DLL Problem bei IntToStr und Uppercase

[Jackie1983]

das ist jetzt meine ganze dll

Delphi-Quellcode:

library Script;

uses
  ShareMem ,SysUtils,
  Classes, JvInterpreter, Tools_Scripte;

Procedure ScriptData(st : TScriptThread; pIdentifier: PChar; var Value: Variant; Args: TJvInterpreterArgs; var Done: Boolean); stdcall;
var
  lCommands : TStringlist;
  Identifier : string;
begin
  Identifier := String(pIdentifier);
  //...
  Identifier := lowercase(Identifier);
  lCommands.Text := lowercase(lCommands.Text);
  done := not( lCommands.IndexOf(Identifier) = -1);

  if Identifier = 'sleep' then      sleep(Args.values[0]);
  if Identifier = 'strtoint' then   value := StrToInt(Args.values[0]);
  if Identifier = 'uppercase' then  Value := Uppercase(Args.Values[0]);
  if Identifier = 'konsole' then    st.OutKonsoleP(Args.Values[0]);
end;

exports
  ScriptData;

begin
end.
