problem with incompatible data types

Hi experts,

I have a problem with this procedure:

procedure TForm1.Button1Click(Sender: TObject);
var
  listitembuffer,colourbuffer: string;
  sl: tstringlist;
begin
  listitembuffer:=sl.strings[i];
  colourbuffer:=colourbuffer+listitembuffer;
  colourbuffer:=TrimColour(colourbuffer);
  edit1.text:=colourbuffer;
end;

The prototype of TrimColour is declared as:

 procedure TrimColour(var master: string);

Unfortunately, in the line

colourbuffer:=TrimColour(colourbuffer);


Delphi says:

"incompatible types "string" and "procedure", untyped pointer or untyped parameter."


Can you please tell me, why this line is not correct?

What must I do in order to copy the result of TrimColour to colourbuffer ?

With kind regards

Mathes

hi mathes

your trimcolour is a procedure not a function
change the line
colourbuffer:=TrimColour(colourbuffer);

to
TrimColour(colourbuffer);

hi mathes,

some problems are really easy, but sometimes the simple solution is not seen.
