That is what I meant by IA 32/64. I did not suppose it can create
Inatium code <span class="moz-smiley-s1"><span> :-) </span></span>.<br>

I suppose this is because the API calls generated are 64 bit. Correct ?

No.

So you would need to compile/deploy both versions if you want the
customer to optionally take advantage of 64 bit. No problem IMHO.<br>
<br>
I suppose the 64 Bit OS takes care that any 32 bit program can run,
anyway. Correct ? <br>
<blockquote cite="mid:Pine.LNX.4.61.0710020950080.29045@idefix.wisa.be"

No, because if the program can run on 32-bit, the only adavtage to go for
64-bit is speed. But, FPC generates currently slower 64-bit executables
than 32-bit executables.

Oops ?!?! I supposed that using the much greater count of registers in
64 bit mode could speed up any kind of software. I suppose that the
experts <u>are </u>working on that, though.<br>

Thanks for your answers !<br>
