This simply means that the sies of pointer and dword (ptruint) might differ on some systems (notably 64bit ones). In other cases, it could also mean that one or both ofthe types might vary in size or range dependent on the system used, and that this might lead to a possible disparity between the sets of possible values, i.e. that there might be values one of the tpes can assume, that the other cannot. Trying to convert such values _SHOULD_ in any case lead to an error - if recognizable on compiling, a compiler error, if only recognizable at runtime, at least an exception (range check or so) and possibly a program abort (and an appropriate message). BTW, a resolution for the case mentioned above would be an appropriate definition of the "ptruint" type. This might be tricky if conditional compilation will not work, because the compiler doesn't take into account what condition is in effect when it recognizes such a case. You might end up having to conditionalize any and all such cases individuall at the very place where they occur... -- (Weitergabe von Adressdaten, Telefonnummern u.ä. ohne Zustimmung nicht gestattet, ebenso Zusendung von Werbung oder ähnlichem) ----------------------------------------------------------- Mit freundlichen Grüßen, S.
