Hi,
I need a new boolean type in my applications that support three
values. True, False and Null. Null value means undefined and has
various uses and gets handled differently to True or False. Is this
possible in Free Pascal?
Regards,
- Graeme -
type
TGraemeBoolean = (dbNil, dbFalse, dbTrue);

Dope! Now why didn't I think of that. :-)

Have a look at $packenum btw if you go that way.
what's the reason? i guess it's not to be used for streaming operation.
btw, is there $packsets? (for sets aligment?)
thanks,

Well, you never know. Shared memory is another possibility btw.

No, not
No, not that I know.
sets are always 32-bit size?

That documentation is not really complete. The supported settings are:
* FIXED, DEFAULT, NORMAL: the default
