If I try to evaluate "$script(0", creating an error, sendmessage returns 1 and not 33

Code:
LPCWSTR l = "mIRC";
HANDLE file = CreateFileMapping(INVALID_HANDLE_VALUE, NULL, PAGE_READWRITE, 0, 4096, l);
LPSTR str = (LPSTR)MapViewOfFile(file, FILE_MAP_ALL_ACCESS, 0, 0, 0);
strcpy(str, "$script(0");
int ss = SendMessage(hwnd, WM_MEVALUATE, 0, 0);
