Question

I’d like to know how I can delete numbers from a String. I try to use StringReplace and I don’t know how to tell the function that I want to replace numbers.

Here’s what I tried:

StringReplace(mString, [0..9], '', [rfReplaceAll, rfIgnoreCase]);

Simple but effective. Can be optimized, but should get you what you need as a start:

function RemoveNumbers(const aString: string): string;
var
  C: Char;
begin
  Result := '';
  for C in aString do begin
      if not CharInSet(C, ['0'..'9']) then
      begin
        Result := Result + C;
      end;
    end;
end;
