You can use Copy() to get left, right and mid characters and StringReplace() to replace and Delete() to remove.

Hi Ziolko,

Thanks for your answer

Would you use the pos function with the copy()? Do you have any example of this?

With string replace I have tried:

StringReplace(aString, ' ' ', ' ', [rfReplaceAll, rfIgnoreCase]); and get an error message, how can I get rid of ' (apostrophe).

Is there a split function or a way to get round this?

1. use: StringReplace(aString, '''', '', [rfReplaceAll, rfIgnoreCase]);
(You have to double each: >>'<< within string)

2. yup You can use Pos() with Copy()
var s: string;
     hello, world: string;
     delim: Integer;

s := 'Helo Wrold';
delim := Pos(' ', s);
hello := Copy(s, 1, delim - 1);
world := Copy(s, delim + 1, MaxInt);

probably need to double up the '

StringReplace(aString, ' '' ', ' ', [rfReplaceAll, rfIgnoreCase]);

Here is another split string function I have been using.
Passes back the first string up to the delimiter while also trimming the original string.

function SplitStr(Var AString : String; ADelim : String) : String;
var APos : Integer;
begin
  Result := '';
  APos := Pos(ADelim,AString);
  if APos > 0 then
  begin
    Result := Copy(AString,1,APos-1);
    AString := copy(Astring,APos+length(Adelim),MaxLongInt);
  end
  else
  begin
    Result := AString;
    AString := '';
  end;
end;
