Spalte := Zeile.Split(';'); LabelSpaltenIndex.Caption := IntToStr(High(Spalte)); Label_Index_0.Caption := Spalte[0]; Label_Index_1.Caption := Spalte[1]; Label_Index_2.Caption := Spalte[2]; end;

Michael Van Canneyt 2019-06-02 11:39 administrator ~0116528	I re-checked, the current behaviour is Delphi compatible. But I agree it is not logical behaviour. I have added a line to the documentation to make this clear.

Michael Van Canneyt 2019-06-03 08:36 administrator ~0116545	Update: It seems the behaviour became more logical in Delphi Rio, so I adapted the implementation to match Delphi Rio. (see related bugreport) It should now behave as you (and I :) ) expect !
