type
  TCharSet = set of Char;   



function StripNonConforming(const S: string;
  const ValidChars: TCharSet): string;//Removes characters you tell it to.
var
  DestI: Integer;
  SourceI: Integer;
begin
  SetLength(Result, Length(S));
  DestI := 0;
  for SourceI := 1 to Length(S) do
    if S[SourceI] in ValidChars then
    begin
      Inc(DestI);
      Result[DestI] := S[SourceI]
    end;
  SetLength(Result, DestI)
end;
function StripNonNumeric(const S: string): string;//Removes numbers
begin
  Result := StripNonConforming(S, ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9'])
end;
