I have considered 64 bit integers but there are a number of issues...

I've recently discovered that BCB3 (and Delphi3?) does not support
overloaded pascal functions, so I am going to have to remove some of
the overloads I already have in Telesis_Utils.pas if I want to provide
support for these versions. Similarly there are problems with 64bit
integers in these versions.

I use search mode a lot. For the bitcheck controls (I use
BitCheckList more than BitCheckBox) I need server side support for bit
manipulations to support search mode. Last time I looked the standard
UDF lib bit functions were still integer based.

I do have my own UDF library - with my own imlementations of the bit
functions - that I guess I could update to provide 64bit variations.
I am not sure of the exact requirements for this at the moment. It
seems that IB/FB provide reasonably automatic casting of integer to
int64 and back again (at least for generator values), but I am not
sure if I like this or whether I would want separate implementations.


I got the code you sent through. Hopefully the above notes will
explain my reservations about using that code asis. This needs more
investigation and experiementation.
