OK. I cannot help with BCB and i only have delphi5 pro and delphi6
personal edition for testing, investigating and experimenting. I was
thinking
more of a delphi6 feature something like ifdef delphi6 then define enh_int64
but i didn't know of a propper way to do it (and i forgot to write what i
wanted)

This way it would work only for bitcheckbox only in delphi6 until there is
time
to investigate it deeper.
I don't expect delphi3 to handle int64 very good in the future since there
is no
work on updating it any more. And if i know correctly Variant does not
support
int64 until delphi6. So it is a "feature" for delphi6 only ... :(
(unfortunately)

Please correct me if you think it's not ok (about doing it only for delphi6
and maybe
the last BCB)
