Good, that would probably be what I need. Thanks!

Oops... this was 1.1 only. For 1.0.x (and still supported by 1.1, but
deprecated) it is ENDIAN_LITTLE and ENDIAN_BIG

The word you are looking for is 'Big Endian'. Have a google on 'Big Endian'
and 'Little Endian' on google.
this is a delphi routine, it may not work in FPC, certainly I would try it
first in Delphi compatibility mode, and with Intel style assembler syntax:
function Swap32(value : dword) : dword

Hi,
I need to read 2, 4 or 8 bytes in a processor independent way. For example:
I have 4 bytes ($12 $34 $56 $78), starting with the most signifikant (like
the 68k processor). Reading a DWord under i386 swaps the bytes ($78563412).
Is there a fast way/procedure to read a word/dword/qword independen
